What are the polishing types of DC motors

An important process that needs to be carried out after the production of a DC motor is polishing. Polishing the surface of the motor can prevent the surface of the motor from being corroded by water vapor, and can effectively extend the service life of the equipment. There are three main types of polishing of this equipment, which are described in detail below.

1. Flame polishing: Use flame to soften and bake the surface of the DC motor. Fire impact can remove some diagonal lines and wrinkles on the surface. After many cuts, the mouth will be flame polished, but this treatment will reduce the DC motor. The flatness of the surface.

2. Polishing with polishing powder: This method is to perform high-speed friction on the surface of the machine to remove scratches. Before polishing, the polishing part must be sanded. This method uses many materials, and the better effect is cerium oxide, but This process speed is relatively slow.

3. Acid treatment and polishing: Use acid to corrode the surface of the DC motor to perform surface treatment. Before polishing the DC motor, it is also necessary to use an abrasive belt to polish, because acid polishing will reduce the thickness of the equipment itself a lot, and it may not be able to all Remove the lines on the surface.

　　 The polishing types of DC motors mainly have the above three points, and the characteristics of each polishing type are also different. Therefore, we should choose the appropriate polishing type according to actual needs.
