Definitions
- the present invention relates to a generator and a motor, and more particularly to a generator and a motor that generate power by minimizing external energy input and thereby drive the motor.
- the principle of Fleming's three fingers on the right hand is the principle.
- the principle is to cut the magnetic flux with a conductor, and it is naturally more efficient to cut the magnetic flux at a right angle than at an angle.
- Magnets including electromagnets, permanent magnets, and superconducting magnets
- magnets have an attractive force that attracts ferromagnetic materials, and materials with high magnetic permeability are ferromagnetic materials, so it is important to use them effectively without dispersing magnetic flux into the air.
- a ferromagnetic material is used, but the magnetic flux density attenuates in the air in proportion to the square of the distance according to the law of Coulomb.
- the magnetic material is affected by the attractive force, and the higher the magnetic flux density, the greater the attractive force.
- the structure is as follows: from the rotating shaft to the outside, the rotating shaft: electromagnet with yoke ⁇ air gap ⁇ conductive wire fixed to slot ⁇ yoke
- the yoke-mounted electromagnet rotates, the slot-fixed conductive wire and the yoke serve as stators, and the slots are usually ferromagnetic.
- the conductive wire of the power generation unit is stretched parallel to the rotation axis, that is, the magnetic flux of the power generation unit moves perpendicular to the rotation axis, and the conductive wire cuts off the magnetic flux. That) Must rotate by pulling out the attractive force between the stator slot and the ferromagnetic material that constitutes the yoke, which consumes a great deal of energy to generate electricity. is there.
- Japanese Patent Application Laid-Open No. 7-235556 uses only one pole of the permanent magnet, ie, one of the north pole and the south pole, and has a driving magnet array in which only the south pole operates and a DC ON / OFF driving electric circuit. It is assumed that the coil for power generation is wound, but when there is no coil core and when the coil core is non-magnetic, as in the case of the motor coil core, the coil is rectified by the bridge diode. This generator is for AC power generation. For this reason, it is considered that the permanent magnets are arranged with alternating polarities.
- the magnetic flux flows through the coil core while the coil core for power generation passes in front of the permanent magnet, and the coil obtains an electromotive force. Since the attractive force of the permanent magnet acts on the surface, a large rotational driving force is required to rotate the magnetic force by turning off the attractive force. Disclosure of the invention

Another object of the present invention is to obtain a power source by driving the electric motor of the present invention by utilizing the power generation.
- a magnetic circuit is placed parallel to the rotation axis
- a power generating coil is placed on the parallel magnetic circuit at an angle perpendicular to the rotation axis, and the N pole and the S pole are sandwiched. Therefore, Fleming's right-hand three-finger law, the direction F in which the force of the thumb works, acts in opposite directions on both sides of the coil ring for power generation and cancels each other, resulting in zero, resulting in fixing the coil for power generation.
- a non-magnetic material is used to eliminate the attraction by magnetic force, and the motor is installed on the same rotating shaft as the rotating shaft of the power generating coil or on the rotating shaft that transmits power through a transmission mechanism such as a gear. It is a system that generates electricity. Further, the magnetic flux flow of the generator of the present invention, except for the electromagnet that generates an alternating magnetic field for driving, always moves in a fixed direction in the used member, so that no hysteresis loss occurs. No. Furthermore, when two or more parallel power generation coil rings are used, the magnet ring sandwiched between the power generation coil rings can use both the N and S poles simultaneously without using a yoke, so that efficiency is high and expansion is possible. And it is easy to increase the size.
- the present invention is not limited to this, and includes those that can generate a strong magnetic flux, such as electromagnets and superconducting magnets.
- electromagnets When an electromagnet is used, it is necessary to add a power supply line.
- superconducting magnet When a superconducting magnet is used, it is necessary to add a heat insulating layer covering the entire outer box and a device for cooling the entire inside of the box.
- the drive unit is located on the inner peripheral side of the power generation coil unit, but this is not meaningless, and the drive unit may be located on the outer peripheral side of the power generation coil magnet ring.
- the torque is generated by the principle of leverage with the radius of the circumference, so if a drive unit is placed on the outer peripheral side, the required torque changes depending on the ratio of the drive unit to the driven unit. .
- AC power generation there are two types of power generation: AC power generation and DC power generation.
- the AC power generation system of the present invention takes into consideration two types of applications: once rectified to DC and used as it is as it is, and again when it is converted to a suitable AC and used as AC power. Therefore, the AC power generated by the generator according to the present invention does not need to have a sine waveform at all, and adopts a method in which as much power as possible can be extracted from the power generating magnet. This As a result, an AC waveform equivalent to one, which is different from a sine waveform, is obtained, and by rectifying it, a smoother and larger power can be obtained before the smoothing circuit.
- the winding method of the coil for power generation is free at the time of detailed design, but the conventional winding method (whole winding, short winding, concentrated winding, distributed winding, single phase winding, lap winding, wave winding, chain winding, etc.) ), And the choice between single-phase and three-phase power generation and the three-phase correlation method are also at the discretion of the design.
- the drive source of the motor generator according to the present invention similar to the generator, runs a plurality of magnetic fluxes in parallel with the rotation axis, and installs an electromagnet that generates an alternating magnetic field in the magnetic fluxes. It rotates with the driving force and is connected to the power generating magnet or the power generating coil or both rotating shafts, and is a small computer, a system LSI, or an electronic circuit including an inverter controlled by a microphone / processor. Controlled. This control is mainly for rotational speed, rotational torque, rotational direction, rotational synchronizability, and the most economical drive power consumption for power generation.This control responds to power demand for power generation. is there.
- generators of the same size and capacity rotate counter-rotating the generator magnet and generator coil with each other, thereby doubling the power generation capacity at the same speed. It can respond to twice the fluctuations in power demand.
- the number of power generating magnet rings and the number of power generating magnetic paths parallel to the rotation axis can be increased as needed. It can be increased at any time by reducing the time.
- the number of magnet discs, the number of coil coils for power generation, and the number of magnet ring layers for power generation in the circumferential direction depend on the design as required. The larger these numbers, the larger the equipment.
- the magnetic charge varies depending on the dimensional ratio (L / D) and shape of the permanent magnet.
- Cylindrical NSK ® mainly iron, nickel, cobalt, aluminum, titanium, etc.
- other permanent magnets have similar dimensional performance curves.
- NKS-750 to obtain a magnetic flux density of 12 Tesla with a cylindrical magnet, LZD ⁇ 4 is required. In other words, it requires a magnet length four times the diameter of the cylindrical pole used. This would be too large in size and weight to limit its practical use.
- the magnets Prior to magnetization, the magnets are subdivided according to the LZD characteristics, and the pre-magnetized magnets are combined with a strong adhesive, or the magnet side walls are covered with a highly permeable material.
- the magnetic properties of each permanent magnet material can be made 100% by making them magnetically independent, placing them in a mold that matches their shape, if necessary, and molding and magnetizing as necessary. %, And the size of the magnet can be reduced.
- a uniform magnetic flux can be obtained by installing a pole piece at the magnetic pole (one or both sides) on the side where the assembled permanent magnets are used.
- the magnetic flux other than the magnetic axis inside the magnet draws a parabola toward both magnetic poles.
- an egg-shaped permanent magnet is arranged in a container of the desired shape, the gap is filled with a highly permeable material, and pole pole pieces are provided on both poles to create a similar high-flux permanent magnet. be able to.
- the method for enhancing the magnetic force of the permanent magnet is an invention to be used for a generator, a motor generator, and a use other than the generator motor of the present invention.

- magnets equivalent to the power-generating magnet are arranged at the upper and lower ends of the coil so that the magnetic flux flows in the same direction as the power-generating magnetic flux.
- coils are provided on the outermost and innermost circumferences of the power generation coil bundle, and the generated current immediately before being taken out of the generator flows as shown in the illustration, based on the principle of Oersted.
- the generator of the present invention When the generator of the present invention is structurally large, its cross-sectional shape is a disk or a cylinder elongated from the center axis of rotation, and in particular, most of the coil for power generation is a wound coil, and On the other three surfaces, the magnet for power generation and the central rotation axis or their extension are all rotating, so the support structure for the coil for power generation is weak. Easy. Therefore, in the present invention, a non-contact magnetic rotating body support mechanism is provided at the end of the power generation coil unit, and the support structure is further strengthened.
- This non-contact magnetic rotating body support mechanism consists of a hollow disk-shaped magnet body with N pole on one side and S pole on the other side, and the other fixed body at one location fixed to the rotating body.
- the two pairs of magnets are arranged such that the north pole and the north pole of the hollow disk-shaped magnet face the south pole and the south pole faces the south pole.
- the tip of the power generation coil is fixed in a non-contact manner by its loud force or repulsive force.
- the magnets on both sides of the hollow disk-shaped magnet may be hollow disk-shaped magnets. Further, the hollow disk-shaped magnet may be an aggregate of magnet pieces incorporated in a mold.
- the non-contact magnetic rotating body support device using the force of the magnet or the repulsive force of the magnet is an invention to be used for applications other than the generator and the electric motor, which is the main object of the present invention.
- the driving magnets are arranged such that the magnetic poles are alternately arranged along a fixed circumference having the same circular center point as the rotation axis so as to form a single ring, and the magnetic flux layer is parallel to the rotation axis.

- the magnet is fixed and installed so as to sandwich it, and an electric current is passed through the electromagnet to create an alternating magnetic field, and the magnet ring is driven by obtaining the basal force and attractive force to rotate the rotating shaft. Therefore, since the driving electromagnet ring is fixed, there is no slip ring that transmits electricity on the rotating shaft. In the above explanation, the electromagnet ring is fixed, but the power can also be driven by connecting the electromagnet ring to the rotating shaft.In this case, wiring for power supply and a slip ring set are required becomes
- the drive device of the present invention is characterized by a structure in which the drive magnetic flux runs parallel to the rotation axis. For this reason, if the circumference of the drive magnet ring is increased, the drive magnet ring becomes larger in proportion to the leverage principle. The torque can be obtained. Furthermore, the drive magnet ring can be easily multi-layered.In addition, there is a rotating body that has a single-layer or multilayer drive magnet ring on the same rotation axis by connecting the magnetic path. And it is easy to increase the output. In addition, a rotating body having a driving magnet ring is sandwiched between the electromagnet rings. In this case, both poles of the magnet can be used directly without a yoke, which is efficient.

Is what you do. Furthermore, in the case of a motor generator, drive operation control is performed by detecting the difference between the current power generation status and the power demand and inputting data.
- a storage battery For a sudden increase in power demand that cannot be made in time, and for start-up and rapid increase in rotation speed, a storage battery is installed in the system and floating charging is performed, and not only the power demand as output but also the drive unit itself It responds to a sudden and temporary increase in power demand.

Although the configuration shown in FIG. 27B shows two plates vertically, this may be one.
- a rectangular or cylindrical permanent magnet draws a parabola whose magnetic flux moves away from the magnetic axis toward both magnetic poles inside the magnet, so there is leakage of magnetic flux from the magnet side wall. If the magnetic pole positions are opposite when the two domain walls are combined, the magnetic flux forms a loop at the domain wall and returns to the magnetic flux, as shown in Fig. 5, so that the forces attract each other.The direction and position of the magnetic poles are the same. In this case, the force acts to separate the individual magnets.
