Abstract:
New permanent magnetic motor utilizing interacting rows of magnets on rotor poles and a main rotor. The rotor poles have rows of permanent magnets with increasing numbers of magnets per row. The main rotor has magnets and an electro-magnet. Magnets are arranged in opposite direction and polarity on the rotor poles in relation to the main rotor. Magnetic attraction of rotor poles to the main rotor magnets results in a progressive magnetic rotational action producing rotational output. The motor is started, operated and stopped utilizing an electronic controller. Constant rotation is maintained by pulsing the electro-magnet with the controller synchronized to a feedback sensor located on the main rotor shaft.

BACKGROUND OF THE INVENTION 
       [0001]    1. Technical Field 
         [0002]    This invention relates to magnetic motors in general, and more particularly to a motor having multiple rotors with permanent magnets which interact with one another to produce a mechanical output. 
         [0003]    2. Description of Prior Art 
         [0004]    Magnetics are well-known in the art and have been developed and used for many years. Examples of such can be seen in U.S. Pat. Nos. 3,686,524, 3,935,487, 4,358,693, 5,448,116, 7,898,135, and U.S. Publications 2003/0062785, 2008/0122299, and U.S. Publication 2010/0219703. 
         [0005]    In U.S. Pat. No. 3,686,524, a permanent magnet motor is disclosed having permanent magnets housed in a casing of magnetically safe material; an armature about the permanent magnets with a dimensional ratio therebetween. 
         [0006]    U.S. Pat. No. 3,935,487 illustrates a permanent magnetic motor that utilizes a moveable magnetic shield interposed between magnets when they are adjacent one another, and moving to then expose shield magnet as a moveable magnetic shield passes by. 
         [0007]    U.S. Pat. No. 4,358,693 claims a permanent magnetic motor having multiple stators and rotators with each stator having an electro-magnetic coil and each contacting rotor permanent magnets with their magnetic poles in alternate polarity. 
         [0008]    U.S. Pat. No. 5,448,116 discloses a linear magnetic motor with rotational output having multiple stationary electro-magnets coupled to a power source. 
         [0009]    U.S. Pat. No. 7,898,135 shows a hybrid permanent magnetic motor with permanent magnets placed in a magnetically attracting manner and inter-dispersed between control coils. The control coils are energized to create a flux opposing the flux of the permanent magnets and to create rotational torque on the poles of the salient pole rotor before those poles align with the poles of the energized control coil stator segment. 
         [0010]    U.S. Publication 2003/0062785 defines a MagnoDrive “magnetic motor” that has a stator cylindrical magnet and a rotor assembly that does not require any external power input. The design requires large magnets with all South Poles on the inside of a stator and South Poles on the rotor, defining an alleged workable motor output. 
         [0011]    U.S. Publication 2010/0219703 illustrates a magnetic motor having a piston and cylinder configuration with multiple electro-magnetic coils around the cylinder for selective activation, pulling the piston up and down within the cylinder. 
       SUMMARY OF THE INVENTION 
       [0012]    A magnetic motor that utilizes multiple permanent magnets positioned on at least two rotors in an adjacent magnetic communication with one another. Multiple rows of permanent magnets on each rotor in magnetic polar opposition sequence engage imparting rotational input force therebetween. A single electro-magnet on a main rotor is pulsed by a controller so as to maintain progressive magnetic rotation output synchronized by a feedback sensor. Magnet rows on each rotor are of an ascending number, is defining the rotational magnetic sequence of opposing pole engagement through the rotor output imparted thereby.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0031]    Referring to  FIG. 1  and  FIG. 14  of the drawings, a progressive magnetic rotational motor  10  of the invention is of a direct current DC permanent magnetic motor having multiple permanent magnet pole rotors  11 A,  11 B,  11 C,  11 D and a main rotor  12  consisting of permanent magnets and a single electro-magnet. The rotor poles  11  are arranged for magnetic interaction with the main rotor  12 . All of the rotors have a plurality of magnetic pole oriented permanent magnets  13 , which are positioned annularly and longitudinally thereon in a specific numerical order and magnetic pole orientation as will be described in detail hereinafter. 
         [0032]    The main rotor  12  has an electro-magnetic coil  14  that is pulsed on and off by an electronic controller EC to provide electro-magnetic input at a critical point in their representative rotational positioning during operation to start, maintain, or stop rotation. The magnetic induced rotation mechanical force is indicated by directional arrows D on a drive output shaft  32  of the main rotor  12  and rotor poles  11 A,  11 B,  11 C and  11 D. 
         [0033]    The main rotor  12  has interlinking positional gearing  33  with the foregoing magnetically driven rotor poles  11 A,  11 B,  11 C and  11 D, as will be described in greater detail hereinafter. 
         [0034]    Each of the respective rotor poles  11 , best seen in  FIGS. 1 and 3  of the drawings, is in this example constructed of a plurality of sub-assembly disks  17 A,  17 B,  17 C,  17 D,  17 E,  17 F,  17 G,  17 H which are made in this example from formed powder metal according to well-known and accepted manufacturing processes. Powder metal fabrication processes are used due to its magnetic properties and ease of formation. 
         [0035]    Each disk  17  is identical, having a keyed center aperture  18  and a plurality of magnet and weight mounting notches  19  in annular space-relation to one another about its perimeter edge surface  17 H, best seen in  FIGS. 4 and 5  of the drawings. A pair of parallel spaced assembly apertures  16  is formed within the field of the disk  17  in aligned space-relation with the central keyed opening  18 . Each of the multiple disks  17 A,  17 B,  17 C,  17 D,  17 E,  17 F,  17 G,  17 H which are required to form a rotor pole  11  have one or more permanent magnets  13  secured within the respective mounting notches  19  in rotational numerical sequence as illustrated in broken lines in  FIGS. 4 and 5  of the drawings, with one magnet  13  and in  FIGS. 6 and 7  with two magnets  13 . The remainder of open notches  19  in each disk, have a balance weight  20  of an equal dimension and mass to that of the magnet  13 , secured within to provide rotational balance to the disk  17 . Each of the magnets  13  is arranged in reverse magnetic pole (North) (South) orientation to its adjacent magnet as seen in  FIGS. 6 and 7  of the drawings, and graphically in operational  FIGS. 14, 15 , and  16  of the drawings. 
         [0036]    The multiple disks  17 A,  17 B,  17 C,  17 D,  17 E,  17 F,  17 G,  17 H, each with a different ascending number of permanent magnets  13  beginning with one magnet  13  on disk  17 H and ending with eight magnets  13  on disk  17 A thereabout. 
         [0037]    The disks  17 A,  17 B,  17 C,  17 D,  17 E,  17 F,  17 G,  17 H are assembled together by a pair of threaded retainment fastener rods  21  through the assembly aperture  16  and corresponding engagement nuts  23  forming a single rotor pole  11  as seen in  FIG. 3  of the drawings. Given their keyed aligned orientation and the sequential positioning of the magnets  13  and corresponding balance weights  20 , each of the rotor poles  11  will have in effect longitudinal rows of permanent magnets  13  of varying lengths in progressive numerically ascending manner, as illustrated graphically in  FIG. 17  of the drawings. Each of the longitudinal extending rows of magnets will be of the same magnetic pole (North) or (South) respectively. 
         [0038]    Referring now to  FIG. 1  and  FIG. 2  of the drawings, the main rotor  12  can be seen, which is comprised of multiple main rotor disks  22 A,  22 B,  22 C,  22 D,  22 E,  22 F,  22 G,  22 H as seen in  FIG. 8  and  FIG. 9  of the drawings. Each of the disks  22  are identical to the sub-assembly rotor pole disk  17  as hereinbefore described, with a plurality of annularly spaced notches  19  with the addition of electro-magnetic mounting fitting  24  in place of one of the mounting notches  19 . The electro-magnetic mounting fitting  24  has a pair of coil receiving notches  25  around which an electro-magnetic coil  14  winding is positioned when assembled on the main rotor  12 . The remaining magnetic and weight mounting notches  19  have a sequential arrangement of permanent magnets  13  and balance weights  20  with the same numerical ascending magnets  13  and corresponding number of descending weights per disk, as seen in  FIG. 2  of the drawings. It will be evident that the assembled disks  22 A,  22 B,  22 C,  22 D,  22 E,  22 F,  22 G,  22 H also have a keyed center aperture  18  and assembly receiving apertures  16  for corresponding engagement of threaded rods  21  and fastener nuts  23  to secure the plurality of disks  22  together, forming the main rotor  12 . 
         [0039]    Once assembled, a coil cover plate  28  is secured over the exposed portion of the electro-magnetic coil  14  with screws  27 , as illustrated in  FIG. 2  of the drawings. 
         [0040]    In this example chosen for illustration, the progressive magnetic rotational motor  10  utilizes multiple rotor poles  11 A,  11 B,  11 C,  11 D arranged for magnetic drive engagement about the central main rotor  12 , as seen in  FIGS. 1, 13  and  FIG. 14  of the drawings in a support housing  29  with corresponding keyed support shafts  30  with individual shaft bearing assemblies  31  to support same. 
         [0041]    The main rotor  12  is correspondingly assembled as noted on a keyed drive output shaft  32  with respective bearing assemblies  31  within the support housing  29 . 
         [0042]    The rotational position timing gears  33  are positioned on the respective keyed shafts  30  and drive shaft  32  inter-engaged to one another to prevent the respective rotors from slipping out of synchronization. 
         [0043]    Referring now to  FIGS. 14, 15, and 16  of the drawings, the rotor pole permanent magnets  13  positioning is illustrated with aligned magnet numbers in longitudinal rows, such as rotor pole  11 A having one magnet (North Pole) and main rotor  12  having one magnet (South Pole) and so on. Each of the rotor poles  11 A,  11 B,  11 C,  11 D have the same overall number of magnets  13  arranged in respective longitudinal row of corresponding numbers from one magnet to eight magnets, illustrated graphically in  FIG. 17  of the drawings, for longitudinally defined rows A, B, C, D, E, F, G, H respectively. The main rotor  12  only has seven longitudinal magnet rows A, B, C, D, E, F, G, with the electro-magnet EM defining a longitudinal row H′, as seen graphically in  FIG. 18  of the drawings. 
         [0044]    It will thus be seen that the arrangements of the magnets  13  in opposite magnetic pole direction on the respective sub-assemblies disks  17  and  22  annular rows that they will therefore effectively rotate due to the magnetic pole orientation once started by the electro-magnet EM in a sequential function; therefore achieving the hereinbefore described progressive magnetic rotation and provide mechanical rotational output to the drive rotor shaft  32 . 
         [0045]    The electro-magnet EM as noted is sequentially timed for activation required for operation is determined by an electronic controller EC indicated in broken lines in  FIG. 1  and  FIG. 12  of the drawings. A feedback sensor S is required and mounted on the back of the magnetic motor  10  comprising a hall effect pickup  35  and magnetic timing wheel  36  used in this example. It will be evident that other known feedback devices can be used, such as encoders, as is well-known and understood within the art. 
         [0046]    The magnetic timing wheel  36  in this example, as seen in  FIG. 10  and  FIG. 11  of the drawings, has multiple timing magnets  37  positioned in space annular relation thereon, with the hall effect pickup  35  seen in  FIGS. 1  and  12  of the drawings, positioned to synchronize the rotation of the magnetic timing wheel  36  with the main rotor drive shaft  32 . Given the orientation of the timing magnet  37  this happens four times per revolution and is in communication with the electronic controller EC for effective pulse activation of the electro-magnet EM. An electric power transfer slip ring  38  with contact brushes  39  provide an electrical connection between the electronic controller EC and the rotating electro-magnet EM, as is typical within the art. 
         [0047]    The operational function of the magnetic motor  10  by the permanent magnet orientation and engagement is graphically illustrated for better understanding in  FIG. 14 ,  FIG. 15 , and  FIG. 16 , wherein the magnet  13  designated N 1  (North Pole) on the rotor pole  11 A and the magnet  13  designated S 1  (South Pole) on the main rotor  12  are attracted to one another defined as one magnetic set each. The magnet row, having two magnets  13 , defined as S 2  (South) and N 2  (North) on the respective rotors, rotationally overtake the “one set” magnets in a progressive matter thus inducing rotation thereto. This sequential overtaking of the next magnet set, which is of increasing magnet numbers, provides rotation between the respective multiple rotor poles  11 A,  11 B,  11 C,  11 D and the main rotor  12  rotating therefore the drive shaft  32  providing useable mechanical output OP, as seen in  FIGS. 1 and 18  of the drawings. 
         [0048]    Referring now to  FIG. 15  of the drawings, the progressive rotation of the rotor pole  11  and main rotor  12  is illustrated wherein the rotor pole  11 A eight magnets  13  designated as numeral S 8  (South Pole) are approaching the electro-magnet EM of the main rotor  12 . The hall effect pickup  35  generates a signal induced from the magnets  37  on the magnetic timing wheel  36  to the electronic controller EC. This in turn activates a source of DC power, pulsing same to the electro-magnet EM through the hereinbefore described power transfer slip ring brush assembly  38  with contact brushes  39  and energizes the electro-magnet EM into a magnetic North Pole, equal in strength to that of the eight approaching rotor pole  11 A South Pole S 8  magnets designated illustration in  FIG. 17  as row H of the longitudinal aligned magnets with the magnetic poles therefore attracting to one another. 
         [0049]    Referring now to  FIG. 16  of the drawings, the rotor pole rotational progress sequence shows that the rotor pole  11 A South Pole S 8  is now facing the energized electro-magnet EM. At this point in the operational sequence, the electronic controller EC de-energizing the electro-magnet EM, thus collapsing the field. This changes its polarity from North to South, which therefore repels the rotors back to the first defined magnet set of one. It will be evident that this action restarts the rotational cycle and the magnetic motor  10  continues to run. It will be seen that the number of energized electro-magnet pulses are determined by the number of rotor poles used, which in this example is four; thus four pulses per revolution are required. 
         [0050]    The magnetic motor  10  will run at constant speed, which depends on the design of the motor and can be varied slightly by the effective feedback timing as described. 
         [0051]    To stop the magnetic motor  10 , the electro-magnet EM is de-energized, at which point the motor  10  will stop with the respective rows of seven magnets facing one another on any one of the rotor poles  11  and main rotor  12 . 
         [0052]    Correspondingly, to start the motor  10 , the electro-magnet EM is initially energized using a separate starter circuit SC indicated generally by broken lines and the electronic controller EC with the number of strong starter pulses corresponding to the rotor pole for one revolution, after which the hereinbefore described pulsing is engaged to maintain the rotation.
