Recently, a type using a permanent magnet has high power generation efficiency or motor efficiency, and can be constructed with a simple structure. Therefore, recently, it has been widely used for industrial equipment. As for the motor / generator, when the rotation speed of the rotor increases as the voltage and current increase, a large centrifugal force is generated in the rotor, and if the rotor cannot withstand the centrifugal force, the rotor is destroyed. Therefore, the motor / generator is required to withstand the centrifugal force of the rotor. Therefore,
The outer periphery of the permanent magnet member constituting the rotor is reinforced by a reinforcing member such as a reinforcing ring, so that the rotor withstands centrifugal force.

を防止するかの課題がある。However, a motor / generator using a permanent magnet has a simple structure and can output a high power, but can generate an excessively large torque at a low rotation speed. Can not. The reason is that
Since the magnetic force of the permanent magnet in the generator is fixed,
This is because the magnetic force at low speed cannot be increased without increasing the size of the motor / generator itself in order to increase the magnetic force. In particular, in the case of a permanent magnet type motor / generator, when rotating at a low speed or stopping at a predetermined position, the rotation cannot be performed smoothly, and the rotational motion in the jerky state, that is, the coking state, may occur. May occur and smooth rotation may not be possible, and there is a problem how to prevent the occurrence of a coking state.

It is conceivable to construct a large generator to generate large electric power and store it in a battery, etc., or to drive a heater or a compressor using the electric power. Alternatively, there is a problem that must be solved for space and the like. In addition, if a rotor using permanent magnets is used, the size and speed can be reduced. However, in places where the operating environment is severe, such as machine tools, the structure becomes complicated and it is difficult to incorporate them into machine tools. It is difficult to establish. In addition, it is preferable that the motor / generator incorporating a small rotor be constructed so that the distance between the permanent magnet and the stator is as small as possible for operation. Need to be cut.

あった。When the rotor of the motor / generator rotates at a high speed, a large centrifugal force acts. Therefore, reinforcement for preventing the permanent magnet from bursting due to the centrifugal force is always required for holding the permanent magnet. Structural ideas for increasing the strength of the magnet are required. In addition, electric
The generator can obtain high output by rotating the rotor at high speed. However, at high speed, there is a problem that the magnetic force of the permanent magnet is too large, back electromotive force is generated, and efficiency is lost. There were problems such as making the element lightweight and increasing its rigidity to withstand high-speed rotation, and necessitating control measures.

り，いわゆるコキングという現象がなくなる。In this high-torque motor / generator, when the rotor, that is, the rotor is started, the rotor is driven by the magnetic force generated by the permanent magnet member so that the teeth of the stator and the permanent magnet member are coaxial in the circumferential direction. Since the torque becomes minimum when the lines are aligned and the torque becomes maximum at the boundary, the rotational motion is not smooth. Therefore, by controlling the magnetic force of the electromagnet and controlling the current flowing through the electromagnet coil of the electromagnet, the rotation fluctuation of the rotor is It can be made smaller and rotated. For example, when operating this high-torque motor / generator as a motor incorporated in a machine tool, etc., the rotating shaft stops smoothly and stops at a predetermined fixed position. When the magnetic force generated by the electromagnet is gradually increased to almost the same as the magnetic force generated by the permanent magnet member, the lines of magnetic force passing through the teeth of the stator can be minimized, and the rotation of the rotor can be reduced. Becomes extremely smooth and the so-called coking phenomenon disappears.

る。In this high-torque motor / generator, when the low-speed torque is increased, the magnetic force of the permanent magnet member consisting of the N pole on the outside and the S pole on the inside of the permanent magnet member smoothly passes through the permeable member. The electromagnetic force from the electromagnet core is added to both ends of the rotor by the S pole on the inner side in the axial direction of the electromagnet core and the N pole on the outer side in the axial direction.
The total lines of magnetic force pass in the same direction and are increased, and the torque is increased. That is, if the controller is set to perform control to energize the electromagnet coil of the electromagnet at low speed, the shaft torque at low speed can be increased.

ができる。Further, when the controller generates a magnetic force of the electromagnet in a direction opposite to the direction of the magnetic force of the permanent magnet member in response to the change of the rotation from the high-speed rotation to the low-speed rotation and the stop of the rotation, the magnetic forces cancel each other. As a result, the magnetic force passing through the stator is reduced, and the rotating shaft is smoothly stopped at a predetermined position, and the rotation at a low speed becomes smooth, so that the coking state does not occur. When rotating at high speed,
Since the magnetic force of the permanent magnet is too large, the torque can be suppressed by eliminating the magnetic force in the opposite direction, and the efficiency can be increased.

に配置されている。Further, since the contact portions of the electromagnet core are in close contact with both end surfaces of the rotor and extend to the position of the reinforcing member and have substantially the same outer diameter as the outer periphery of the rotor. In addition, when the outer side of the permanent magnet member is the north pole and the inner side is the south pole, the electromagnet coil of the electromagnet is wound so that the lines of magnetic force are in the same direction, and the end is in contact with the permanent magnet member and the magnetic path member. The magnetic force flows in the same manner as the permanent magnet. A part of the cylindrical portion is cut out at the side end member of the magnetically permeable material in the opposite direction, so that a magnetic force is prevented from entering. The electromagnets on the other side are arranged so that the magnetic force flows in the opposite direction. That is, the electromagnets are respectively attached to both ends of the rotor so as to form a magnetic force matching the magnetic force of the permanent magnet, and are arranged so as to form respective magnetic force lines.

でき，十分な発電力を確保できる。This high-torque motor / generator responds to a low rotation speed when the controller energizes the electromagnet coil of the electromagnet and increases the magnetic flux by the electromagnet, so that only the normal rotor (rotor) is used. It is possible to produce a torque several times higher than the torque, thereby increasing the low-speed torque which is a drawback of the permanent magnet type motor / generator. Therefore, this high-torque motor / generator can increase the torque at low speeds by increasing the magnetic force of the electromagnet to the magnetic force of the permanent magnet, and the permanent magnet that constitutes the rotor is made of a plurality of permanent magnet members. Then, by forming the cylindrical body and fixing the outer peripheral surface of the cylindrical body by winding up the reinforcing member, the manufacturing cost can be significantly reduced, and the structure can be made simple and high in strength, and sufficient power generation can be secured.
