Permanent magnet motor bearings refer to the components of the supporting shaft installed on the permanent magnet motor, whose role is to support the motor rotor, reduce friction and wear, and ensure the normal operation of the motor. Permanent magnet motor bearings are usually made of high strength, high hardness and high wear resistant materials, such as cemented carbide, steel, ceramics and so on. The selection and installation of bearings is very important, which directly affects the performance and life of the motor. Under special conditions such as high speed, high temperature and high load, the service life and stability of permanent magnet motor bearings may be affected, so regular testing and maintenance are required..syi
