[0002] The carbon brush, also called the brush, as a sliding contact part, is widely used in many electrical equipment. The carbon brush is a device for transmitting energy or signals between the fixed part and the rotating part of a motor, a generator or other rotating machinery. It is generally made of pure carbon plus a solidifying agent, and a sawing machine is needed to cut it during the manufacturing process.
