A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part, in a motor or generator, and as regards DC machines, ensure a spark-free commutation.

Carbon brushes are maintained by brush-holders to be in permanent contact with the slip ring assembly or with the commutator. Tripund Energy offers a wide range of carbon brushes for all types of motors, generators and alternators, grounding devices and current and signal transmission.
