Description of the Related Art Conventionally, there are direct current type and induction type electric motors / generators, and recently, a type using a permanent magnet can obtain high power generation efficiency or electric efficiency and can be constructed with a simple structure. For this reason, it has recently come to be widely used in industrial equipment. In a motor / generator, when the rotation speed of the rotor (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 Since the rotor is destroyed, the motor / generator is required to withstand the centrifugal force of the rotor. Therefore, the outer periphery of the permanent magnet member that constitutes the rotor is reinforced by a reinforcing member such as a reinforcing ring so that the rotor can withstand centrifugal force.

することが必要になる。However, a motor / generator using a permanent magnet has a simple structure and can output a high output at a high speed, but when the rotational speed is small, a too large torque is generated. Can't be issued. The reason is that the magnetic force of the permanent magnet in the motor / generator is fixed, so in order to increase the magnetic force, in addition to increasing the size of the magnet, the motor / generator itself must be configured in a large size to achieve low speed. This is because the magnetic force of cannot be increased. That is, in the permanent magnet, since the magnetic flux generation area is determined by the size of the permanent magnet, if the rotor rotates at high speed, the magnetic flux density increases and the power generation also increases, but if the rotor rotates at low speed, , The magnetic flux density decreases and the power generation decreases. Conventional motors / generators have been developed with various structures for increasing the magnetic force, but there is no definitive one. Also, in a motor / generator, if a rotor using a permanent magnet is used, it is possible to reduce the size and speed, but in places where the usage environment is severe, such as machine tools, the structure becomes complicated and It is difficult to build it in a machine and it is difficult to establish it. Further, the motor / generator incorporating a small rotor is preferably configured so that the distance between the permanent magnet and the stator is as small as possible for operation. For that purpose, it is necessary to cut the outer peripheral surface of the rotor with high accuracy.

There is a problem that cost, production cost, space, etc. must be solved. Since the power generated by the motor / generator is the product of the rotation speed of the rotor and the strength of the magnetic field, the power generated by the motor / generator increases as the rotation speed of the rotor increases. Further, the strength of the magnetic field in the motor / generator is the product of the magnetic force of the permanent magnet and its area. Therefore, in the motor / generator, the larger the area of the permanent magnet and the stronger the magnetic force, the larger the generated power.

た。In addition, since a large centrifugal force acts when the rotor of the motor / generator rotates at high speed, reinforcement is always required to hold the permanent magnet so that the centrifugal force does not cause the permanent magnet rotor to burst. Therefore, structural ingenuity is required to increase the strength of holding the permanent magnet. Further, since the motor / generator can obtain a high output by rotating the rotor at a high speed, the rotor can be made lightweight and the rigidity can be increased to withstand the high speed rotation. There was a problem.

る。The controller for controlling the magnetic force of the electromagnet responds to the low speed of the rotating shaft by energizing the electromagnet coil to add the magnetic force line passing through the electromagnet core to the magnetic force line generated by the permanent magnet member to reduce the speed. The control is performed to increase the torque. Further, the controller controlling the magnetic force of the electromagnet generates the magnetic force line passing through the electromagnet core in a direction of canceling the magnetic force line generated in the permanent magnet member in response to the high speed of the rotating shaft. The coil is energized to control the high-speed torque. Further, the cylindrical portion of the electromagnet core has a structure integrated with the magnetically permeable member.

き，高速トルクを抑制することができる。Since this high torque type motor / generator is configured as described above, it is arranged on the rotating shaft when the electromagnet coil wound in a cylindrical shape on the inner peripheral surface of the magnetic path case is energized by a command from the controller. A magnetic force is generated in the cylindrical electromagnet core, and the magnetic force of the electromagnet is added to the magnetic force generated by the permanent magnet member, so that the low speed torque can be increased. Also, when the rotating shaft is at high speed, the reverse magnetic force of the electromagnet, which is generated by energizing the electromagnet coil in the opposite direction, reduces the magnetic force generated by the permanent magnet member, and can reduce the excessive magnetic force, suppressing high-speed torque. can do.

It can be guided to the magnet piece of the magnet member. If the controller is set to control the energization of the electromagnet coil of the electromagnet at low speed, the axial torque at low speed can be increased.
Also, at high speed, the electromagnet coil is energized in the direction opposite to that at low speed, and high electromotive force at high speed can be reduced.

For example, in the case of four poles, when the outer side of the permanent magnet member is the N pole and the inner side is the S pole, the electromagnet coil of the electromagnet is wound so that the magnetic lines of force are in the same direction, and the end portion thereof is the permanent magnet. It is arranged so as to contact the member and the magnetic path member. The magnet end in the opposite direction is formed by a notch in the electromagnet core so that magnetic force does not enter. As described above, the electromagnets are attached to both ends of the rotor so as to form a magnetic force that matches the magnetic force of the permanent magnet, and are arranged so as to generate respective magnetic force lines.

ることができる。In this high-torque motor / generator, if the controller energizes the electromagnet coil of the electromagnet in response to a small number of revolutions and increases the magnetic flux of the electromagnet, only the normal rotor (rotor) is used. A torque several times higher than the torque can be output, which can increase 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 speed by increasing the magnetic force of the electromagnet to the magnetic force of the permanent magnet.

In addition to being able to do so, the structure is simple and can be constructed with high strength, and sufficient power generation can be secured. That is, since the permanent magnet member is formed of a plate-shaped magnet piece, the cost can be reduced and a long time can be obtained, and the manufacturing can be performed with high accuracy, as compared with the case where the permanent magnet itself is formed into a cylinder. In addition, by selecting the number and size of permanent magnets made of permanent magnets, it is possible to easily manufacture a permanent magnet of a desired size as a whole at a low cost, and according to the size of the permanent magnet, the internal magnetic permeability can be increased. By determining the size of the members and the size and number of external magnetically permeable laminated members, a rotor of a desired size can be easily and inexpensively manufactured.
