Generators and electric motors

Abstract

For generators and motors that utilize magnets, in order to reduce the resistance of the magnet's attractive force by utilizing repulsive force, the magnets used to create a repulsive force that matches the attractive force must be of the highest quality with the smallest possible tolerance. However, even with magnets designed for this purpose, it is necessary to confirm whether the attractive and repulsive forces are as designed through post-assembly inspections. If there are any problems, the device must be disassembled, the parts replaced, and then reassembled. If repulsive force is not needed, the related parts must be removed. [Solution] (1) A generator and an electric motor having a rotor in the center with multiple magnets attached at equal intervals around its circumference, a core coil stator with core coils on one side, and a repulsive stator on the other side having magnets that oppose the magnets of the rotor and generate a repulsive force. (2) A generator and motor that replaces the above-mentioned repulsive stator with a movable repulsive adjustment plate and a repulsive base plate, and has an adjuster installed between the repulsive adjustment plates, thereby controlling the repulsive force by adjusting the distance between the rotor and the repulsive adjustment plate.

Description

Technical Field

[0006]

[0001] The present invention relates to generators and motors.

Background Art

[0002] In generators and motors that utilize magnets, in a normal generator or motor where a core coil is arranged in the stator and a rotor having the same number of magnets facing it is rotated, the resistance of the attractive force exerted by the magnets reduces the efficiency. In recent years, with the enhancement of the magnets, the energy consumption due to the attractive force exerted by the magnets has been increasing.

[0003] In Patent Document 1, generators and motors have been proposed that face the magnets of a rotor with a plurality of magnets attached around the rotation periphery, and arrange a plurality of core coils and repulsive force magnets together in the stator to alleviate the resistance of the attractive force exerted by the magnets.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When generators and motors that utilize magnets reduce the resistance of the attractive force by utilizing repulsive force, the magnets that create the attractive force of the magnets and the magnets that create a repulsive force commensurate with it are required to be of high quality with as small a tolerance as possible. However, even for magnets designed, it is necessary to confirm whether the attractive force and the repulsive force are as predicted through inspection after assembly. In case of defects, it is necessary to disassemble the device, replace the parts, and then reassemble it again. Also, when the repulsive force is not required, it is necessary to remove the parts related to the repulsive force. The present invention provides the following generators and motors in order to solve the above problems. Means for Solving the Invention

[0006] (1) A generator and an electric motor, comprising a rotor in the center with multiple magnets mounted at equal intervals around its circumference, a stator for core coils having core coils on one side, and a repulsive stator on the other side having magnets that oppose the magnets of the rotor and generate a repulsive force. (2) Electrical and electric motors that replace the repulsive stator of (1) above with a movable repulsive adjustment plate and a fixed repulsive base plate, install an adjuster between the repulsive adjustment plate and the repulsive base plate, and control the repulsive force by adjusting the distance between the rotor and the repulsive adjustment plate.

[0007] This invention separates a repulsive stator, which has repulsive magnets attached to it to create a repulsive force opposite to the rotor's magnets, from a core coil stator that creates an attractive force. Compared to Patent Document 1, this reduces disturbance and interference of magnetic field lines, allows for quick assembly of the rotor and repulsive stator, reduces the work of replacing and reassembling parts, and allows for the use of the attractive force even after assembly, or adjustment of the repulsive force with an adjuster if the repulsive force is not needed. By making the adjuster hydraulic or electric, brakes and other functions can be quickly controlled, and it can also be used as an instrument to measure the balance between attractive and repulsive forces.

[0009] The rotor 1 of the present invention is a non-magnetic rotating disc that rotates integrally with the rotating shaft 11, and is of the convergent-pole type, in which magnets are aligned with the same poles on one side at equal distances and equal intervals from the rotating shaft 11.

[0010] The stator 3 for core coils of the present invention arranges core coils 4 facing the magnets 2 of the rotor 1, and supports the rotating shaft 11 parallel to the rotor 1 via bearings 10 or the like.

[0011] The repulsive stator 5 of the present invention is a plate to which repulsive magnets 6 are attached and positioned parallel to the rotor 1 on the opposite side of the core coil stator 3, with the rotor 1 in between. In addition, there is a method of controlling the repulsive force by installing a repulsive base plate 8 that maintains a certain distance from the rotor 1 and supports the rotating shaft with bearings 10 or the like, and a repulsive adjustment plate 7 that is movable with an adjuster 9 between the repulsive base plate 8 and the rotor 1.
