How to maintain carbon brushes? The carbon brush, also called the motor brush, is a small part of the motor, which conducts current between the fixed wire (stator) and the rotating wire (rotor) of the motor or generator. Brushes are usually composed of one or more carbon blocks and can have one or more shunts or terminals. Motors usually contain more than one carbon brush to conduct current. The brushes are divided into five brush series, and each series is suitable for different types of motors and applications. Carbon brushes have three operating parameters: mechanical, electrical, and physical/chemical.

There are many ways to check the problem, the carbon brushes and the motor are operating normally. The first thing to look at is the stability of the carbon brush. Check the gap between the brush holder and the brush, it is stable and sliding correctly. It is also important to check the distance between the brush holder and the commutator slip ring. The brush holder is adjusted correctly and the angle is right. It is also important to check the commutator for signs of wear and the presence of copper powder. Dust can cause high brush wear, machine contamination, commutator/slip ring slotting and brush side grooves. In this case, the method is to clean the motor regularly, and the air filter provides clean air for the motor. We understand electric motors.
