BACKGROUND OF THE INVENTION

Field of the Invention

Embodiments of the present invention generally relate to an apparatus and method of providing electrical energy harnessed from electrical current pulses. Specifically, the apparatus relates to the use of an electric pulse motor and an electromagnetic generator to generate electric power.

Description of the Related Art

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most motors operate through the interaction between an electric motor's magnetic field and winding currents to generate forces within the motor. A pulse motor uses width modulation of each pulse to control rotation speed of the pulse motor. On the other hand, conversion of mechanical energy into electrical energy is generally done by an electric generator. Generally, an electric motor and an electric generator are independent devices and a user cannot use a motor as a generator, or use a generator as a motor.

Conventional flywheel rotor systems are commonly used for energy storage and electrical power converting and regeneration by coupling with a separate electrical generator. They are also used for mechanically smoothing electrical power output. However, flywheel systems have not been developed to generate electrical power directly and in large quantity.

Electromagnets have been used together with electric motors and electric generators to generate and store electric power. An electromagnet generally consists of a coil of insulated wire wrapped around a magnetic iron core. The iron core can be made of a ferromagnetic material to increase the magnetic field created. The magnetic iron core concentrates the magnetic flux of the magnetic field and makes the electromagnet a more powerful magnet.

Electric motors coupled with electromagnets have the problems of generating dragging forces on the rotors of the motors as permanent magnets interacting with iron cores of the electromagnets. The dragging forces make the rotors difficult to move or start up. Flywheel-like electrical motors or generators usually only have one rotor with a rotating shaft, or several rotors that spin on the same direction, which cause “precession” problem of the rotating shaft. The precession is a change in the orientation of the rotational axis of a rotating body. The precession can cause shaking of the shaft, which in turn can produce noises and abrasive wear of the shaft and support. The precession can also cause the rotors to be less efficient. Therefore, there is a need for a novel method and apparatus to use a flywheel electromagnet system to drive a rotor on a shaft and generate large amount of electrical power.

SUMMARY OF THE INVENTION

The present invention generally provides an apparatus of a flywheel electromagnet system and a method thereof to use balanced electromagnetic forces to drive one or more rotors on a fixed shaft and generate large amount of electrical power. The invention aim to provide a novel flywheel type electromagnet system where a shaft supporting the flywheel type electromagnet system is not rotating while the flywheel is rotating by itself to act as a rotor and generate large amount of electrical power.

In one embodiment, an electromagnetic power generator device for generating electric power includes a non-rotating shaft attached to a support frame and at least one flywheel rotor assembly. The flywheel rotor assembly includes a circular ring, a circular nonferrous outer frame coaxially attached to the circular ring and positioned on an outer circumference of the circular ring, a circular nonferrous inner frame attached coaxially to the circular ring and positioned on an inner circumference of the circular ring, where the circular nonferrous outer frame comprises one or more external permanent magnets positioned outwardly and the circular nonferrous inner frame comprises one or more internal permanent magnets positioned inwardly.

The flywheel rotor assembly also includes a circular nonferrous plate, where the circular ring, the circular nonferrous outer frame, and the circular nonferrous inner frame are attached to a first side of the circular nonferrous plate and enclosing an outer circumference of the circular nonferrous plate. The flywheel rotor assembly further includes a bearing having a first centered hole where the nonrotating shaft passes through, where the bearing is positioned within a center portion of the circular nonferrous plate.

The electromagnetic power generator device also includes at least one input driver plate assembly which is coupled to the flywheel rotor assembly via the non-rotating shaft penetrating through the first centered hole of the bearing of the flywheel assembly and a second centered hole of the input driver plate assembly, and where the input driver plate assembly comprises one or more input driver coil assemblies arranged radially apart and attached on a first side of the input driver plate assembly. Each input driver coil assembly includes an iron core having a first end and a second end, and an input driver permanent magnet attached to the first end of the iron core, where the iron core is wrapped around with input driver coils from the first end to the second end.

In another embodiment, an electromagnetic power generator device for generating electric power is provided and includes a non-rotating shaft attached to a support frame, one or more flywheel rotor assemblies, and one or more input driver plate assembly which is coupled to the flywheel rotor assembly via the non-rotating shaft penetrating through the first centered hole of the bearing of the flywheel assembly and a second centered hole of the input driver plate assembly.

In still another embodiment, a method for generating electric power is provided and includes applying an initial start-up force to rotate a flywheel rotor assembly, triggering an optical sensor switch positioned on an input driver plate assembly, and generating an electric current through the input driver coils of an input driver coil assembly to generate a magnetic field. The method also includes generating a magnetic flux amplification by providing an attraction force of the magnetic field generated from the input driver coil assembly to attract the internal permanent magnets positioned inwardly apart on a circular nonferrous inner frame that is attached coaxially on an inner circumference of a circular ring of the flywheel rotor assembly, and providing a repulsion force from the input driver permanent magnet to repulse the internal permanent magnets and counterbalance the attraction force of the magnetic field where a neutral magnetic flux gap distance “D” is kept between the second end of the iron core and an inner edge of the circular nonferrous inner frame of the one flywheel rotor assembly to balance the attraction force and the repulsion force, wherein the internal permanent magnets and the input driver permanent magnets are positioned to face and pass each other freely even having the same magnetic polarity.

The method further includes generating a controlled magnetic flux pulse force from the one or more input driver coil assemblies of the input driver plate assembly to rotate the flywheel rotor assembly at a high rotating speed without hindrance, generating electric power by generating an electric current from the magnetic field of external permanent magnets positioned outwardly apart on a circular nonferrous outer frame that is attached coaxially on an outer circumference of the circular ring of the flywheel rotor assembly, and collecting electric power by an electricity output assembly having one or more output coils.

DETAILED DESCRIPTION

The present invention generally provides an apparatus of a flywheel electromagnet system and a method thereof to use balanced electromagnetic forces and small amount of an input power to drive one or more rotors on a fixed shaft and generate large amount of electrical power. The invention is not an energy storage system but aim to provide a novel approach to use a small amount of input power to drive a flywheel to enable the flywheel to generate a large amount of electrical power directly without a separate electrical generator as in the conventional flywheel energy storage system to retrieve stored energy. As compared to conventional flywheel, embodiments of the invention provide a novel flywheel type electromagnet system where a shaft supporting the flywheel type electromagnet system is not rotating while the rest of the flywheel is rotating so as to function as a rotor to generate power. By spinning the rotor at high speed, current generated from output coils can be collected, and electric power is generated.

FIG. 1Ais a three-dimensional view of an electromagnetic power generator device100, in accordance with some embodiments of the invention. The electromagnetic power generator device100generally includes a flywheel rotor assembly200, an input driver plate assembly300, an input power source402, and an electricity output assembly500. In one embodiment, the input power source402is used to provide an input power or energy to the input driver plate assembly300. For the purpose of clarity of the drawings, some electrical wires, which are shown inFIG. 4, are not shown inFIG. 1AandFIG. 1B. In another embodiment, the input driver plate assembly300is used to drive the flywheel rotor assembly200to generate rotational speed and generate electric energy, which can be extracted and output by the electricity output assembly500.

In still another embodiment, the electromagnetic power generator device100is supported on a shaft270, which is positioned non-rotatory within the flywheel rotor assembly200of the electromagnetic power generator device100. For example, the shaft270of the electromagnetic power generator device100may be supported on a support frame660or any other types of a suitable support structure.

The flywheel rotor assembly200generally includes a circular ring250and a circular nonferrous plate280on one side of the circular ring250, the side not shown inFIG. 1A, but is shown inFIG. 2. The outer portion of the circular ring250is covered by a circular nonferrous outer frame210, and the inner portion of the circular ring250is covered by a circular nonferrous inner frame220. In one embodiment, the circular nonferrous outer frame210of the flywheel rotor assembly200is positioned to the outer circumference of the circular ring250, and the circular nonferrous inner frame220is positioned to the inner circumference of the circular ring250.

In another embodiment, the circular nonferrous outer frame210is coaxially attached to the circular ring250. In yet another embodiment, the circular nonferrous inner frame220is also coaxially attached to the circular ring250. In some embodiments, the circular nonferrous outer frame210can be formed from a cylinder the shape to surround the outer circumference of the circular ring250. The circular nonferrous outer frame210can be made from a metal material, such as aluminum or any other suitable metal materials, and can have a diameter “D” of about 4 inches or larger, for example, between about 5 inches and about 15 inches, such as about ten (10) inches. The circular nonferrous inner frame220can be made from a metal material, such as aluminum or any other suitable metal materials, and can have a radius “R2” (shown inFIG. 3C) of about 1.5 inches or larger, for example, between about 2 inches and about 6 inches, such as about 4.5 inches. Other dimensions and sizes can also be used.

One embodiment of the invention provides that the circular nonferrous outer frame210include a plurality of external permanent magnets230positioned spatially apart and outwardly along the outer circumference of the flywheel rotor assembly200. In one example, the flywheel rotor assembly200may include two or more external permanent magnets230, such as four (4) or more external permanent magnets230, e.g., about twelve (12) or more external permanent magnets230, or about twenty four (24) or more external permanent magnets230, etc.

In another embodiment, the circular nonferrous inner frame220is contemplated to include a plurality of internal permanent magnets240positioned spatially apart and inwardly along the inner circumference of the flywheel rotor assembly200. In one example, the flywheel rotor assembly200may include two or more internal permanent magnets240, such as four (4) or more internal permanent magnets240, e.g., about six (6) or more internal permanent magnets240, about twelve (12) or more internal permanent magnets240, or about twenty four (24) or more internal permanent magnets240, etc.

As shown inFIG. 1A, the electricity output assembly500is positioned adjacent to the flywheel rotor assembly200. The electricity output assembly500includes one or more output coils510supported on a coil support520. The rotation of the external permanent magnets230on the flywheel rotor assembly200are used to generate an electrical current in the electricity output assembly500. As the flywheel rotor assembly200rotates around the shaft270, the speed of the rotation generates the cutting of the magnetic flux from the external permanent magnets230, resulting in the generation and collection of electrical current by the output coils510of the electricity output assembly500. The electrical current is generated by the passing of the external permanent magnets230across the output coils510of the electricity output assembly500. In one embodiment, the shape of the output coils510matches the shape of the external permanent magnets230to increase the efficiency of collecting electric power by the output coils510.

In general, the circular ring250of the flywheel rotor assembly200is used to provide weight to the flywheel rotor assembly200and thus may be made of a heavy weight materials in order to increase the amount of energy generated and/or stored by the electromagnetic power generator device100. For example, the circular ring250may be made of a metal material, such as lead, stainless steel, and other metal materials, among others. In one example, the circular ring250may have radius “R1” (shown inFIG. 3C) of about 2.5 inches or larger (e.g., between about 5 inches and 10 inches, such as 5 inches), a width “W” of about 0.25 inch or larger, (e.g., about 0.75 inch or larger, such as between about 1 inch and about 3 inches) and a thickness “T” of about 0.1 inch or larger (e.g., between about 0.25 inch and about 1 inch). However, the dimension of the circular ring250is not limiting and can be scaled up or down accordingly.

In one example, the circular nonferrous outer frame210of the flywheel rotor assembly200includes eighteen (18) external permanent magnets230, six (6) internal permanent magnets240. In another example, the shape of the external permanent magnets230is a cuboid and each external permanent magnets230may be approximately 50 mm×15 mm×5 mm and have an approximate magnetic force of about twenty one hundred (2100) G-force. The circular nonferrous outer frame210is used to provide house the external permanent magnets230to the flywheel rotor assembly200and thus may be made of any nonferrous nonmagnetic material. For example, the circular nonferrous outer frame210may be made of aluminum, or any other suitable materials, such as lead, stainless steel, and other metal materials, among others.

As another example, each internal permanent magnet240may be approximately 15 mm×15 mm×5 mm and have an approximate magnetic force of thirty one hundred (3100) G-force. Other number, shapes and dimensions of the external permanent magnets230and the internal permanent magnets240can also be used and adjusted accordingly. The circular nonferrous inner frame220is used to provide house the internal permanent magnets240to the flywheel rotor assembly200and thus may be made of any nonferrous nonmagnetic material. For example, the circular nonferrous inner frame220may be made of aluminum, or any other suitable materials, such as lead, stainless steel, and other metal materials, among others.

FIG. 1Bis a three-dimensional partial exploded view of the electromagnetic power generator device100, in accordance with some embodiments of the invention. As shown inFIGS. 1A and 1B, the input driver plate assembly300is coupled to the flywheel rotor assembly200, such as being positioned to fit within the inner circumference of the circular ring250of the flywheel rotor assembly200.

In the example shown inFIG. 1B, the input driver plate assembly300includes a mounting plate310and at least one input driver coil assembly320positioned on one side of the mounting plate310, the side that faces flywheel rotor assembly200. The number of input driver coil assembly320that can be mounted on the mounting plate310can varied, and can be two or more input driver coil assemblies320(e.g., four, six, eight or more input driver coil assemblies320). The mounting plate310of the input driver plate assembly300includes a centered hole318which the shaft270can pass through. The mounting plate310may have radius “R3” (shown inFIG. 3C) of about 2 inches or larger (e.g., between about 2.5 inches and 10 inches, such as 3 inches).

FIG. 2is a planar side view of the flywheel rotor assembly200, viewed from a side opposite of the input driver plate assembly300. As shown inFIG. 2, the flywheel rotor assembly200includes the circular ring250, the circular nonferrous plate280, and a bearing260. In one embodiment, the bearing260is positioned within a center portion of the circular nonferrous plate280and is designed to allow the free rotation of the flywheel rotor assembly200around the shaft270via a centered hole268of the bearing260.

In another embodiment, the circular ring250, the circular nonferrous outer frame210, and the circular nonferrous inner frame220are attached to a first side (the first side that is viewed and shown inFIG. 2) of the circular nonferrous plate280. In addition, the circular ring250, the circular nonferrous outer frame210, and the circular nonferrous inner frame220are positioned to enclose an outer circumference of the nonferrous plate280.

The circular nonferrous plate280may have a diameter of about 5 inches or larger, such as about 8 inches or larger. The circular nonferrous plate280adds to the total overall mass of the flywheel rotor assembly200and thus to the energy that can be generated and stored. Eighteen external permanent magnets230on the circular nonferrous outer frame210are shown inFIG. 2.

In one example, the outer diameter of the bearing260may be about two (2) inches and the inner diameter of the centered hole268of the bearing260may be about one (1) inch when the diameter of the circular ring250is about nine (9) inches. The size and dimension of the bearing260can be adjusted accordingly.

As shown inFIG. 2, a reflective object290can be positioned on one or more surfaces of the internal permanent magnets240. The reflective object290is used together with an optical sensor switch360(shown inFIG. 3B) positioned next to at least one input driver coil assembly320.

Referring back toFIG. 1B, in one embodiment, the electromagnetic power generator device100is assembled by passing the shaft270through the centered hole268of the bearing260within the flywheel rotor assembly200and then through the centered hole318of the mounting plate310within the input driver plate assembly300. In the example ofFIG. 1B, six (6) input driver coil assemblies320are mounted on the mounting plate310. Each input driver coil assembly320may include an input driver permanent magnet350and input driver coils330. In one embodiment, the first side of the circular nonferrous plate280of the flywheel rotor assembly200faces a side of the input driver plate assembly300, the side having a number of input driver coil assemblies320.

FIG. 3Ashows one example of the input driver coil assembly320. Each input driver coil assembly320is composed of an iron core340having a first end and a second end, where the input driver permanent magnet350is attached to the first end of the iron core340. In addition, the input driver coils330are wrapped around the iron core340from its first end to its second end. The length of the iron core340is shown as “L1”. The input driver permanent magnet350, input driver coils330and the iron core340are assembled to form an electromagnet construct. In one example, the input driver permanent magnet350is approximately 15 mm×15 mm×5 mm in size and has an magnetic force of about twenty one hundred (2100) G-force. As an example, the iron core340may be about 8 mm×8 mm with a length L1 of about 50 mm and has about twelve hundred (1200) windings of 30 AWG wire.

FIG. 3Bshows an example of the input driver plate assembly300, viewed from one side of the input driver plate assembly300facing the flywheel rotor assembly200. In the example ofFIG. 3, the input driver plate assembly300includes six (6) input driver coil assemblies320positioned inwardly apart and radially at an angle “α”. In one embodiment, the angle “α” is ranged from zero to 90 degree. In one example, the angle “α” is zero degree. In another example, the angle “α” is 45 degree.

InFIG. 3B, at least one optical sensor switch360is positioned next to at least one input driver coil assembly320. The optical sensor switch360senses radiation reflected by the reflective object290on the surface of at least one internal permanent magnet240when electromagnet force from the input driver coil assembly320and the internal permanent magnets240are aligned to trigger a controlled magnetic flux pulse.

FIG. 3Cillustrates coupling the input driver plate assembly300within the circular ring250of the flywheel rotor assembly200where one example of the input driver coil assembly320is shown to be positioned radially at the angle “α” of zero degree and aligned with one example of the internal permanent magnet240. At the angle “α” of being zero degree, the first end of the input driver coil330is positioned at a radius of “R4” and the second end of the input driver coil330is positioned at edge of the mounting plate310(about the radius of “R3” of the mounting plate310) from a radius center point of the mounting plate310. Since the length of the iron core340is shown as “L1”, thus at the angle “α” of zero degree, R3 equals to L1 plus R4. The radius “R1” of the circular ring250is adjusted to include the thickness “T” of the circular ring250and the radius “R2” of the circular nonferrous inner frame220.

FIG. 3Dshows one example of positioning at least one input driver permanent magnet350within the input driver plate assembly320relative to at least one internal permanent magnet240within the circular nonferrous inner frame220. In one embodiment, there is a gap distance “D” between the radius “R2” of the circular nonferrous inner frame220and the radius “R3” of the mounting plate310, where D equals to R2 minus R3. In one example, the R1 is about 5 inches, R2 is about 3.5 inches, and R3 is about 3 inches, such that D is about 0.5 inch.

In another embodiment, the mounting plate310of the input driver plate assembly300is positioned within the circular nonferrous frame220of the flywheel rotor assembly200in order to align the electromagnet force of at least one driver coil assembly320with at least one internal permanent magnets240within the circular nonferrous frame220of the flywheel rotor assembly200.

In still another embodiment, the internal permanent magnets240on the circular nonferrous inner frame220of the flywheel rotor assembly200and the input driver permanent magnets350on the input driver coil assemblies320of the input driver plate assembly300are positioned to face and pass each other in the same magnetic polarity. As a result, each input driver coil assembly320on the input driver plate assembly300is adjusted to a position where attraction forces of the internal permanent magnets240towards the iron cores340of the driver coil assemblies320and repulsion forces generated between two same polarity magnets240and350, can be balanced out. The position is optimized such that the second end (with a radius of R3) of the iron core340of the input driver coil assembly320is kept at the distance “D” from an inner edge (with a radius of R2) of the circular nonferrous inner frame220of the one flywheel rotor assembly200. The distance “D” equals to R2 minus R3. In one example, the distance “D” between the internal permanent magnets240and the tip of the input driver coils330, is one eighteenth of an inch or larger, such as about one sixteenth of an inch or larger, or about 0.25 inches or larger, e.g., between about one sixteenth of an inch and one inch, or between about 0.25 inch and about 0.5 inch, e.g., about 0.375 inch.

Not wishing to be bound by theory, it is contemplated that when an electric potential is applied across the ends of the input driver coils330, a current flows through the input driver coils330and generates a magnetic field that is greatly enhanced by the presence of the iron cores340and the input driver permanent magnets350. The generated magnetic field from the input driver coil assemblies320provides powerful forces by interacting with the internal permanent magnets240to accelerate or maintain the spinning speed of the flywheel rotor assembly200. In order to effectively accelerate or maintain the spinning speed of the flywheel rotor assembly200, the pulse forces from the input driver plate assembly300have to be applied resonance of the rotation of the flywheel rotor assembly200. In some embodiments, the input driver permanent magnet350is attached to the iron core340such that the magnetic polarity of the input driver permanent magnet350in contact with the iron core340is the same polarity as the polarity of the passing internal permanent magnet240closest to the iron core340. The input driver permanent magnet350counteracts the attraction of the passing internal permanent magnet240towards the iron core340, thus minimizing and essentially eliminating the rotating drag of the flywheel rotor assembly200. This makes the flywheel rotor assembly200easy to start and rotate.

FIG. 4illustrate one example of a pulse driver circuit400in accordance with one or more embodiments of the invention. The pulse driver circuit400is connected electrically to the input power source402and functions to only allow pulsed current to pass when the driver coil assemblies320and internal permanent magnets240are aligned. In some embodiments, a switch, such as the optical sensor switch360(e.g., Fairchild Reflective Opto-Transistor Model QRD 1114) shown inFIG. 3B, can be used.

The optical sensor switch360includes an infrared emitting diode and a detector that mounted side by side in a housing. The optical sensor switch360works by using the detector to detect radiation emitted from the infrared emitting diode and reflected by the reflective object290. The optical sensor switch360is positioned at the same arrangement as a driver coil assembly320in such a manner to allow the detector to be aligned with the reflective object290on the surface of an internal permanent magnet240. The detector senses the radiation reflected by the reflective object290, and triggers a controlled magnetic flux pulse to be applied to the driver coil assemblies320.

In one embodiment, the optical sensor switch360is electrically connected to the pulse driver circuit400. In another embodiment, the optical sensor switch360is positioned close to at least one of the input driver coil assemblies of320of the input driver plate assembly300. The pulse driver circuit400can have some parts separated from or mounted onto the input driver plate assembly300.

In general, the pulse driver circuit400includes a pulse generation circuit, a plurality of the input driver coils330, and an input electricity indicator. The pulse generation circuit generates electric pulses that resonance with the spinning of the flywheel rotor assembly200. The input electricity indicator indicates whether there is pulse current passing through the input driver coils330. The pulse driver circuit is connected to the input power source.

In the embodiment shown inFIG. 4, the pulse generation circuit includes the input power source402, the optical sensor switch360, an n-channel MOSFET410, and a resistor420. In some embodiments, the input power source402is a 12V DC battery that provides power for the pulse generation circuit. The n-channel MOSFET410switches the potential across the input driver coils330. The input power source402is electrically connected to the input driver coils330of the input driver coil assemblies320of the input driver plate assembly300. The output from the optical sensor switch360is being channeled to the gate of the MOSFET410to initiate the pulse signal feed to the input driver coils330. The negative side of input power source402is connected to the source of the n-channel MOSFET410.

The resistor420is connected across the gate and the source of the n-channel MOSFET410and provides protection of the pulse generation circuit of the possible sudden current changes. The resistivity of the resistor420can be about 10 k ohm or larger, for example, about 100 k ohm. One wired end of each input driver coil330is connected to the positive terminal of the input power source402and the other wired end of the input driver coil330is connected to the drain of the MOSFET410.

In some embodiments, the input electricity indicator includes an LED440and a resistor450. The anode of the LED440is connected to the positive terminal of the input power source402and the cathode of the LED440is connected to the drain of the n-channel MOSFET410with an in-series 1 k-ohm resistor450. The LED is turned on when a potential is applied to the input driver coils330. In an alternative embodiment, a portion of the output power generated by the electricity output assembly500may be used to provide input power, instead of using the input power source402(e.g., a 12-volt battery).

FIG. 5is a planar side view of the electricity output assembly500. In one embodiment, the electricity output assembly500is positioned adjacent to the outer circumference of the flywheel rotor assembly200. The electricity output assembly500may include the coil support520and one or more output coils510. The output coils510may be composed of 24 AWG magnetic wires with about 1300 windings. The coil support520accommodates the output coils510. The surface of the output coils510closest to the flywheel rotor assembly200is positioned about 0.25 inches away from the outer circumference of the flywheel rotor assembly200. In some embodiments, the sizes of the output coils510is approximately 2.5 inch×2 inches×0.875 inch.

As the flywheel rotor assembly200rotates around the shaft270, the cutting of the magnetic flux from the external permanent magnets230on the output coils510generates an electrical current in the wire of the output coils510. In one embodiment, several output coils510might be used around the circumference of the flywheel rotor assembly200in order to increase the power generation. In the example as shown inFIG. 5, three output coils510are used resulting in a total output of the electricity output assembly500to be 35 volts AC when the flywheel rotor assembly200is running about 250 RPM rotating speed. In an alternative example, a portion of the output power being generated by the flywheel rotor assembly200may be used to power the pulse driver circuit400.

FIG. 6is a three-dimensional schematic view of a dual-rotor type of another example of an electromagnetic power generator device700in accordance with one or more embodiments of the invention. The electromagnetic power generator device700includes two flywheel rotor assemblies750rotating in opposite direction (e.g., arrow A around the shaft270and arrow B around the shaft270) to eliminate procession problem. Each flywheel rotor assembly750has its own input driver plate assembly300positioned within their central recess regions of the circular nonferrous inner frame220.

The two flywheel rotor assemblies750may be rotated in counter directions in order to reduce and essentially eliminated gyroscopic effect often observed on a single rotating rotor assembly. The shaft270passes through the central holes of the two flywheel rotor assemblies750and is supported by a support frame680. The support frame680may be vertical arms or some other support mechanism, such as a housing enclosure. In an alternative embodiment, a portion of the total out power being generated by the dual-rotor electric generator device700may be used to power the pulse driver circuits400.

FIG. 7is a flow diagram illustrating a method700of using one or more electromagnetic power generator devices to generate electricity in accordance with one or more embodiments. The method700include an optional step702of applying an initial start-up force to rotate a flywheel rotor assembly, and a Step710of triggering an optical sensor switch positioned on an input driver plate assembly. The initial startup force might be applied by hand, a magnetic flux pulse, or by some other mechanical means. The startup force starts the flywheel rotor assembly to rotate about a shaft pass through the center of the flywheel rotor assembly and the center of the input driver plate assembly. Rotating one or more flywheel rotor assemblies can trigger an optical sensor switch of a pulse driver circuit, which in turn closes a pulse generation circuit, resulting in a controlled magnetic flux pulse from one or more driver coil assemblies of the input driver assembly300.

At Step720, an electric current is generated through the input driver coils of an input driver coil assembly to generate a magnetic field. The driver input coils wrap around an iron core having a first end and a second end, and an input driver permanent magnet is attached to the first end of the iron core.

At Step730, a neutral magnetic flux gap distance “D” is maintained between the second end of the iron core and an inner edge of the circular nonferrous inner frame of the one flywheel rotor assembly to balance the attraction force and the repulsion force. In one embodiment, the internal permanent magnets and the input driver permanent magnets are positioned to face and pass each other in the same magnetic polarity.

In addition, a magnetic flux amplification is generated by providing an attraction force from the magnetic field generated from the input driver coil assembly to attract internal permanent magnets positioned inwardly apart on a circular nonferrous inner frame that is attached coaxially on an inner circumference of a circular ring of the flywheel rotor assembly. Further, a repulsion force is provided from the input driver permanent magnet to repulse the internal permanent magnets and counterbalance the attraction force of the magnetic field.

At Step740, a controlled magnetic flux pulse force from the one or more input driver coil assemblies of the input driver plate assembly is generated to rotate the flywheel rotor assembly at a high rotating speed without hindrance. The rotating flywheel rotor assembly driven by the controlled magnetic flux pulses eventually reaches an operating rotational velocity.

At Step750, an electric power is generated by generating an electric current from the magnetic field of external permanent magnets positioned outwardly apart on a circular nonferrous outer frame that is attached coaxially on an outer circumference of the circular ring of the flywheel rotor assembly. For example, an output current is generated in the one or more output coils positioned circumferentially adjacent to the rotating flywheel rotor assembly.

At Step760, optionally, one or more electricity output assemblies having on or more output coils are positioned near the flywheel rotor assembly within the flywheel type electromagnet system. At Step770, the electric power is collected by the one or more electricity output assembly having one or more output coils.

Embodiments of the invention provide a flywheel type electromagnet system and a method of using the flywheel type electromagnet system for generating large amount of electric power. In one embodiment, the flywheel type electromagnet system includes one flywheel per unit mounted in a perpendicular position on a non-rotating shaft. In another embodiment, the flywheel type electromagnet system includes two flywheels mounted side by side on a non-rotating shaft where the two flywheels may rotate and spin in the same or opposite direction. In a preferred embodiment, the two flywheels are spinning in an opposite rotating direction to each other to eliminate the precession problem during flywheel rotation.

Additional flywheels can be added to the flywheel type electromagnet system to include three, four or any other additional number of flywheels installed on a single fix-positioned and non-rotating shaft to generate higher total electrical power output. For example, a flywheel type electromagnet system can be modified to include multiple units of two flywheel pair, each flywheel pair having two flywheels to rotate in opposite direction.

Accordingly, the invention provides the electromagnetic power generator device100and a method thereof for using balanced electromagnetic forces to drive one or more flywheel rotor assemblies200on a fixed shaft and generate large amount of electrical power. The electromagnetic power generator device includes a non-rotating shaft attached to a support frame, at least one flywheel rotor assembly, and at least one input driver plate assembly which is coupled to the flywheel rotor assembly via the non-rotating shaft penetrating through a first centered hole of a bearing of the flywheel assembly and a second centered hole of the input driver plate assembly.
