Why do permanent magnet motors rust?

Generally speaking, permanent magnet DC motors will rust due to the influence of the external environment after a long time of use. Once the motor shows signs of rust, we need to pay more attention, and do maintenance work in time to prevent more serious corrosion. . So what are the causes of rust spots in permanent magnet DC motors? The following is a brief introduction to Vistar Micro motors.

1. The dirt on the surface of the micro motor is not carefully removed before electroplating

2. The environment where the equipment is used has poor air circulation, humidity or large temperature difference.

3. If the seal of the packaging motor is damaged, the motor will be oxidized, which will cause rust spots on the coating.

4. In the production process of permanent magnet DC motor, the plating time is not enough, which will cause rust spots on the motor coating.

The above is the reason for the rust of the permanent magnet DC motor. I hope our answer will be helpful to you. For more information, please contact us.
