[0002] Motor slip ring, also known as collector ring or collector ring, is an important component in the motor. The main function of the slip ring is to transmit energy and signals between the rotating part and the stationary part of the motor. It consists of conductive ring, tail brush, brush holder, conductive rod, collector ring and slip ring cover. During the operation of the motor, the rotating part of the slip ring moves with the rotating structure of the equipment, while the stationary part is connected to the fixed structure of the equipment.
