Rotary disk powered permanent magnet motor

Abstract

A rotary disc power-supplying permanent-magnetic motor comprises a plurality of pairs of permanent magnetic poles mounted on the inner wall of a housing and a plurality of wheel-shaped frames. Bearing holes are formed at the centers of left and right bearing covers connected to two ends of the housing and are provided with ceramic bearings serving as two simple support of a rotor spool; one side of the rotor spool is provided with a stacked iron core provided with an armature coil in an embedded manner, the other side is provided with a plurality of power supplying discs made of insulated materials, the power supplying discs are provided with alloy rings which are connected to a plurality of power transmitting cups through a plurality of hollow rollers, the power conducting cups are connected to a plurality of wiring terminals, power is transmitted to the armature of a motor body through the power transmitting cups, the hollow rollers and the alloy rings of the power supplying discs, and the rotating torque is produced by the force of the permanent magnetic field and the rotating magnetic field in the working air gap to drag the rotor of the motor body to output the rotating torque. The strength of the permanent magnetic field of the motor is easy to detect, adjust and excite, a brush mechanism is omitted, electromagnetic sparks are eliminated, and the rotary disc power-supplying permanent-magnetic motor has multiple using function and long service life and is particularly adaptive to serving as a drive motor of an electrical vehicle.

Description

Technical field [0001] The invention relates to a permanent magnet motor, in particular to a rotating disc power supply permanent magnet motor. Background technique [0002] As we all know, in 1831, Faraday discovered the phenomenon of electromagnetic induction, which laid the basic theoretical foundation in the history of motors. In 1833, the French inventor Pixie manufactured the world's first rotating magnetic pole DC motor. A generator is a device that converts kinetic energy into electrical energy, and a motor is a device that converts electrical energy into mechanical energy. A permanent magnet motor is an electrical machine that relies on permanent magnets as its magnetic field. The permanent magnet motor has good mechanical characteristics and adjustment characteristics: small size, high efficiency, wide range of speed variation, and large starting torque. The DC motor is characterized by the use of a commutator and a brush mechanism. The disadvantage is that when...

Problems solved by technology

The DC motor is characterized by the use of a commutator and a brush mechanism. The disadvantage is that when using a carbon brush, especially a carbon brush made of adhesive carbon powder, due to the existence of the adhesive, the current accompanied by the magnetic field energy When the commutation is delayed, the excess energy is forcibly released in the form of electromagnetic sparks. The electromagnetic waves will cause greater interference to the surrounding electrical appliances, and will also cause the surface of the carbon brush and commutator to burn, and the carbon brush will be stuck due to expansion. It cannot conduct electricity in the brush groove, resulting in shutdown failure, and the friction between the carbon brush and the commutator will generate running noise, so the working life of the motor is short

AC asynchronous motor has simple structure, reliable operation, cheap price, no electromagnetic sparks, no interference to surrounding electrical appliances, low operating noise, convenient use, installation and maintenance, low manufacturing cost, and AC motors can be directly connected from the mains Or the frequency converter has the advantages of power supply; the disadvantages are: large volume, low energy conversion efficiency, cumbersome technical means of speed regulation, expensive price, poor mechanical characteristics, and small starting torque

The disadvantages are: compared with the brushed motor, the electromagnetic torque fluctuates greatly, and the power supply circuit is more complicated, so the manufacturing cost is higher. Because the rotor is a permanent magnetic pole structure, the performance of the magnetic pole material and the space inside the motor cavity limit this. The structure of similar motors is not conducive to the manufacture of higher power motors

The high-voltage motor has a strong ability to resist abrupt current shocks, but it is difficult to control when starting and braking
