Description

  The present invention relates to a generator, a motor, and a power supply system using the same. The use as a motor is not limited and is applied to various fields. The application of the power supply system is not limited and can be applied to various fields. For example, there are a power supply device at home and a power supply device at a factory or building. Further, for example, there are power supply mechanisms for vehicles such as electric vehicles, hybrid vehicles, electric motorcycles, special vehicles, and the like, which can be applied to various fields.

A generator is a device that converts kinetic energy into electrical energy, and a motor is a device that converts electrical energy into kinetic energy, and there are various types. In general, a motor can rotate continuously by supplying power to the armature to generate a magnetic field, rotating it by obtaining the magnetic attractive force and magnetic repulsive force obtained from the field, and switching the polarity of the armature It is a mechanism. On the other hand, when mechanical rotational drive energy is applied to the motor shaft, it is possible to extract electrical energy, which can be diverted as a generator.
A hybrid electric vehicle uses an efficient combination of kinetic energy obtained by an internal combustion engine of gasoline and electric energy stored and consumed by a motor generator. Thus, as hybrid electric vehicles become widespread, in recent years, motor generators that efficiently process both conversion from kinetic energy to electric energy and conversion from electric energy to kinetic energy have attracted attention.
The configuration of a conventional hybrid electric vehicle includes an internal combustion engine and an electric motor, and is configured to transmit the power of the internal combustion engine and the electric motor to the wheels while interlocking both via a power switching / transmission mechanism. When the motor generator operates as a motor, it is driven and controlled as an electric motor that converts electric energy into kinetic energy via a power converter. On the other hand, when operating the motor generator as a power generator, the motor generator is operated as a power generator that converts the rotational power of the internal combustion engine into electric energy via the power converter, and the storage battery is charged via the power converter.
In addition, not only hybrid electric vehicles but also private power generation is attracting attention for the prevention of global warming. Under such circumstances, a power supply system that can supply electrical equipment with the necessary amount of electricity generated when necessary, or the kinetic energy that is normally unconsciously consumed is converted into electrical energy for storage. A power supply system that supplies electric power when electrical energy is required has attracted attention.
Large generators such as turbines for thermal power generation and generators for hydroelectric dams are unsuitable for private power generation as described above. Therefore, a small permanent magnet generator composed of a plurality of permanent magnets and a plurality of coils is often used (see, for example, Patent Document 1).
The configuration of a conventional small permanent magnet generator has a structure in which a plurality of coreless coils are arranged, and permanent magnets are arranged around the coreless coils so that magnetic flux penetrates them. For example, the structure is as shown in FIG. A conventional small permanent magnet generator 1 includes a fixed shaft 2, a rotating case 3, a base 4, a plurality of coreless coils 5, a plurality of first permanent magnets 6, and a plurality of second permanent magnets 7. A structure consisting of is shown. The number of the first permanent magnets 6 and the number of the second permanent magnets 7 are the same, and are arranged at positions facing each other. The opposing surfaces of the first permanent magnet 6 and the second permanent magnet 7 have opposite polarities. As a result, lines of magnetic force are formed from the first permanent magnet 6 to the second permanent magnet 7 or from the second permanent magnet 7 to the first permanent magnet 6. This magnetic field line can penetrate the air core 12 of the coreless coil 5.
FIG. 11B is a diagram in which the configuration of FIG. As shown in FIG. 11B, the coreless coil 5 crosses while rotating between the first permanent magnet 6 (N pole) and the second permanent magnet 7 (S pole) so as to face each other vertically. Yes. In other words, a large number of coreless coils 5 are arranged on the rotor, and the first permanent magnet 6 to the second permanent magnet 7 are arranged so as to face each other vertically.
When the rotor 10 shown in FIG. 11 (a) rotates with the rotation of the rotating shaft, the coreless coil 5 passes so as to cut off the magnetic flux generated between the first permanent magnet 6 and the second permanent magnet 7 facing each other. Go. If rotational kinetic energy is given to the electromagnetic generator configured in this way, as shown in FIG. 11B, most of the magnetic flux 11 generated from the N pole of one permanent magnet 10 is the coreless coil 5. , And flows toward the south pole of the other permanent magnet 10, so that if the coreless coil 5 moves, an electromotive force is generated and power can be generated.
In the above relationship, the side on which the permanent magnet is fixed and the side on which the coreless coil 5 rotates are described. However, the opposite is true, the side on which the first permanent magnet 6 and the second permanent magnet 7 rotate, and the coreless side. The side on which the coil 5 is fixed can operate in the same manner to generate power.

Not only small permanent magnet generators, motor generators are always challenged to improve power generation efficiency. Ideally, the rotational kinetic energy can be converted to electrical energy with 100% efficiency.
In order to increase the amount of power generation using the conventional small permanent magnet generator, the magnetic flux generated from the first permanent magnet 6 and the second permanent magnet 7 is surely penetrated through the core portion of the coreless coil 5 without leaking to the other. There is a method in which the distance between the upper and lower first permanent magnets 6 and the second permanent magnet 7 facing each other with the coreless coil 5 sandwiched therebetween is reduced.
However, when the conventional small permanent magnet generator is used, it is necessary that nothing is sandwiched between the first permanent magnet 6 and the second permanent magnet 7 facing each other. In addition, it is difficult to keep the second permanent magnets 7 in a state where they are close to each other without being sandwiched between them, and the first permanent magnet 6 and the second permanent magnet 7 facing each other must be separated to some extent. Further, when the number of turns of the coreless coil is increased in order to increase the amount of power generation using the conventional small permanent magnet generator, the thickness of the coreless coil 5 is increased, so that the first permanent magnets disposed above and below the coreless coil 5 are increased. 6 and the 2nd permanent magnet 7 must spread.
Therefore, in order to ensure that the magnetic flux generated from the first permanent magnet 6 and the second permanent magnet 7 does not leak to the other and penetrates the core portion of the coreless coil 5, the distance between the upper and lower first permanent magnets 6 and the second permanent magnet 7. There is a limit to the method of approaching.
Also, when increasing the number of permanent magnets to increase the amount of magnetic flux in order to increase the amount of power generation using the conventional small permanent magnet generator, the weight increases as the number of permanent magnets increases. As a result, there arises a problem that the weight of the entire small permanent magnet generator increases.
The conventional small permanent magnet generator has a structure in which a rotor provided with a coreless coil 5 rotates in order to cross the flow of magnetic flux. The coreless coil 5 has an electric drawer for extracting electric energy. It is desirable that the coreless coil 5 does not rotate because the wires are wired.
However, in the configuration of the conventional small permanent magnet generator, since the coreless coil 5 is configured to rotate with the rotor 10, a member such as a conductive brush must be provided, and the configuration of the lead wire or the like is required. It becomes complicated.
On the other hand, when the coreless coil 5 side is fixed and the first permanent magnet 6 and the second permanent magnet 7 side are rotated, the weight of the magnet is large as described above. The problem of adversely affecting the product will occur.
In view of the above problems, the present invention captures more magnetic flux generated around the permanent magnet by the coreless core while reducing the size and weight by reducing the amount of the permanent magnet used, and high power generation efficiency can be obtained. An object is to provide a generator and a self-generating motor.

In order to achieve the above object, the generator of the present invention includes a rotating shaft, a rotor configured to be rotatable in conjunction with the rotating shaft, and the same poles facing each other between adjacent permanent magnets. A plurality of permanent magnets arranged in a circular pattern on the rotor and a plurality of coreless coils are arranged in a circular pattern, and the first coil is provided on one end surface of the rotor so as to face the permanent magnets. An assembly, a plurality of coreless coils are arranged in a circular shape, a second coil assembly provided to face the permanent magnet on the other end surface of the rotor, and a plurality of coreless coils are arranged in a circular shape. And a third coil assembly provided to face the side surface of the rotor.
With the above configuration, when the permanent magnet rotates, the magnetic flux emitted from one magnetic pole to the surroundings is generated by three of the first coil assembly, the second coil assembly, and the third coil assembly. Captured efficiently. That is, the coil exists in any direction on the upper surface side, the lower surface side, and the side surface side, and the magnetic flux can be efficiently captured. In the above configuration, the arrangement of the magnetic poles of the permanent magnets is the same, so that the magnetic flux of the permanent magnets can be easily emitted toward the outside of the rotor. On the other hand, if the arrangement of the magnetic poles of the permanent magnet is different from each other, the magnetic flux of the permanent magnet is confined inside the rotor.
Here, the generators can be stacked in series to increase the power generation efficiency. That is, a plurality of the generators are stacked in series with the rotation shaft in common, and each of the generators is connected to the rotation shaft via a clutch, and the rotation shaft is connected through connection / release of the clutch. It can be set as the structure provided with the clutch control part which performs the number control of the said common generator.
When the generators are stacked in series, the magnetic poles of the permanent magnets of adjacent rotors have the same polarity, so that the magnetic flux of the permanent magnets can be easily emitted toward the outside of the rotor. . In addition, since the magnetic fluxes repel each other if they are too close to each other, an appropriate interval is required. This is because if the arrangement of the magnetic poles of the permanent magnets is different from each other, the magnetic flux of the permanent magnets is confined in a distorted narrow magnetic flux loop.
Next, in order to achieve the above object, the self-generating motor according to the present invention further includes a motor in addition to the generator according to the present invention, and the rotating shaft of the generator is shared with the rotating shaft of the motor. A self-generating motor that converts part of rotational energy generated by the motor into electrical energy by the generator.
That is, while driving as a motor, the kinetic energy of surplus torque is converted into electric energy, and the high-efficiency generator of the present invention is used.
Here, in the configuration of the self-generating motor, the power generation efficiency can be increased by stacking the generators in series. That is, a plurality of the generators are stacked in series with the rotating shaft in common, and each of the generators is connected to the rotating shaft via a clutch, and is supplied to the rotating shaft by the motor. A clutch control unit for dynamically controlling connection / release of the generator to the rotating shaft by the clutch according to the magnitude of rotational torque and controlling the number of the generators according to the motor surplus torque; Can be configured.
By laminating in series, the rotational kinetic energy obtained from the rotating shaft can be converted into electrical energy as much as possible. The number of units can be limited by a clutch so that the load on the generator does not become larger than the rotational kinetic energy of surplus torque.
When the generators of the self-generating motor are stacked in series, it is preferable that the arrangement of the magnetic poles of the permanent magnet is the same between the rotors adjacent to each other in the stacking direction.
Since the arrangement of the magnetic poles of the permanent magnets of the adjacent rotors is the same, the magnetic flux of the permanent magnets is easily emitted widely toward the outside of the rotor. In addition, since the magnetic fluxes repel each other if they are too close to each other, an appropriate interval is required. This is because if the arrangement of the magnetic poles of the permanent magnets is different from each other, the magnetic flux of the permanent magnets is confined in a distorted narrow magnetic flux loop.
There are various uses for the self-generating motor of the present invention. For example, the self-generating motor of the present invention can be incorporated into various vehicles such as automobile tires such as passenger cars, trucks, and buses, motorcycles such as motorcycles, and aircraft and special vehicles.
Next, the power supply system of the present invention includes a power input source, a power consuming unit, and a power control unit that controls power input and consumption, and the power input source includes the self-generating motor of the present invention. , A solar panel and a household power source, and the power consuming unit is an electric device used by the power consumer and a self-generating motor of the present invention, and the power control unit is the Electric power for controlling the motor drive of the self-generating motor so that the amount of power supplied from the household power supply is minimized while the electric power required by the electric power consumption unit is supplied from the electric power input source. Supply system.
With the above configuration, while diversifying the power supply source, the power supply from the household power source is reduced to a small extent. In addition, since driving of the self-generating motor has two aspects of power consumption and power generation, it is only necessary to determine the driving amount by applying power feedback by the power control system.

  Hereinafter, the best mode for carrying out the present invention will be specifically described by way of examples. The present invention is not limited to these examples.

Example 1 is a configuration example of the first generator 100 of the present invention. The first generator 100 efficiently obtains an induced current by arranging a coil assembly in three directions around a permanent magnet.
FIG. 1 is a diagram schematically illustrating the basic configuration of the generator according to the first embodiment. The chassis is removed, and the internal structure is shown in exploded form so that the internal structure can be easily understood. Of the components of the generator, only the portions necessary for the explanation are drawn, and the illustration of other wirings and structures is omitted. FIG. 2 is a diagram illustrating a front view and a side view of the internal structure of the generator according to the first embodiment.
As shown in FIG. 1, the generator 100 of the present invention includes a rotating shaft 101, a rotor 110, a permanent magnet 111, a first coil assembly 120, a second coil assembly 130, and a third coil assembly 140. It has a structure with.
The rotary shaft 101 is supported by a bearing (not shown) so as to be rotatable by receiving a rotational force from the outside. The direction of rotation may be clockwise (clockwise) or counterclockwise (counterclockwise).
The rotor 110 is connected to the rotary shaft 101 via a rotary joint (not shown) so as to be rotatable in conjunction with the rotary shaft 101. The rotary joint is a member for fitting the rotary shaft 101 and connecting the rotary shaft 101 and the rotor 110. It is also possible to integrally form the rotating shaft 101 and the rotor 110 without providing a rotary joint.
As will be described later, the first coil body 120, the second coil body 130, and the third coil body 140 including the coreless coil for generating power are arranged on the outer periphery of the rotor 110. In consideration, in order to allow more magnetic flux from the permanent magnet 111 to pass through the coreless coil, it is desirable that the rotary shaft 110 and the rotary joint be non-magnetic.
The rotor 110 is disk-shaped and interlocks with the rotation axis. The rotor 110 is provided with a recess in which the permanent magnet 111 is accommodated, and the permanent magnet 111 is accommodated in the recess. That is, the permanent magnet 111 rotates as the rotor 110 rotates.
The permanent magnet 111 is prevented from falling from the recess. For example, it may be bonded to the wall surface of the recess, or the permanent magnet 111 may be sealed in the rotor 110 with resin.
The material of the rotor 110 may be a plastic material in consideration of ease of molding and processing, weight, and the like.
The permanent magnets 111 are bar magnets each having an arc shape, and are polarized in the longitudinal direction. The permanent magnet 111 is a member for exciting magnetic flux that passes through the air core portion of the coreless coil included in the first coil body 120, the second coil body 130, and the third coil body 140. Although the raw material of a magnet is not limited, For example, the neodymium magnet etc. which are rare earth magnets which have neodymium, iron, and boron as a main component are mentioned.
In the rotor 110, the permanent magnets 111 are arranged in a circular shape so that the adjacent permanent magnets 111 face each other with the same polarity.
Here, the operation and effect when the adjacent permanent magnets 111 are arranged so that the same poles face each other will be described with reference to FIG.
FIG. 3A is a diagram showing a magnetic field excited by one permanent magnet 111. The magnetic flux emitted from the N pole in one permanent magnet 111 and returning to the S pole passes through a relatively narrow range on the side of the permanent magnet 111.
Next, FIG. 3B is a diagram illustrating a magnetic field excited by the permanent magnet 111 when the adjacent permanent magnets 111 are arranged so that different polarities face each other. When the different poles face each other, most of the lines of magnetic force enter from the north pole of one permanent magnet 111 to the south pole of the adjacent permanent magnet 111, and the magnetic flux is not launched around the rotor 110.
Next, FIG.3 (c) is the figure which showed the magnetic field which the permanent magnet 111 excites when it arrange | positions so that the same pole may oppose in the adjacent permanent magnet 111. FIG. By causing the same poles of the adjacent permanent magnets 111 to face each other, the magnetic lines of force generated from the respective N poles act so as to push each other, and the magnetic flux spreads and is emitted as shown in FIG. In this way, magnetic poles that spread so as to be pressed against each other are formed from the magnetic poles having the same poles opposed to each other, so that the magnetic field propagation area becomes wider than the magnetic flux shown in FIG. The magnetic flux density can be maintained at a high level even at a position some distance from.
If the distance between the adjacent permanent magnets 111 is too wide, the magnetic flux that is pushed as shown in FIG. 3C does not occur. Therefore, the distance between the permanent magnets may be adjusted at the design stage.
Next, the coil assembly will be described.
The first coil assembly 120 is formed by arranging a plurality of coreless coils in a circular shape so as to face the permanent magnet 111 on one end surface (upper surface in FIG. 1) of the rotor 110.
The second coil assembly 130 is formed by arranging a plurality of coreless coils in a circular shape and facing the permanent magnet 111 on the other end surface (the lower surface in FIG. 1) of the rotor 110.
The third coil assembly 140 includes a plurality of coreless coils arranged in a circular shape and is provided so as to face the side surface of the rotor 110.
Here, in the examples of FIGS. 1 and 2, the coreless coil used is a substantially fan-shaped first coil assembly 120 and a second coil assembly 130, and a substantially square shape of the third coil assembly 140, respectively. It is wound.
The coreless coil is installed in a fixed state. For example, if a structure such as a stator used as a general motor component is applied, it can be easily installed.
As these coreless coils, for example, an insulating film copper wire is wound around an air core. These coreless coils may be connected in series according to the phase of the output voltage, may be connected in parallel, or may be independent circuits. Thus, it is possible to cope with various kinds of power generation applications depending on how the coreless coils are connected.
In the first coil assembly 120 and the second coil assembly 130, the winding axis of the coreless coil is substantially parallel to the rotation shaft 101 so as to face the upper surface or the lower surface of the rotor 110. And it arrange | positions so that the rotation locus | trajectory of the permanent magnet 111 of the rotor 110 may be opposed.
In the third coil assembly 140, the winding axis of the coreless coil is substantially perpendicular to the rotating shaft 101 and is disposed so as to face the side surface of the rotor 110.
These elements are combined in the shape shown in the front view and the side view as shown in FIG.
Next, an outline of the operation when rotational energy is applied to the rotating shaft 101 of the generator 100 of the present invention will be described.
FIG. 4 is a diagram for briefly explaining the principle of operation when rotational energy is applied to the rotating shaft 101 of the generator 100 of the present invention.
In FIG. 4, one location near the outer peripheral edge of the rotor 110 is taken out and shown. Only a part of one permanent magnet (N pole) and only one coreless coil of each of the first coil assembly 120, the second coil assembly 130, and the third coil assembly 140 are shown. The other components such as the rotor 110 and the rotating shaft 101 are not shown.
When rotational kinetic energy is given to the rotating shaft, the rotor 110 rotates, and the permanent magnet embedded in the rotor also rotates. Magnetic flux is emitted from the magnetic pole of the permanent magnet.
4A, in the three directions around the permanent magnet 111, the first coil assembly 120 is upward, the second coil assembly 130 is downward, and the third coil assembly 140 is lateral. Are arranged facing each other, and each faces the permanent magnet 111.
As shown in FIG. 4B, when the rotor 110 rotates, the magnetic flux generated from the N poles of the plurality of permanent magnets 111 is the coreless coil of the first coil assembly 120 in the upper part and the second in the lower part. The coil assembly 130 passes through the coreless coil on the side, and passes through the core of the coreless coil of the third coil assembly 140 on the side. When the rotor 110 rotates and the permanent magnet 111 rotates, each coreless coil moves so as to cut the magnetic flux, and an induced current is generated. When the rotor 110 rotates and the next magnetic pole of the permanent magnet 111 comes, an induced current is generated in the same operation. As long as the rotor 110 continues to rotate in this way, an induced current continues to be generated.
This is the basic power generation principle of the generator 100 according to the present invention.
As described above, according to the generator 100 of the first embodiment, the structure is simple, and an induced electromotive force can be obtained from three directions during one rotation with a small number of magnets, and an excellent power generation effect can be obtained.
As mentioned above, although the structural example of the generator concerning Example 1 of this invention was shown, the said structure is an example and a various change is possible.

The second embodiment is a configuration example in which the generator 100 shown in the first embodiment is provided in a plurality of stages in series.
FIG. 5 schematically shows the configuration of the generator 100a according to the second embodiment in an easy-to-understand manner.
As shown in FIG. 5, the constituent elements of the generator 100 shown in the first embodiment are arranged in series, and the respective rotating shafts 101 are made common and unified. Note that the configuration example of FIG. 5 has a three-stage series configuration.
Thus, since the rotating shaft 101 is made common and unified, each rotor 110 is rotated by the rotational force applied to the rotating shaft 101 from the outside, and the generator 100 of each stage rotates. Kinetic energy is converted into electrical energy.
Here, a device for arranging the magnetic poles of the permanent magnets embedded in the rotor 110 in the series connection of the generators 100 at each stage will be described.
As described in the first embodiment, the permanent magnets 111 embedded in each stage of the rotor 110 are arranged in a circular pattern so that adjacent permanent magnets 111 face each other with the same polarity.
Here, when the generators 100 are stacked in series, the magnetic poles of the permanent magnets 111 are disposed so as to have the same polarity between the rotors 110 adjacent in the stacking direction. The effect will be described with reference to FIG.
FIG. 6A is a diagram illustrating a magnetic field excited by one permanent magnet 111. The magnetic flux emitted from the N pole in one permanent magnet 111 and returning to the S pole passes through a relatively narrow range on the side of the permanent magnet 111.
Next, FIG. 6B is a diagram illustrating a magnetic field excited by the permanent magnet 111 when the permanent magnets 111 adjacent to each other in the stacking direction are arranged so that the opposite poles face each other. When the different poles face each other in the stacking direction, the magnetic flux emitted from the N pole of the permanent magnet 111 enters the S pole of the permanent magnet 111 adjacent in the stacking direction. Will not be fired in the vicinity.
Next, FIG.6 (c) is the figure which showed the magnetic field which the permanent magnet 111 excites, when it arrange | positions so that the same polarity of the permanent magnet 111 adjacent to the lamination direction may oppose. By causing the same poles of the permanent magnets 111 adjacent to each other in the stacking direction to face each other, the magnetic field lines generated from the respective N poles act so as to push each other, and as shown in FIG. Is done. In this way, magnetic fluxes that spread so as to be pressed against each other are formed from the magnetic poles with the same poles facing each other, so that the magnetic field propagation area becomes wider than the magnetic flux shown in FIG. The magnetic flux density can be maintained at a high level even at a position some distance from.
If the interval between the permanent magnets 111 adjacent to each other in the stacking direction is too wide, the pressed magnetic flux as shown in FIG. 6C does not occur. Therefore, at the design stage, the interval in the stacking direction of the rotor 110 is set. Adjust it.
Since the principle of power generation in each stage of the generator 100 is the same as that of the first embodiment, description thereof is omitted here.
As mentioned above, although the structural example of the generator concerning Example 2 of this invention was shown, the said structure is an example and a various change is possible.

Example 3 is a configuration example of the self-generating motor 200 of the present invention.
FIG. 7A is a diagram schematically illustrating a basic configuration of a self-generating motor 200 according to the second embodiment. FIG. 7A schematically illustrates the internal structure so that it can be easily understood. Of the components of the self-generating motor 200, only the portions necessary for explanation are drawn, and the illustration of other wirings and structures is omitted.
As shown in FIG. 7 (a), the self-generating motor 200 of the present invention includes the generator 100 and the motor 210 of the present invention described in the first embodiment, and the respective rotations thereof. The shaft is provided in common and is housed in one housing.
The generator 100 of the first embodiment is a device that converts rotational kinetic energy given to the rotating shaft 101 from the outside into electric energy, but the self-generating motor 200 is generated on the rotating shaft 101 by the motor 210. This is a self-generating motor that converts a part of the rotational kinetic energy into electrical energy by using the generator 100 as a surplus.
That is, while driving as the motor 210, the excessive rotational kinetic energy is re-converted into electric energy and accumulated, and the high-efficiency generator 100 of the present invention shown in Embodiment 1 is used for power generation. Is.
Here, as shown in the second embodiment, a configuration in which the generators 100 are connected in multiple stages in series is possible. However, if the generator 100 is simply connected in multiple stages in series, the load applied by the generator 100 to the rotating shaft 101 increases, and if the excess rotational kinetic energy generated by the motor 210 is small, the rotating shaft There is a possibility that the load applied by the generator 100 becomes larger than the load 101 and the motor stops.
Therefore, as shown in FIG. 7B, it is desirable to provide a clutch mechanism 220 for each stage of the generator. FIG. 7B is a diagram showing a configuration example of a self-generating motor 200a provided with a plurality of stages of generators 100a on which the clutch mechanism 220 is mounted. In FIG. 7B, the mechanical structure of the clutch mechanism 220 is not shown.
As shown in FIG. 7B, the self-generating motor 200 a preferably includes a clutch control unit 230 that dynamically performs connection / release control of the clutch mechanism 220. That is, the clutch control unit 230 dynamically performs connection / release control of the generator 100a to the rotating shaft 101 by the clutch mechanism 220 according to the amount of excessive rotating torque applied to the rotating shaft 101 by the motor 210, The number of generators 100a is controlled according to the motor surplus torque.
In the case where the clutch mechanism 220 and the clutch control unit 230 are provided for the generator 100 at each stage, the rotation shaft is combined with the excess of the kinetic energy of the rotational torque generated by the motor 210 under the control of the clutch control unit 230. The number control for adjusting the number of generators 100 linked to the power can be performed, and the amount of electric power converted into electric energy and taken out can be made variable. That is, when the clutch control unit 230 detects that the kinetic energy surplus generated by the motor 210 is large, the number of the generators 100 that are connected to the rotating shaft 101 by operating the clutch 220 of each stage. And when the clutch control unit 230 detects that the excess rotational kinetic energy generated by the motor 210 is small, the number of the generators 100 connected to the rotary shaft 101 by operating the clutch 220 of each stage is determined. The operation of reducing is possible.
As described above, by laminating the generator 100 in series, the rotational kinetic energy obtained by the rotating shaft 101 can be converted into electrical energy as much as possible without waste. It is possible to incorporate a device for limiting the number of units in the clutch 220 so that the load on the generator does not become larger than the excessive rotational kinetic energy.
The configuration example of the self-generating motor according to the third embodiment of the present invention has been described above, but the above configuration is an example and various modifications can be made.

As a fourth embodiment, a power supply system 300 of the present invention will be described.
FIG. 8 is a diagram schematically showing a configuration example of the power supply system 300 of the present invention. As shown in FIG. 8, the power supply system 300 of the present invention is roughly configured to include a power input source, a power consuming unit, and a power control unit 340 that controls power input and consumption.
As the power input source, there are three types in the configuration example of FIG. 8, and the self-power generation motor 200 of the present invention described in the third embodiment and a self-power generation device 310 such as a solar panel or wind power generation. And a commercial power supply 320.
The self-generating motor may have a one-stage configuration or a three-stage series configuration with a clutch. Here, a self-generating motor 200a with a clutch in a three-stage series configuration is used. A device with a clutch is preferable because the amount of power generation can be finely controlled.
The commercial power source 320 is a power source provided by a power company or the like, and may be, for example, a general household AC power source.
The private power generation apparatus 310 is not particularly limited, and there are a solar panel and a wind power generation system that are widely used.
As described above, the power input source of the present invention uses the commercial power source 320 as the main power source, the auxiliary power source as the self-power generation motor 200a, and a self-power source 310 such as a solar panel that can be used as a general technology. It has been installed.
The battery 330 stores the electric power supplied by the self-power generation device 310 such as a solar panel and the self-power generation motor 200a. By using the battery 330, it is possible to temporarily store the power supply amount obtained in the private power generation device 310 and the self power generation motor 200a when the power supply amount is larger than the power consumed by the power consumption unit. Although the amount of power consumption is reduced when the householder is out of the home, etc., the amount of power obtained by the private power generation device 310 such as a solar panel or wind power generation may be large even when the householder is away. is there. In addition, since the amount of power generated in the private power generation apparatus 310 may change finely, power can be stably supplied to the power consumption unit via the battery 330.
As the power consumption unit, the configuration example of FIG. 8 shows two types of equipment 400 used by the power consumer and the self-generating motor 200a of the present invention. Electric power consumers are not particularly limited, and there are various types such as general households, apartment houses, commercial offices, stores, office buildings, and small factories. However, it is necessary to adjust the scale of the power supply system 300 of the present invention according to the scale of the power consumer. In addition, the self-generating motor 200a of the present invention also has a property as a power consuming portion because the motor 210 is a portion that consumes power.
The power control unit 340 is a part that controls supply and consumption of power. The power control unit 340 stores the power required by the power consumption unit from the power input source and is stored in the battery 330 and the power supply amount obtained from the private power generation device 310 and the self power generation motor 200. While dynamically considering the amount of power, power is supplied from the commercial power source 320 for the shortage, and the motor drive of the self-generating motor 200 is controlled so that the amount of power supplied from the commercial power source 320 is minimized. .
Since driving of self-generating motor 200a has two aspects of power consumption and power generation, power control system 300 may determine the driving amount by applying power feedback to self-generating motor 200a. In other words, if the drive of the self-generating motor 200a is increased, the amount of power generated by the generator increases, but the power consumption of the motor also increases. It may be difficult to determine how advantageous the power generation amount of the mold motor 200a is. Therefore, the power generation amount of the self-generating motor 200a can be adjusted by applying power feedback to the self-generating motor 200a.
As described above, the power supply system 300 according to the present invention reduces the power supply from the commercial power source 320 while diversifying the power supply sources.
