Bearingless permanent magnet motor for electric vehicle

Abstract

The invention discloses a bearingless permanent magnet motor for an electric vehicle, and relates to the technical field of permanent magnet motors, the bearingless permanent magnet motor comprises a motor main body and a shockproof protection device, the shockproof protection device comprises a shockproof protection cover and a damping base, the shockproof protection cover comprises two arc-shaped plates, one ends of the two arc-shaped plates are connected through a shaft rod, and the other ends of the two arc-shaped plates are fixedly connected through a bolt, and the motor main body is arranged in the shockproof protection cover. According to the motor, the shockproof protection cover is arranged outside the motor main body, the motor main body can be protected so as to prevent the motor main body from being collided and interfered by the outside, the damping base can play a role in damping and buffering the motor main body when the motor main body is impacted, and it is guaranteed that the motor does not generate displacement and the stability of the motor is protected.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a bearingless permanent magnet motor for electric vehicles. Background technique [0002] The motor is a tool that uses the law of electromagnetic induction to convert electrical energy into mechanical energy. It is widely used in industrial production. Due to the rapid growth of economy and technology in recent years, motor companies are increasingly pursuing the small size of the motor. Electric vehicles are also Apply from time to time. The existing motor ignores the function of the motor casing during operation, so that the motor is directly exposed to the working environment, and is easily affected by external collisions, etc., which interfere with the normal operation of the motor. The internal parts of the compact motor are densely arranged, and the large vibration will also cause the motor to move, destroying the stability of the motor, and there are cert...

AI Technical Summary

Problems solved by technology

Existing motors ignore the role of the motor casing during work, causing the motor to be directly exposed to the working environment, and are susceptible to external collisions that interfere with the normal operation of the motor

The internal parts of the compact motor are densely arranged, and the large vibration will also cause the motor to move, destroying the stability of the motor, and there are certain safety hazards
