[0002] The motor carbon brush is an important component in the motor. Its main function is to provide current conduction between the motor and the rotating part when the motor is running to ensure the normal operation of the motor. In the motor, the carbon brush is usually installed on the motor shaft together with the brush holder, and transmits current by contacting the rotating part of the motor. Since the carbon brush constantly rubs against the armature surface during the operation of the motor, it will cause wear.
