Permanent magnet motor is a very widely used motor equipment, in cars, elevators many other places have its application, today Xiaobian take you to learn more about the relevant knowledge of permanent magnet motor.

Permanent magnet motor uses permanent magnet to generate the magnetic field of the motor, without excitation coil excitation current, high efficiency simple structure, permanent magnet motor has the advantages of high efficiency, larger specific power, high power factor, high reliability easy maintenance. The variable frequency speed control system with vector control can make the permanent magnet motor have a wide speed range.

In order to prevent rust, the permanent magnet motor generally does rust prevention treatment, but the permanent magnet motor generally in use for a period of time, may be due to environmental factors improper human operation, resulting in rust on the motor, rust will cause corrosion on the surface of the machine, this situation requires timely treatment to prevent corrosion.

So what factors cause the permanent magnet motor rust spot?

1, permanent magnet DC motor in the production process, if the plating time is enough, will make the motor coating rust, which is a problem of the process.

2. Before electroplating, if the dirt on the surface of the motor is carefully removed, it will also cause rust spots on the coating of the motor.

3, permanent magnet DC motor used in the environment of poor air circulation, humidity temperature change is relatively large, will also make the motor coating rust spots.

4. If the seal of the packaging motor is damaged, it will oxidize the motor, then rust the coating.

The above is the reason for the rust of the permanent magnet motor. If the corresponding situation occurs in use, we should deal with it in time to prevent other effects on the motor in later use.
