BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described by using a commercial power source, for example, for a building (company, office building,
An example will be described in which electricity is stored in a power storage device installed in a general house or apartment. Since the embodiment described in the embodiment of the present invention is an example, a power supply for driving a drive motor, which will be described later, and a power storage device for storing electricity extracted from a permanent magnet generator may be the same. The present invention can be applied not only to real estate but also to movable products such as automobiles and ships.

FIG. 1 is a process chart of the power storage method of the present invention. FIG. 2 is a block diagram of a power storage device used directly in the method invention. 3 to 8 are schematic cross-sectional explanatory views of a permanent magnet generator in the power storage device used directly in the method invention. Therefore, first, the power storage method will be described. For the sake of convenience, the names of the members and devices are denoted by the reference numerals used in the description of the invention of the product (the power storage device Y and an example of the permanent magnet generator X). Use as is.

A is a drive motor starting step. In this drive motor starting step A, as shown in FIG.
The drive motor 5 with the clutch mechanism 6 starts based on the control signal output from 0. As the drive motor 5, for example, a DC motor of model DME44SA manufactured by Nippon Servo is used. The drive motor 5 of this model DME44SA is
Rated output is 9.2V, rated voltage is 0.50 with no load
A, 3,600 r. p. m
It is. On the other hand, the power supply 5 for starting the drive motor 5
1 is an AC commercial power supply.

The control device 50 sets the first switch 52 for supplying power to the power supply 51 to the “ON” state, and sets the second switch 54 for the power storage device 53 as an example of a resistor to “OF”.
F ”, and the first converter (AC / DC converter) 55
, The drive motor 5 is started and the clutch mechanism 6 is simultaneously operated in the connecting direction.

Therefore, in the drive motor starting step A of the present embodiment, when the drive motor 5 is started, the fixed winding (generation coil) 24 of the permanent magnet type generator X is not loaded (resistance is applied to the generation coil). In this state, the drive motor 5 is rotated only by the input power. At this time, input power on the drive motor side = input energy> kinetic energy of the flywheel rotating body. That is, comparing the input energy with the kinetic energy of the flywheel rotating body, when the flywheel rotating body 10 of the permanent magnet type generator X starts to rotate from the stop state of the drive motor 5,
Since the input power (electromotive force) to the drive motor 5 is large and the rotation speed of the flywheel rotating body 10 is small (the peripheral speed of the flywheel rotating body 10 is small), the input energy> kinetic energy.

B is a high-speed rotation step of rotating the flywheel rotating body 10 at high speed. In this high-speed rotation process B, the control device 50 continues to drive the drive motor 5 and gradually rotates the flywheel rotor 10 having the permanent magnet rotor 12 of the permanent magnet generator X from low-speed rotation to a constant high-speed rotation. To high speed. In this case, the control device 50
Drives the drive motor 5 and simultaneously supplies electricity to the clutch mechanism 6. Upon receiving the power supply, the clutch mechanism 6 brings the output shaft 5a of the drive motor 5 and the rotating shaft 11 of the flywheel rotating body 10 into a connected state. Thereby, the flywheel rotating body 10 of the permanent magnet type generator X
Keep rotating by the driving force of the driving motor 5.

In the high-speed rotation step B, the peripheral speed (the number of revolutions) of the flywheel rotator 10 gradually increases due to its inertia, and the input power of the drive motor 5 and the kinetic energy of the flywheel rotator 10 eventually become equal. . That is, the aforementioned input energy = kinetic energy.
The flywheel rotor 10 has a larger inertia moment (acceleration) as its mass and radius are longer. Each of the permanent magnet generators X to X4, which will be described later,
At least one or more annular permanent magnetic portions 16 having permanent magnets 15 disposed annularly at appropriate positions in the radial direction about the rotation shaft 11 (concentric circles).

C is an axis-linked cutting and drive motor stopping step. In this shaft-linked cutting and drive motor stopping process C,
After the kinetic energy of the flywheel rotator 10 becomes larger than at least the input power energy of the drive motor 5, the interlocking relationship between the drive shaft 5a of the drive motor 5 and the rotation shaft 11 of the flywheel rotator 10 is cut off. At the same time, the drive motor 5 is stopped.

In this case, when the peripheral speed of the flywheel rotating body 10 increases (the number of rotations increases), its kinetic energy (formula: 1/2 MV ² , M = mass) depends on the relationship with the mass of the flywheel rotating body 10. , V = peripheral speed) becomes larger than the input energy of the drive motor 5. To add, doubling the mass doubles the kinetic energy. Also by increasing the diameter of the flywheel rotating body, at the same rotational speed, the peripheral speed increases by "V ^2". Therefore, since the mass and diameter of each permanent magnet rotor of each of the permanent magnet generators X to X4 used in the method or the apparatus of the present invention are rationally configured based on the natural law, the input Energy <kinetic energy.

In the shaft interlocking cutting and drive motor stopping step C, whether or not the kinetic energy of the flywheel rotating body 10 is at least larger than the input power energy of the drive motor 5 is determined by a permanent magnet type. The rotation speed is detected by the rotation speed detection means 29 provided in the support member 4 of the generator X. The detection signal of the rotation speed detecting means 29 is sent to the control device 50. The control device 50 sends, for example, “the flywheel rotator 10
When the detection signal of "the kinetic energy becomes larger than the input power energy of the drive motor 5" is received, the driving of the drive motor 5 is stopped by setting the power supply 51 first power supply switch 52 to the "OFF" state. At the same time, the power supply to the clutch mechanism 6 is stopped, and the clutch mechanism 6 is connected.
Operate in the direction of disengagement. At this time, the flywheel rotating body 10 in which the interlocking relation of the shaft is disconnected via the clutch mechanism 6 is rotating at a high speed due to its inertia force.

D is an electric storage process for extracting electricity from the permanent magnet type generator X. In this electric storage step D, the shaft-linked cutting and drive motor stopping step C is premised, and the gap 22 is formed annularly with respect to the annular permanent magnetic portion 16 of the permanent magnet rotor 12 of the flywheel rotating body 10. Electricity is taken out from the arranged stator winding (power generation coil) 24 and is stored in a power storage device 53 installed in a real estate or a movable property. When the current taken from permanent magnet type generator X is AC, while power storage device 53 is DC, power is stored via second converter (AC / DC) 56. Of course, depending on the combination, the first converter 55
The second converter 56 is unnecessary.

When the electricity is stored in the power storage device 53, for example, the control device 50 operates as described above.
When the power supply first switch 52 is set to the “OFF” state or the like to stop the power supply, the control device 50 sets the second switch 54 for the power storage device 53 to the “ON” state at that moment, and the stator The winding (power generation coil) 24 is switched from a no-load condition to a load condition. Thus, the stator winding 2
When a load is applied to 4, a so-called back electromotive force is generated. Therefore, the power storage device 53 stores electricity while the flywheel rotating body 10 continues to rotate with respect to the stator winding 24 by its inertia force.

Here, in order to deepen the understanding of the present invention, the kinetic energy of the flywheel rotating body 10 and the stator winding 2
The relationship with work energy of No. 4 will be described. Comparing the two energies, the condition that the kinetic energy of the flywheel rotating body 10 becomes “0” is when the inertia of the flywheel rotating body 10 is lost and the flywheel rotating body 10 stands still. At this time, the work energy of the stator winding 24 naturally becomes "0". Therefore, in other words, the flywheel rotating body 1
The kinetic energy of 0 is offset by the work energy of the stator winding 24 (the amount of work by power generation). Therefore, so to speak, the work by the power generation of the stator windings 24 causes the kinetic energy of the flywheel rotating body to be "0".

Therefore, it is now assumed that “FRAI · W = kinetic energy of flywheel rotating body 10, HATSUDEN
= Power generation energy (back electromotive force) of the stator winding 24 until the flywheel rotating body 10 stops, α = frictional energy of shaft bearing torque and energy of air resistance,
MOTER = input energy of drive motor "
FRAI · W = HATSUDEN + α. In the case of this formula, the aforementioned α is much smaller than the respective energies of “MOTER and FRAI · W”, and therefore, when considered as “0”, FRAI · W = HATSUDEN.

Next, as in the invention of the method of the present invention, while the drive motor 5 and the flywheel rotating body 10 are interlocked, the condition that the stator winding 24 is irrelevant (no load condition); Further, under the condition that the drive motor 5 is irrelevant (stops driving) while the flywheel rotating body 10 rotates by inertial force and the flywheel rotating body 10 and the stator winding 24 are in a power generation relationship, "MOTER", "FRAI
・ W ”and“ HATSUDEN ”are related by syllogism, and MOTER <FRAI · W, and F
RAI.W = HATSUDEN, and therefore MO
TER <HATSUDEN.

E is a step of stopping power storage and restarting the drive motor. In this power storage stop and drive motor restart process E,
When the flywheel rotating body 10 that is rotating due to inertial force drops to a certain number of rotations, the control device 50 performs a similar operation to the above-described drive motor starting step A based on the detection signal of the above-described rotation speed detecting means 20. The first switch 52 for supplying power to the power supply 51 is set to the “ON” state, and the second switch 54 for the power storage device 53 during storage is set to the “OFF” state. The control device 50 activates the drive motor 5 and simultaneously activates the clutch mechanism 6 in the connecting direction. Therefore, the flywheel rotating body 10 rotating by the inertial force is again accelerated to the high-speed state by the driving force of the driving motor 5. At this time, since no resistance is given to the stator winding 24 as described above, the state is a no-load state (non-power generation state).

Here, the steps D and E will be specifically described. The flywheel rotor 10 is driven by the back electromotive force of the stator winding 24, for example, at 3,600 rpm.
p. m to 3,000 r. p. When the value falls to m, the power generation (resistance) of the stator winding 24 is stopped, and the drive motor 5 is started again. At this time, the flywheel rotating body 10 has a rotation speed of 3,000 rpm. p. m, so that no large electromotive force is required for the drive motor 5,
In other words, power consumption of the drive motor 5 is sufficient. As described above, according to the present invention, the stator winding 24 is caused to repeatedly and intermittently start the drive motor 5 in a no-load state, and the flywheel rotor 10 is easily brought into the high-speed rotation state via the clutch mechanism 6. So that you can go.

Therefore, the present invention including the permanent magnet type generator X can repeat the steps A to E in order to send electricity to the electric storage device 50 or the resistor installed in the real estate or movable property.

The remaining structure is the same as that of the first embodiment. Therefore, the arm-shaped conductor mounting portion 23A
Is fixedly supported by a cylindrical support 4a having a lower end fixed to the base 1A. A storage box 7A containing a clutch mechanism 6A is integrally provided below the drive motor 5A, and the drive motor 5A is supported so that the output shaft 5a is coaxial with the rotation shaft 11A of the flywheel rotating body 10A. It is fixed to a support plate (upper lid) 4b of the member 4A. With this configuration, the weight of the permanent magnet rotor 12A can be reduced, and the size of the permanent magnet generator X1 itself can be reduced.

Next, the permanent magnet generator X2 of the third embodiment shown in FIG. 6 is different from that of the first embodiment mainly in that the flywheel rotating body 10B ( The rotation shaft 11B + the permanent magnet rotor 12B) is provided with at least one or more iron annular plates 26 fixedly provided on the permanent magnet rotor 12B. In this embodiment, a total of two iron annular plates 26 sandwich one annular permanent magnetic portion 16B and two projecting conductor mounting portions 23B of the permanent magnet rotor 12B with some gap. Of the arm portion 14B and the arm portion 14B
Are fixed crosswise to the outer ends.

By the way, in this embodiment, the inner steel annular plate 26 opposed to the pipe-shaped synthetic resin molded portion 13B side is used.
And the outer iron annular plate 26 facing the inner wall surface of the cylindrical support portion 4a of the support member 4B have substantially the same thickness, but in order to give the flywheel rotor 10B a mass, It is desirable to make the iron annular plate 26 thicker than the inner one.

Next, the rotation mark 20 of the rotation speed detecting means 20B is used.
a is provided on the peripheral wall surface of the lower end 11b of the rotating shaft 11B of the flywheel rotating body 10B, while a tachometer 20b capable of detecting the passage of the rotation mark 20a is provided on the inner wall surface of the base 1B. It is. With this configuration,
The moment of inertia of the flywheel rotating body 10B can be increased, and as a result, the amount of power generation of the permanent magnet generator X2 can be increased.

Next, the permanent magnet type generator X3 of the fourth embodiment shown in FIG. 7 is mainly different from that of the first embodiment in that the output shaft 5a of the drive motor 5C and the storage box 7 are provided.
The drive gear 2 is connected to a connection / disengagement shaft 29 of a drive gear 28 which is connected and rotated by a clutch mechanism 6C in the drive gear 2C.
This is the point that the rotating shaft 11C of the flywheel rotating body 10C having the driven gear 30 meshed with the rotating shaft 8 is non-coaxially located. That is, the permanent magnet type generator X3 is configured so that the rotation speed of the flywheel rotating body 10C can be increased by a so-called gear system.

The drive motor 5C is suspended from the center of the support member 4C via the support arm 31 having a gate-shaped cross section and fixed to the upper center of the horizontal support plate 4b.

With this configuration, the driving force of the driving motor 5C is transmitted to the driving gear 28 via the clutch mechanism 6C, and as a result, the flywheel rotor 10C is connected to the connecting / disengaging shaft 29 by the output shaft. When it is connected to 5a, it rotates at a high speed corresponding to the gear ratio of the driving gear 28 and the driven small gear 30 that always mesh with each other, so that the power generation amount of the permanent magnet generator X3 can be increased.

Next, the permanent magnet generator X4 of the fifth embodiment shown in FIG. 8 is different from that of the first embodiment mainly in that the output shaft 5a of the drive motor 5D and the storage box 7D The rotating shaft 11D of the flywheel rotating body 10D having the driven gear 30D meshed with the driving gear 28D is non-coaxial with the connecting / disengaging shaft 29D of the driving gear 28D which is connected and rotated by the clutch mechanism 6D. It is a point located above. That is, similarly to the permanent magnet generator X3 of the fourth embodiment, the permanent magnet generator X4 also employs a so-called gear system to form the flywheel rotator 1.
It is configured so that the number of rotations of 0D can be increased. The drive motor 5D is suspended from the central portion of the support member 4D via a support arm 31D having a gate-shaped cross section and fixed to an upper central portion of the horizontal support plate 4b.

The flywheel rotor 10D is of a magnetic levitation type in which the flywheel rotator floats by repulsive force of the magnetic members facing each other, and is an angle bearing fixed to the upper central portion of the horizontal support plate 4b of the support member 4D. That is, it rotates while being received by the plate 35.

The features of the magnetic levitation system will now be described. First, reference numeral 36 denotes a circular recess formed widely on the upper surface 1a of the base 1D, and a fixed yoke 37 made of iron having a cross section as a first magnetic body is fixedly fitted in the circular recess 36. The first magnetic body 37 has a magnet 38 at the center of the inner wall surface. In this embodiment, the upper surface of the magnet 38 is the south pole, while the lower surface is the north pole. Therefore, the magnet 38
The upper surface of the peripheral end of the iron fixed yoke 37 which is affected by the polarity (N pole) and has a function of forming magnetism is an N pole.

On the other hand, 40 is a flywheel rotating body 10D.
Is a floating yoke made of an inverted-concave section as a second magnetic body fixed to the lower end 11b of the rotary shaft 11D. This second
The magnetic body 40 has a flat floating magnet 41 fixed to the center of the inner wall surface. In this embodiment, the lower surface side of the floating magnet 41 is the south pole, while the upper surface side is the north pole. Therefore, it is affected by the polarity (N pole) of the levitation magnet 41, and
The lower surface at the peripheral end of the iron floating yoke 40 having the function of forming magnetism is an N pole. Therefore, the upper and lower ball bearings 8D,
The flywheel rotator 10D rotatably supported via the 8D is supported via the second magnetic body 40 on the rotating shaft 11D that repels and floats in accordance with the polarity of the first magnetic body 37 on the base 1D. It always floats and is received at a predetermined position via an angled bearing plate 35 provided on the support member 4D.

The upper end of the rotary shaft 11D penetrating the horizontal support plate 4b of the support member 4D is formed in a conical shape in order to avoid frictional resistance with the bearing plate 35 as much as possible. Also in this embodiment, the outer annular permanent magnetic portion 16D is made thick to increase the mass of the flywheel rotator 10D, to obtain a so-called sufficient flywheel effect, and to prevent vibration or blurring. Or a thicker or larger radius of the iron floating yoke 40 as the second magnetic body. Further, as in the third embodiment, a connecting arm is connected to the outer annular permanent magnetic portion 16D. The iron annular plate 26 may be integrally attached via the intermediary.

Each of the permanent magnet generators X to X4 having the above configuration
Rotates with the output shaft of the drive motor when the drive motor is activated and the clutch mechanism is directly or indirectly connected to the rotary shaft of the flywheel rotator. Therefore, the flywheel rotating body rotates at high speed in conjunction with the drive motor, and this rotating speed can always be detected by the rotating speed detecting means. In addition, since the magnetic field of the permanent magnet rotor of the flywheel rotating body crosses the stator winding of the stator in a cross direction, an induced voltage is generated, and in the case of a load, the induced voltage is generated from the stator winding. It is possible to extract electricity.

On the other hand, when the connection between the clutch mechanism and the rotating shaft of the flywheel rotating body is disconnected, the flywheel rotating body continues to rotate due to inertial force. Therefore, the rotating force of the flywheel rotating body that has been disconnected from the drive motor gradually decreases thereafter, but the drive motor restarts and the connection between the clutch mechanism and the flywheel rotating body is re-established. When this is achieved, the flywheel rotating body that is rotating at low speed rotates again to high speed. In this case, it is desirable that the drive motor is stopped and the stator winding is in a no-load state (a state in which no electricity is taken out).

Next, the storage means 58 in the power storage device of the present invention stores the driving of the drive motor 5, the operation of the clutch mechanism 6, and the resistance state of the stator winding 24 intermittently by those skilled in the art. An intermittent control program to be controlled can be stored. Therefore, when a timer-like program is stored in the storage means 58, it is not always necessary to provide the rotation speed detecting means 20 for detecting the rotation speed of the flywheel rotating body 10 in each permanent magnet type generator. The control device in the power storage device includes an AC / DC converter and a DC
