And a magnetic field unit 1 including a magnetic circuit unit 5 that forms a magnetically closed magnetic path together with this, and an armature unit 2 including an electric circuit unit 6, and a field armature current collecting assembly 10 is provided.

The present invention relates to a generator motor such as a DC generator, a DC motor, and a generator / motor storage device.
Some DC machines have an alternating magnetic field and a DC magnetic field on the field side, and the multi-pole alternating magnetic field type has been widely used together with an AC machine as a DC machine with a commutator. On the other hand, the unipolar non-alternating magnetic field type is the first unipolar generator based on unipolar electromagnetic induction discovered by Michael Faraday in 1821. After that, Nikola Tesla and others tried to improve the monopolar machine, but the applications of low voltage and large current did not spread, and the DC power transmission and DC equipment did not become widespread, and AC power transmission and AC equipment became the mainstream and reached the present. .
However, since a DC power supply is required at the stage of actual use as a power supply, the technology of inverters and converters has produced a great technological innovation in power conversion today.
In recent years, as the problem of environmental energy has grown, the spread of distributed power sources has been desired. For example, an uninterruptible power supply UPS (Interruptable Power Supply) includes an AC output and a DC output. However, since the DC output is smaller than the AC output, the range of use has been limited. However, research and development of direct current power supply and direct current power transmission has progressed as power sources have been decentralized.
Furthermore, as a measure against renewable energy for environmental problems, the energy conversion of solar heat, solar light, hydropower, wind power, ocean (wave / ocean current / temperature difference / tide) geothermal, biomass, etc. is electricity. Recently, research and development of secondary batteries other than generators, fuel cells, capacitors, etc., especially as elemental technologies for decentralized energy, has progressed in the technology for conversion to electric power. We are accelerating technology for integrating functions.
US Pat. No. 523998 (FIGS. 1 and 2) JP-A-55-155571 (1 page, FIG. 1, FIG. 2, FIG. 3) Japanese Patent Laid-Open No. 9-238458 (page 4, FIG. 1, FIG. 2, FIG. 3) Japanese Patent No. 3127684 (page 1, page 4, FIG. 1, FIG. 2) US Pat.

A generator motor according to an embodiment of the present invention will be described below with reference to the drawings.
A first embodiment of the present invention is shown in FIGS.
FIG. 1 is a perspective view of a generator motor 20 in a power generation state. A field armature assembly 3 is configured by integrating a rectangular electric circuit portion 6 of an armature body 2 with a field body 1 from both sides. ing. The magnetic field generators 4a and 4b of the field armature assembly 3 are separated on both surfaces of the electric circuit unit 6, and one of the magnetic field generators 4a and the electric circuit unit 6 is insulated by an electric insulating unit 13a. A magnetic flux concentrating portion 14a is provided on the opposite surface of the magnetic field generating portion 4a, and a magnetic flux passage portion 15 is connected to the opposite surface of the magnetic flux converging portion 14a.
The magnetic flux passage portion 15 is connected to the magnetic flux converging portion 14 b by magnetically protecting the communication hole 16 of the electric circuit portion 6 with the magnetic shielding portion 17 and communicating with the opposite surface of the electric circuit portion 6. Another magnetic field generating part 4b is provided on the opposite surface of the magnetic flux converging part 14b, the opposite surface of the magnetic field generating part 4b is insulated by the electric insulating part 13b, and the opposite surface of the electric circuit part 6 is provided. Again, the field armature assembly 3 is integrally opposed with the electric circuit portion 6 interposed therebetween. The magnetic field generators 4a and 4b on both side surfaces are arranged in series in the order of the S-N-S-N magnetic poles as shown so that the magnetic circuit unit 5 is magnetically connected in series.
In the case of FIG. 1, the magnetic field generators 4a and 4b are on both sides of the electric circuit unit 6, but the magnetic flux generators 14a and 14b are electrically insulated even if only one of the magnetic field generators 4a and 4b is provided. Even if it directly opposes the electric circuit part 6 through the parts 13a and 13b, it functions sufficiently as the magnetic circuit part 5.
As the electric circuit portion 6 of FIG. 1, copper or copper alloy, aluminum or aluminum alloy which is a nonmagnetic metal is excellent in workability. The magnetic field generators 4a and 4b are permanent magnets, and are ferrite-based, alnico-based, particularly recently rare earth magnets with high energy products, specifically neodymium-iron-boron, samarium-cobalt, samarium-iron-nitrogen, praseodymium, Anisotropic magnets containing dysprosium are excellent.
Since the material of the magnetic flux concentrating portions 14a and 14b does not require an alternating current characteristic, a martensitic stainless steel material which is a material having a higher magnetic flux density saturation point and also serves as rust prevention is excellent. The electrical insulation parts 13a and 13b are particularly preferably resin-based industrial materials having excellent heat resistance and low temperature resistance.
Further, the electric sliding portion 7 on the inner peripheral surface of the sliding hole 18 at the two ends of the armature body 2 in FIG. 1 and the current collecting sliding portion 9 of the two current collectors 8 can move smoothly in a linear direction. ing. The electric sliding portion 7 and the current collecting sliding portion 9 also have a function of transmitting electricity while sliding to constitute a field armature current collecting assembly 10. In other words, the field armature current collecting assembly 10 is configured which has free linear motion while electricity flows from one side of the current collector 8 to the other. The current collector 8 is preferably a non-magnetic metal material that is excellent in conductivity, excellent in surface hardening, and increases the hardness by quenching.
1 and 2, the direction of the magnetic field orientation φ and the electromotive force V in the power generation state will be described.
In the field armature assembly 3, when a force is applied in the direction of the arrow F shown in FIG. 1 and a magnetic flux φ flows in the direction shown in the figure in the magnetic flux path 15, the direction shown in FIG. An electromotive force V is generated. The cause of the generation of the electromotive force V is that electromagnetic conversion is performed in the electromagnetic induction crossover portion 11 as shown in FIG.
The situation when electromagnetic conversion is performed is shown in more detail in FIG. 2 is a cross-sectional view of FIG. 1 as viewed from the front toward the drawing. When the field armature assembly 3 moves from the front side of the drawing toward the back side of the drawing, the electromotive force V is changed from the right side of the drawing according to the Fleming's right rule. Occurs toward the left.
Further, in the electromagnetic non-inductive crossing portion 12 of FIG. 2, the magnetic field orientation φ is opposite to that of the electromagnetic induction cross-over portion 11, so that electromagnetic conversion does not occur in the electromagnetic non-inductive crossing portion 12, that is, generation occurs. The electromotive force V and the magnetic field orientation magnetic flux φ are separated electromagnetically so as not to cross each other.
Specifically, as shown in FIGS. 1 and 2, the electromagnetic non-inductive crossing portion 12 is magnetically shielded by the magnetic shielding portion 17 at the gap where the communication hole 16 of the electric circuit portion 6 and the magnetic flux passage portion 15 communicate with each other. ing. Since the magnetic shielding portion 17 is intended for magnetic shielding, the surface of a silicon steel plate, particularly a directional silicon steel plate or permalloy (nickel alloy) is used after being electrically insulated, so that the magnetic flux passage portion 15 of the electromagnetic non-inductive crossing portion 12 can be used. The leakage magnetic flux in the cross-communication portion can be further reduced.
Alternatively, a material having a high saturation magnetic flux density that does not cause magnetic saturation between the communication hole 16 and the magnetic flux passage portion 15, for example, a pure iron material having a low carbon content, or a martensitic stainless steel material that is more resistant to rusting is used. By doing so, it becomes possible to further separate the magnetism from the electricity. Since it is a direct current electromagnetic conversion, it is not necessary to use a material with particularly good alternating current characteristics. Alternatively, the magnetic shielding portion 17 may be omitted if the magnetic flux passage portion 15 has a sufficient cross-sectional area so as not to be magnetically saturated and a sufficient gap is secured in the cross-communication portion of the magnetic flux passage portion 15.
Further, as shown in FIGS. 1 and 2, the electromagnetic induction crossover portion 11 and the electromagnetic non-induction crossover portion 12 are arranged on a substantially straight line along the direction of electromotive force during power generation or the direction of current flowing during power generation. . This is important, because the magnetic field generated according to the right-handed screw law in the direction of electromotive force generated during power generation in the electric circuit unit 6 and the direction of current flowing during motor driving is the electromotive force circuit that generates power in the electric circuit unit 6 and the current flowing during energization. When crossing at a right angle to the circuit, the magnetic field orientation φ at the electromagnetic induction crossover portion 11 is magnetically distorted due to the mutual induction action of the magnetic field of the field body 1 and the induction magnetic field generated in the electric circuit portion 6. The electromagnetic conversion is also distorted and becomes a direct current including noise, and the electromagnetic conversion efficiency is also lowered. Therefore, as described above, the arrangement where the electromagnetic induction crossover portion 11 and the electromagnetic non-induction crossover portion 12 are in the same row as the electromotive force direction or the current direction is extremely effective for improving the efficiency of DC electromagnetic conversion for a single pole machine. It becomes a structure.
Next, FIG. 3 is a sectional view in which two field armature assemblies 3 of the first embodiment of FIGS. 1 and 2 are magnetically arranged in parallel and linearly arranged. By arranging in this way, the electric circuit section 6 of the plurality of field armature assemblies 3 becomes a series connection to which the generated induced voltage is added, and by repeatedly laminating this, high efficiency with less magnetostriction is obtained. An electromotive force can be obtained.
Next, the generator motor 30 in the power generation state of the second embodiment of the present invention is shown in FIGS. The armature body 32 shown in FIGS. 4 and 5 has electrical circuit portions 36 connected at right angles to both sides of an electrical connection portion 49, and electric sliding portions 37 connected to both sides thereof, and collects current in the same manner as in FIG. It freely slides in contact with the current collector sliding part 39 of the body 38.
The electric circuit portions 36 face each other in parallel, the magnetic field generating portions 34a and 34b are insulated between the electric circuit portions 36 in parallel by the electric insulating portion 43, and the inner sides of the respective magnetic field generating portions 34a and 34b. Further, both surfaces of the magnetic flux converging unit 44 are in contact with the same magnetic poles of the magnetic field generating units 34a and 34b. By selecting the magnetic material of the magnetic flux converging part 44 interposed between the same magnetic poles and matching the thickness between the magnetic poles of the magnetic flux converging part 44 with the saturation magnetic flux density, the electromagnetic induction crossing part shown in FIG. It is a feature of the present invention that the magnetic flux density of 41 is effectively increased.
As shown in FIGS. 4 and 5, the magnetic flux passage portion 45 is connected to the magnetic flux concentrating portion 44. The magnetic flux passage portion 45 passes through the communication hole 46 magnetically shielded by the magnetic shield portion 47 of the electrical connection portion 49 and is connected to the magnetic flux concentrating portions 44 on both side surfaces of each of the electric circuit portions 36. In addition, the electric connecting portion 49 and the magnetic flux passage portion 45 are crossed by the electromagnetic non-inductive crossing portion 42, and the magnetic flux concentrating portion 44 is integrally provided on the opposite surface of the electric circuit portion 6 through the electric insulating portion 43. ing.
The relationship between the magnetic field orientation φ of the magnetic field generators 34a and 34b during power generation shown in FIG. 4 and the direction of generation of the electromotive force V due to the direction of motion F of the field armature assembly 33 is shown in FIG. An electromotive force V is generated in the direction of the arrow in the drawing according to the Fleming's right-hand rule with respect to the direction of motion F (FIG. 4) from the front side of the drawing to the direction of the magnetic flux φ 41 and the magnetic flux φ of the magnetic field orientation.
In accordance with the magnetic field orientation φ of the magnets of the magnetic field generators 34a and 34b in FIG. 5, the magnetic field generator is unified into one by using the polar anisotropic magnet 50 shown in FIG. Since the magnetic flux converging unit 44 between the magnetic field generating units 34a and 34b is not necessary, the thickness can be further reduced. Further, by using the polar anisotropic magnet 50 as shown in FIG. 6, the electromagnetic non-inductive crossing portion 42 where the electrical connection portion 49 and the magnetic flux passage portion 45 intersect, and both side surfaces of the polar anisotropic magnet 50 are used. The magnetic circuit length of the entire magnetic circuit can be shortened by providing the electromagnetic non-inductive crossing portion 42 also in the electric circuit portion 36 of the magnetic circuit portion 36. The field body 31 including the magnetic field generating portions 34a and 34b of FIGS. Leakage magnetic flux of the magnetic circuit can be reduced. As a result, a high magnetic flux density required for electromagnetic conversion at the electromagnetic induction crossover portion 41 can be obtained, and higher efficiency can be realized.
The polar anisotropic magnet can be easily manufactured by applying an orientation magnetic field to the raw material in the manufacturing process as shown in FIG. The magnet material is preferably a rare earth magnet of neodymium / iron / boron (Nd—Fe—B), samarium / cobalt (Sm—Co), or samarium / iron / nitrogen (Sm—Fe—N). Other magnets include rare earth elements such as praseodymium (Pd) and dysprosium (Dy).
FIG. 7 shows that the magnetic circuit is symmetrical about the polar anisotropic magnet 50 by providing the electric non-inductive crossing portion 42 from the electric connecting portion 49 connecting the two electric circuit portions 36 of FIG. With this structure, the magnetic resistance of the magnetic circuit is further balanced, and a direct current with less noise can be obtained.
FIG. 8 shows a field armature assembly 33 in which a plurality of field bodies 31 of FIG. 5 are magnetically connected in parallel and a plurality of armature bodies 32 are connected in series. By doing so, a stacked type can be realized, whereby a high induced voltage can be obtained.
FIG. 9 is a diagram in which the electric circuit section 36 of the armature body 32 in the power generation state in FIGS. 4 and 5 is a parallel circuit. 4 and 5 has only one magnetic flux passage portion 45, the magnetic flux φ is likely to leak. Therefore, in FIG. 9, the magnetic flux density of the electromagnetic induction crossover portion 41 is further increased by providing another magnetic flux passage portion 45 on the opposite side of the magnetic flux passage portion 45 by making the axis connecting the pair of current collectors 38 symmetrical. It can be improved.
That is, as shown in FIG. 9, two current collectors 38 are shared, and two electric circuit portions 36 arranged on both sides of the axis between the pair of current collectors 38 are connected in parallel, and the inner side The magnetic flux concentrating portions 44 of the two electric circuit portions 36 are closed as a common magnetic flux converging portion 44, and the electromagnetic non-inductive crossing portion 42 separates electricity and magnetism. The magnetic flux density of the induction crossover part 41 can be kept high.
In FIG. 9, each of the two electric circuit portions 36 arranged on both sides of the axis line between the pair of current collectors 38 further includes a magnetic field generating portion 34 a that constitutes a field of one of the two electric circuit portions 36. If the magnetic field orientation φ of each of the magnetic field generators 34a and 34b constituting the magnetic field of 34b and the other two electric circuit units 36 is opposite to each other as shown in FIG. It becomes possible to operate as a common closed magnetic circuit.
Next, a generator motor 60 in a power generation state according to a third embodiment of the present invention is shown in FIGS. FIG. 10 and FIG. 11 show the rotational movement from the linear movement of FIG. The field armature assembly 63 is fixed integrally with the rotary shaft 80 and is rotatably supported by a bearing 81. Further, the fixed current collector 68 is in sliding contact as a positive electrode and a negative electrode at the cylindrical electric circuit end portions 82 on both sides of the electric circuit portion 66, respectively.
Further, as can be seen by comparing FIG. 10 and FIG. 11, in the case of FIG. 9, the relationship between the magnetic field orientation of the magnetic field generator 34a and the magnetic field orientation φ of 34b is opposite to each other across the magnetic flux converging unit 44. However, in the case of FIG. 10, the relationship between the magnetic field orientation φ of the magnetic field generator 64a and the magnetic field orientation φ of 64b is the same. This is because the magnetic field orientation φ of the magnetic circuit portion 65 differs depending on the difference between the linear motion and the rotational motion. Further, the rotating shaft 80 constitutes a magnetic circuit together with the magnetic flux converging portion 74 as a common magnetic circuit portion 65 of the magnetic flux passage portion 75 of the field body 61. Since the material of the rotary shaft 80 is preferably a magnetic material that can resist rust and corrosion, martensitic and ferritic stainless steel materials are excellent. The magnetic field generators 64a and 64b are permanent magnets, and are preferably made of the same magnet material as that of the first embodiment shown in FIGS.
11 is a cross-sectional view taken along the line AA in FIG. In this figure, four of the field armature assemblies 63 are equally arranged in the circumferential radial direction. However, at least one field armature assembly 63 can operate. Therefore, a plurality of field armature assemblies 63 can be arranged as necessary.
Further, since the plurality of field armature assemblies 63 rotate around the rotation shaft 80, the strength is reinforced by the rotating body 83 in order to balance the rotation strength and rotation between the field armature assemblies 63. . The material of the rotating body 83 may be any material that is excellent in electrical insulation and non-magnetism.
For example, if a vacuum-impregnated resin mold is used, the rotation balance is achieved and a compact rotating body is obtained. If heat resistance is taken into consideration, composite materials including ceramics and brittleness can be considered. In consideration of cost, in the case of a metal nonmagnetic aluminum alloy or austenitic stainless steel material, the surface is used after being electrically insulated. However, care should be taken because austenitic stainless steel becomes magnetic when subjected to strong cold working. Titanium alloy is good for light weight and high strength.
Next, a generator motor 90 in a power generation state according to a fourth embodiment of the present invention is shown in FIGS. FIG. 12 is a cross-sectional view of the electromagnetic equivalent circuit of the generator motor 90. FIG. 13 is a cross-sectional view of the arrow BB in FIG. 12 as viewed from the axial direction. 10 and FIG. 11 constitutes a parallel circuit, the purpose of this embodiment is to provide the electric circuit portions 96a, 96c, 96e, 96g, and 96i shown in FIG. 12 and FIG. , 96k and electric circuit portions 96b, 96d, 96f, 96h, 96j, 96l are alternately arranged equally in the circumferential direction of the rotating shaft 92, and the electric circuit portion 96a is connected to the electric circuit end portion 97a. The portion 96l is connected to the electric circuit end portion 97b, and the other electric circuit portions are connected in series by the electric circuit connecting portion 91, so that the number of the electric connecting portions 94 is kept to a minimum while the electric circuit portion 97l is connected. To achieve serialization.
The conventional monopolar machine has a problem that it is difficult to obtain a high induced voltage. If the number of electric circuits in series connection of armatures is increased in order to increase the induced voltage, the structure of the armature becomes complex, the effective magnetic flux that leaks increases, and the assembly of the armature becomes difficult. In general, there are two methods for series connection of armature electric circuits. One method is a series connection method in which electric circuits are reciprocated in a wavy manner between power supply terminals including a plurality of armatures connected in series. The other method is a method of connecting a plurality of armatures having an electric circuit that repeats overlapping one armature concentrically in series. However, whichever method is used, the forward and return paths of the armature electric circuit are mixed and crossed in the magnetic field, so that the effective magnetic flux that leaks increases and the structure becomes complicated.
The present embodiment solves the above problem by the following electric circuit route. When the rotational force F acts on the electric circuit unit 96a shown in FIG. 13 in the CW (clockwise) direction, the generated electromotive force V is collected from the positive electrode (+) of the current collector 98 shown in FIG. In the direction of the negative electrode (−) of the body 98, it passes through the electric circuit end portion 97a of FIG. 13, passes through the electric circuit portion 96a of FIG. 12, passes through the electric circuit connection portion 91, and passes through the electric circuit connecting portion 91. It passes through the electric circuit portion 96b that is divided and arranged in the circumferential direction.
What is important here is that the direction of the rotational force F and the direction of the electromotive force V are framing when the electromotive force V passing through the first electric circuit portion 96b enters from the field body 95b instead of from the field body 95a. This is consistent with the right hand rule. Further, the electromotive force V advances through the electric circuit portion 96b, and the last electric circuit portion 96b makes one reciprocation by exiting the field body 95d without passing through the field body 95e for the same reason as described above.
Similarly, in the forward path after the two round trips, the electromotive force V passes in the order of the electric circuit connecting portion 91, the electric circuit portion 96c, the electric circuit connecting portion 91, and the electric circuit portion 96d. The process is completed by passing through the connecting portion 91, the electric circuit portion 96k, the electric circuit connecting portion 91, the electric circuit portion 96l, the electric circuit end portion 97b, and the negative electrode (−) of the current collector 98.
By the above-described electric circuit path, each of the field bodies 95a to 95e achieves serialization of the electric circuit while maintaining one electric connection portion 94 at the upper or lower portion, and is balanced as a rotating body. The length of the magnetic path of the armature assembly 93 can be shortened, the effective magnetic flux to leak is small, the copper loss of the electric circuit is small, and a generator motor with high output density is realized.
In the fourth embodiment, the field armature assembly 93 includes five layers of field bodies 95a to 95e. However, by further increasing the number of stacked field bodies, the field bodies at both ends of the stack have electric circuit portions. The effect of electrical imbalance due to not passing is reduced.
The electric circuit connecting portion 91 and the electric circuit end portions 97 a and 97 b shown in FIG. 13 are electrically insulated from the rotating shaft 92 by the electric insulating portion 99. Further, the outer surface of the electric circuit portion 96a, the electric circuit connecting portion 91, and the electric circuit portion 96b is also electrically insulated and separated from each other.
Therefore, in the fourth embodiment of the present invention, the electric circuit form of the serial connection of the 12 rows arranged in a row in the circumferential direction of the rotating shaft 92 is shown, but the electric circuit form is not limited to this in each field body. It is possible to obtain a higher induced voltage by alternately connecting a plurality of electric circuit portions and a plurality of electric circuit connecting portions in series, and stacking them in a multilayer in the direction of the rotating shaft 92. Regardless of the multi-layered arrangement, the entire surface of the field body can be effectively used by freely dividing and arranging the electric circuit connection in the circumferential direction of the rotating shaft 92.
Further, the positional relationship between the positive electrode (+) of the current collector 98 and the negative electrode (−) of the current collector 98 equivalently sandwiching the electric circuit section is as follows. The rotational axis of the field armature assembly 93 is as shown in FIG. It may be located separately on both sides of the direction 92, or may be located together only on one side. The structure in which the positive electrode and the negative electrode of the current collector 98 are located only on one side can be implemented as a double insulation structure by following the structure of FIG.
Next, a generator motor 100 in a power generation state according to a fifth embodiment of the present invention is shown in FIGS. 14 and 15, the circular electric circuit portion 106 of the cylindrical field armature assembly 103 is concentrically fixed to the rotating shaft 120. Similarly, the magnetic field generation unit 104 and the magnetic flux focusing unit 114 are also circular, thereby simplifying the structural complexity of the field armature assembly 63 shown in FIGS. 10 and 11 of the third embodiment. . For example, if the magnet is circular, the forming process is easy, and the magnetic flux concentrating part can be easily drawn by a circular press.
The outer peripheral cylindrical first electrical connection portion 119a is divided into two in the circumferential axis direction, and the gap portion 124 divided into one first electrical connection portion 119a and the other first electrical connection portion 119a is formed by the electrical insulation portion 113. The electrical connector 125, which is electrically separated and fixed and fixed to a fixed object (not shown), generates electromotive force or current while sliding from one divided first electric connection portion 119a to the other first electric connection portion 119a. Connect. As a result, the electromotive force V on the straight line between the electromagnetic induction crossover portion 111 and the electromagnetic non-induction crossover portion 112 is increased as shown in FIG. In the case of power generation, a high counter electromotive force is generated by a stacked stack of ninety-nine-fold series connection in which the first electric connection portion 119a having a cylindrical shape and the second electric connection portion 119b having an inner cylindrical shape are alternately connected to the electric circuit portion 106. In the case of electric drive, a DC electromotive force or a DC current with less magnetic noise is obtained by increasing the supply current density.
15 is a cross-sectional view taken along the line CC in FIG. An electric connector 125 fixed to a fixed portion (not shown) is slidably brought into contact with the outer periphery of the electric circuit portion 106, and a plurality of magnetic flux passage portions 115 magnetically shielded by the magnetic shielding portion 117 on the outer periphery and inner periphery of the electric circuit portion 106. Are arranged equally through the electric circuit portion 106.
When the rotational force F acts in the direction shown in the drawing, the magnetic flux φ is orthogonal to the direction of the rotational force F from the front of the drawing to the rear of the drawing, so that an electromotive force V is generated in the direction of the electrical connector 125 in the electromagnetic induction crossover portion 111. In the electromagnetic non-inductive crossing portion 112 where the electric circuit portion 106 and the magnetic flux passage portion 115 intersect, the electromotive force V and the magnetic flux φ are separated so that the generated electromotive force V does not cancel out.
In addition, when the number of the plurality of magnetic flux passage portions 115 on the inner and outer circumferences of the electric circuit portion 106 is increased, the electromagnetic induction crossover portion 111 and the electromagnetic non-induction crossover portion 112 can be placed on a straight line with respect to the electromotive force V direction. As a result, the electromotive force conversion efficiency is improved.
Next, FIG. 16, FIG. 17, and FIGS. 18A to 18E show the states of two cycles of power generation / charging and discharge / electricity of the generator motor 200 of the sixth embodiment of the present invention. In FIG. 16, field armature assemblies 230 and 231 that are electrically separated and independent from each other are arranged symmetrically about the rotation shaft 220. The state shown in FIG. 16 shows a configuration in which one field armature assembly 230 functions as an electric function using a discharge current, and the other field armature assembly 231 functions as a power generation function for storing a charge. Yes.
Next, the operation sequence of the two cycles will be described. In the first cycle, as shown in FIG. 16, the current collector 240 and the semi-cylindrical electric circuit end 250 of the field armature assembly 230 are in a connected state, and the current collector 241 and the field armature assembly The semi-cylindrical electrical circuit end 251 of the body 230 is in a connected state. Also, the electrode 260a at one end of the externally charged battery 260 shown in FIG. 16 is connected to the current collector 240 by the changeover switch SW1. The other electrode 260b is connected to the current collector 241 by a changeover switch SW2. As a result, the field armature assembly 230 causes the rotating body 223 of FIG. 16 to function as a motor by causing the discharge current I to flow from the capacitor 260, and the CW (clockwise) as shown in FIGS. 18 (A) and 18 (B). ) Direction.
Further, as shown in FIG. 16, the current collector 242 and the semi-cylindrical electric circuit end 252 of the field armature assembly 231 are in a connected state, and the current collector 243 and the field armature assembly 231 are connected. The semi-cylindrical electric circuit end 253 is in a connected state. Further, the electrode 261a at one end of the external uncharged battery 261 in FIG. 16 is connected to the current collector 242 by the changeover switch SW3, and the electrode 261b at the other end of the battery is connected to the current collector 243 by the changeover switch SW4. It is connected to the.
Since the one field armature assembly 230 is electrically driven and rotated in the CW direction when viewed from the right direction in FIG. 16, the other field armature assembly 231 is rotated in conjunction with the power generation state. The electric charge of the conductor due to the generated electromotive force V is charged in the battery 261.
When the rotating body 223 further rotates in the CW direction, neither the current collector 240 nor the current collector 242 shown in FIG. 16, which is electrically driven or generated, is electrically OFF, the current collector 241 and the current collector 243 are OFF, SW1˜ The SW4 is turned off, that is, the state shown in FIG.
Since the rotating body 223 has inertia, when the rotation further proceeds in the CW direction, when the second cycle is entered here, the state becomes as shown in FIGS. 18D and 18E, and the electric state and the power generation state are reversed. That is, this time, the field armature assembly 230 is in an electric state, and the field armature assembly 231 is in a power generation state.
The second cycle is the reverse connection shown in FIG. That is, as shown in FIG. 16, on the one hand, the electrical circuit end 250 of the current collector 242 and the field armature assembly 230 is in a connected state, and the electrical current of the current collector 243 and the field armature assembly 230 is The circuit end 251 is connected.
Also, the electrode 261a at one end of the externally charged battery 261 in FIG. 16 is connected to the current collector 243 by the changeover switch SW3. Further, the electrode 261b at the other end of the battery 261 is connected to the current collector 242 by the changeover switch SW4. As a result, the polarity of the electrode of the battery 261 is reversed. The field armature assembly 230 operates as an electric motor in the second cycle when the discharge current I flows from the capacitor 261, and the rotating body 223 is CW (clockwise) as shown in FIGS. 18D and 18E. ) Direction.
On the other hand, the current collector 240 and the electric circuit end 252 of the field armature assembly 231 in FIG. 16 are connected, and the current collector 241 and the electric circuit end 253 of the field armature assembly 231 are connected. It becomes a state. Further, the electrode 260a at one end of the externally discharged battery 260 shown in FIG. 16 is connected to the current collector 241 by the changeover switch SW1, and the electrode 260b at the other end is connected to the current collector 240 by the changeover switch SW2. Therefore, the polarity of the electrode of the capacitor 260 is reversed.
Since the one field armature assembly 231 is electrically driven and rotated in the CW direction, the other field armature assembly 230 is interlocked and rotated to be in a power generation state in the second cycle. The moving charge of the conductor is charged in the battery 261. By alternately repeating the first cycle and the second cycle, a two-cycle motor generator can be realized.
Here, the identity of the rotation direction as a rotating body by two cycles will be described with reference to FIGS. 18 (A) to 18 (E). The field armature assembly 230 shown in FIGS. 18 (A) and 18 (B) is electrically driven by the discharge of the battery 260 shown in FIG. 16, so that the electromagnetic induction crossover portion 211a shown in FIG. Due to the stress of the orthogonal magnetic field φ from the front side of the drawing to the back side of the drawing, the electric charge due to is received a force F in the left direction of the drawing. Thereby, it rotates in the CW (clockwise) direction according to Fleming's left-hand rule.
On the other hand, in the field armature assembly 231, due to the rotational force F in the CW direction of the field armature assembly 230, the electric charge in the conductor of the electromagnetic induction crossover portion 211 b in FIG. By receiving the stress of the orthogonal magnetic field φ that goes, the electromotive force V is generated in the direction of the arrow according to the Fleming right-hand rule, and the mobile charge is charged in the battery 261 in FIG.
Further, the rotation proceeds in the CW direction, and the state shown in FIG. 18C is electrically OFF. Since this state must be completely OFF, FIG. 17 is a cross-sectional view taken along the line DD in FIG. Two field armature assemblies 230 and 231 are fixed to the rotating shaft 220 as the rotating body 223.
Semi-cylindrical electric circuit ends 250 and 252 respectively connected to the field armature assemblies 230 and 231 are equally inserted and fixed by an electric insulating portion 213, and slide with the current collectors 240 and 242 as shown in the figure, respectively. In contact. As shown in FIG. 17, the gap central angle θg insulated by the electrical insulation portion 213 between the central angle θe of the current collector sliding portion 229 of the current collectors 240 and 242 and the semi-cylindrical electric circuit ends 250 and 252 is: The relationship θg> θe must be satisfied.
Further, as shown in FIG. 16, the other electric circuit end portions 251 and 253 and the current collectors 241 and 243 maintain the same relationship as described above.
At this time, the electrode switch SW1 of the battery 260 and the electrode switch SW2 of the battery 261 in FIG. 16 are in the OFF state. This is also a condition for the next electric reversal operation due to the electric pause.
Further, when the rotation proceeds in the CW direction, the field armature assembly 231 in FIG. 18D and FIG. 18E is in an electric state due to the discharge of the battery 261 in FIG. The electromagnetic induction crossover portion 211b receives a force F in the left direction of the drawing when the electric charge due to the discharge current I receives a stress of an orthogonal magnetic field φ from the front side of the drawing to the back side of the drawing. Thereby, it rotates in the CW (clockwise) direction according to Fleming's left-hand rule.
On the other hand, in the field armature assembly 230, due to the rotational force F in the CW direction of the field armature assembly 231, the electric charge in the conductor of the electromagnetic induction crossover portion 211a in FIG. By receiving the stress of the orthogonal magnetic field φ that goes, an electromotive force V is generated in the direction of the arrow according to Fleming's right-hand rule, and the mobile charge is now charged in the battery 260 of FIG.
Here, it should be noted that the applied voltage Vc of the electric storage devices 260 and 261 during electric driving must be larger than the back electromotive force voltage Vg generated by the armature rotation speed during electric driving. In other words, there is a relationship between the rotational speed of the rotating body, the amount of power generated during half rotation, the amount of charge stored in the capacitor, and the capacity of the capacitor. Moreover, when using it by constant speed rotation speed control at the time of actual use, the electric power generation torque more than generation load torque is required.
To that end, of course, when using mainly the motor, supply the power for replenishment while adjusting the depth of discharge of the external capacitor, or when using mainly the generator, the external drive unit is used as the power generator of the present invention. What is necessary is just to connect and use to the axis | shaft of the electric motor 200. By implementing the present invention, high efficiency can be expected for the relationship between the entire input and output. However, this is a design matter, and what is important is the magnetic circuit design and electric circuit design of the field armature assembly of the present invention and the storage characteristics of the capacitors 260 and 261 so as to maintain the applied voltage Vc> the back electromotive force voltage Vg. Selection becomes important.
In actual use, the electric capacitors 260 and 261 suitable for the above are excellent electric double layer capacitors. The electric double layer capacitor is characterized by extremely fast charge / discharge, so the energy density is small, but the output density is large and the internal resistance is small. However, the disadvantage is that the voltage is as low as 3 to 4 V even in the case of an organic electrolyte.
However, the shortcomings of single pole machines are one of the reasons why it is not popular because there was no power source with low induced voltage and low internal resistance, so the complementary relationship between electric double layer capacitors and single pole machines has been known for some time, The electric drive by charging and discharging from the power generation during one rotation of the generator motor according to the present invention to the electric double layer capacitor is not a conventional voltage power supply, but a high-efficiency charge / discharge as a current power supply which is a disadvantage of both. The relationship between bolts and nuts can now be realized.
Because of the relationship between bolts and nuts, two cycles of charging and power generation can be realized during one rotation. Originally, an electromagnetic conversion motor is called a motor three state, and consists of three states of power generation, electric drive and braking. The technology that generates electricity, moves with electricity, and saves electricity is an old and new technology for the dispersion and fusion of electrical energy.
In addition, what is necessary is just to use a semiconductor switching element at the time of actual use of changeover switch SW1-SW4 of FIG. That is, it is possible to switch the current between the collector and the emitter by ON / OFF of the bipolar transistor, power MOSFET, and IGBT gate current control often used for a DC to AC conversion inverter.
Next, FIG. 19 shows the power generation / charge and discharge / electricity states of the generator motor 300 according to the seventh embodiment of the present invention. FIG. 19 is the same as the sixth embodiment in that the field armature assemblies 330 and 331 that are electrically separated and independent from each other are arranged symmetrically with respect to the axial center. In the case of the sixth embodiment, FIG. There are two-cycle limitations of power generation / charging and discharging / electric motoring during one rotation of the rotating body, and there are limitations on the selection of a capacitor and the design as a motor generator.
Also, if you want to increase the amount of power generation and use it at high output and high speed, there will be a limit. On the other hand, the generator motor 300 of the seventh embodiment can operate without such limitation. The state shown in FIG. 19 shows a configuration in which one field armature assembly 330 functions as discharge / electricity, and the other field armature assembly 331 functions as power generation / charging.
Next, the operation order will be described. As shown in FIG. 19, the current collector 340 and the cylindrical electric circuit end 350 of the field armature assembly 330 are in a connected state, and the electric circuit end 350 is a cylindrical electric circuit end 352. And the rotating shaft 320 are insulated and protected by an electrical insulation unit 313 and connected to an electrical circuit unit 306. The current collector 341 and the cylindrical electric circuit end 351 of the field armature assembly 330 are in a connected state, and the electric circuit end 351 is connected to the cylindrical electric circuit end 353 and the rotating shaft 320. The space is insulated and protected by an electrical insulation unit 313 and connected to the electrical circuit unit 306.
Further, the electrode 360a at one end of the externally charged battery 360 shown in FIG. 19 is connected to the current collector 340 by the changeover switch SW5, and the electrode 360b at the other end is connected to the current collector 341 by the changeover switch SW6. Has been. Accordingly, in the field armature assembly 330, when the discharge current I flows from the capacitor 360, the rotating body 323 as an electric motor has the same current direction and magnetic field orientation φ in FIG. 16 of the sixth embodiment. The rotating body 323 rotates in the CW direction (clockwise) when the rotating shaft 320 is viewed from the right side of the drawing.
As shown in FIG. 19, the current collector 342 and the cylindrical electric circuit end 352 of the field armature assembly 331 are in a connected state. The current collector 343 and the cylindrical electric circuit end 353 of the field armature assembly 331 are in a connected state. Further, the electrode 361a at one end of the external uncharged battery 361 in FIG. 19 is connected to the current collector 342 by the changeover switch SW7. The electrode 361b at the other end of the battery 361 is connected to the current collector 343 by the changeover switch SW8. Thereby, the rotating body 323 of the one field armature assembly 330 is electrically rotated in the CW direction when the rotating shaft 320 is viewed from the right side of FIG. 19, and therefore the other field armature assembly 331 is rotated. Is in a power generation state, and the moving charge of the conductor due to the generated electromotive force V is charged in the battery 361.
The field armature assemblies 330 and 331 shown in FIG. 19 are the same as those in the sixth embodiment in that they are electrically separated and independent from each other. Although the semi-cylindrical electric circuit end and one current collector are shared, in the seventh embodiment, there is no sharing of such an electric circuit unit and current collector, and the electric current including the current collector is included. Thus, the field armature current collecting assemblies 370 and 371 that are completely separated and independent can freely control input and output under common rotation.
Switching between power generation / charge and discharge / electricity is possible as in the description of the sixth embodiment. 19 is switched between the current collectors 340 and 341 by switching the electrodes 360a and 360b of the capacitor 360, and the switch SW7 / SW8 is switched between the current collectors 342 and 343 by switching between the electrodes 361a and 361b of the capacitor 361. Switching is possible.
The capacitors 360 and 361 can use an electric double layer capacitor having a higher capacity, and the secondary battery can also be used as a lithium ion battery or a fuel cell. Further, four field armature assemblies 63 of FIGS. 10 and 11 of the third embodiment are connected in parallel, but this can be connected in series in the seventh embodiment.
For example, when used as a generator, the current collector 340 and the current collector 343 in FIG. 19 are connected, and the current collector 341 and the current collector 342 are used as output terminals, so that they can be connected in series. In other words, depending on the design, the number of fields and armature circuits in the axial circumferential direction can be increased to a plurality of numbers, and an induced voltage corresponding to a high voltage can be secured by stacking multiple layers in the axial direction.
Next, an eighth embodiment of the present invention will be described with reference to FIGS. 20 (A) to 20 (D). The field winding 430 of the field armature assembly 403 shown in FIG. 20A functions as a magnetic field generator. The field winding 430 has two types of shapes. For example, the rectangular winding coil 431 in FIG. 20C uses a permanent magnet for the magnetic field generation unit in FIGS. 10 and 11 of the third embodiment. However, a rectangular winding coil 431 can be used instead of the rectangular magnet. 20D can use, for example, a circular electromagnet winding coil 432 instead of the circular permanent magnets of FIGS. 14 and 15 of the fifth embodiment.
FIG. 20A and FIG. 20B showing the details of part A are schematic diagrams of the structure and cooling system when the field winding is made of a superconducting material. The two field windings 430 are connected such that the same magnetic poles are opposed to each other, and are connected to each other through the conduction hole 445 of the rotating shaft 420 to slide from the contacts 440 at both ends of the rotating shaft 420 to the fixed side. The lead 441 is brought into contact with the child 441 and connected to an external power source or an external load (not shown) from the lead wire 433.
In addition, in order to cool the superconducting field winding 430, the cooling gas is supplied from one liquid nitrogen tank 449, passes through the vent hole 446 of the contactor 440, passes through the conduction hole 445 of the rotating shaft 420, and has a sealed structure. After the field winding 430 inside the field armature assembly 403 is cooled, the field winding 430 passes through the vent hole 446 of the contact 440 on the opposite side of the rotating shaft 420 and is collected in the other liquid nitrogen tank 449. Note that the gap of the fixed-side seal holder 447 that is rotatable by the rotating shaft 420 and the fixed bearing 421 is rotationally sealed with the magnetic fluid 448. The seal holder 447 is a method often used in a vacuum seal or the like by forming a closed magnetic circuit by sandwiching the gap portion between a permanent magnet and a magnetic member. The material of the field winding 430 is, for example, an yttrium-based (Y—Ba—Cu—O) high temperature superconducting material.
Next, a power storage assembly 510 according to a ninth embodiment of the present invention will be described with reference to FIG. 21 (A), FIG. 21 (B), and FIG. 21 (A) and 21 (B) show a power storage assembly that solves the problem of lifetime reliability due to mechanical wear of the fixed-side current collector and the rotary-side electric sliding part that the conventional monopolar machine has. It is a body 510.
The power storage assembly 510 shown in FIG. 21A includes an electrolyte 580 filled in a gap between the rotating electrode body 530 and the fixed electrode body 540 and a capillary seal portion 531 joined to both sides of the electrode for preventing electrolyte leakage. It is configured.
A rotating electrode body 530 is fixedly coupled to both ends of the rotating shaft 520 in FIG. 21A and is electrically connected. A collecting electrode 560 is bonded to the outer peripheral surface of each rotating electrode body 530 by a conductive adhesive, and a polarizable electrode 550 is bonded to the outer peripheral surface of the collecting electrode 560 by a conductive adhesive. A separator 570 is joined to the outer peripheral surface of the polar electrode 550 by a conductive adhesive.
On the other hand, the fixed electrode body 540 is joined to the inner peripheral surface from the outer peripheral side in the order of the collector electrode 560, the polarizable electrode 550, and the separator 570, respectively, similarly to the rotating electrode body 530 by using a conductive adhesive. Yes. The gap between the outer peripheral surface of the rotating electrode body 530 and the inner peripheral surface of the fixed electrode body 540 is filled with an electrolytic solution 580. In this way, the externally connected capacitors 260 and 261 of FIG. 16 of the sixth embodiment and the externally connected capacitors 360 and 361 of FIG. 19 of the seventh embodiment can be charged and discharged in the generator motor. Built-in as the assembly 510 can be realized.
In FIG. 21B, the inner peripheral surface of the rotating electrode body 530 and the outer peripheral surface of the fixed electrode body 540 are reversed between the inner periphery and the outer periphery with the electrolyte solution 580 interposed therebetween. In FIGS. 21A and 21B, a fixed electrode body 540 as a current collector is connected to a field armature assembly 503 and can be charged / discharged. The electrolyte solution between the rotating electrode and the fixed electrode is kept uniform by mutual rotation (movement) between the electrodes, the electrode potential is stabilized, the electrode surface is prevented from being deteriorated, and the life is repeatedly improved. Moreover, it is excellent also as a swelling prevention which is a problem of the electric double layer capacitor.
The electric double layer is an interfacial phenomenon in which the electrolyte surface in contact with the electrode surface forms a double layer of a solvent molecule layer and an ion molecule diffusion layer outside thereof. Since the solvent molecule layer contains specific adsorbed molecules, a potential is generated between the electrode and the electrolytic solution. As a result, the electrode charge is a phenomenon that does not involve the chemical reaction of attraction and repulsion, that is, charge and discharge, due to the interaction of the electrostatic field. Excellent cycle characteristics, high output density, high charge / discharge efficiency, and low internal resistance.
The polarizable electrode 550 accumulates charges using activated carbon made of microcrystalline carbon as a positive electrode and a negative electrode. The collector electrode 560 is preferably a platinum foil because it is intended to be electrically connected to the outside faithfully, but an aluminum foil without an oxide film is preferred because of cost. The polarizable electrode 550 and the collector electrode 560 are joined by a conductive adhesive, but aluminum welding is preferably performed on the joint surface between the polarizable electrode 550 and the collector electrode 560 in order to increase the current collection efficiency.
Separator 570 is involved in self-discharge characteristics and internal resistance, and is tightly interposed between the positive and negative electrodes, for the purpose of preventing electrical short-circuiting and promoting the passage of electrolyte ions, glass fiber, polyolefin, polyamideimide, polyester, polytetra Fluoroethylene (PTFE) is suitable.
Electrolytic solution 580, which is an ionic conductor, is composed of a solvent and an electrolyte. There are an aqueous electrolyte and a non-aqueous electrolyte. The aqueous solution has good rapid charging with sulfuric acid, potassium hydroxide, etc., and the non-aqueous electrolyte. Is an organic tetraethylammonium tetrafluoroborate (tetraethylammonium tetrafluoroborate) as an electrolyte, and a solvent is generally polypropylene carbonate.
In addition, since the rotating electrode body 530 and the fixed electrode body 540 according to the ninth embodiment of the present invention have a rotating seal structure, an ionic liquid is excellent as the electrolytic solution 580. 1-Ethyl-3-methylimidazolium tetrafluoroborate can be used in air atmosphere, is non-crystalline, flame retardant, non-volatile, has a relatively low viscosity, wide potential window, and high conductivity ionic liquid (Normal temperature molten salt) is a kind of cation, such as pyridine type, alicyclic amine type, aliphatic amine type, diethylmethyl 2-methoxymethylammonium tetrafluoroborate, 1-butyl 3-methylimidazolium ion, etc. Has hydrophilicity, hydrophobicity and poor solubility in organic solvents.
FIG. 22 is an overall cross-sectional view showing a power generation / storage state of a generator / motor storage device (generator motor) 500 according to a ninth embodiment of the present invention.
