Why do motor rotor surfaces need to be painted?

The rotor is a key part of the motor, the surface of the motor rotor are coated with a layer of paint, what is the role of this? Today we will introduce the reason why the surface of the motor rotor should be painted

The rotor of the motor will have a beautiful metallic color just after rotation, but if it is placed in a humid environment or left for a long time, the surface of the rotor will show obvious corrosion, which affects both the appearance of the rotor and the performance of the motor.

In order to prevent surface rust, the surface of the rotor core is painted after processing. In order to protect the motor during manufacture and machining, the rotor must be protected from surface rust. However, condensation that forms in the motor cavity due to temperature changes after the motor stops running can also cause the rotor to rust. Therefore, painting the rotor of the motor is a preventive measure to prevent the motor from rusting.

The above is the reason why the surface of the motor rotor should be painted, for more information please feel free to contact us
