[0002] Carbon brushes, also known as brushes, are sliding contacts that are widely used in many electrical devices. The main materials used in carbon brushes are graphite, impregnated graphite, and metal graphite. Carbon brushes are devices that transfer energy or signals between the fixed part and the rotating part of an electric motor, generator, or other rotating machinery. They are generally made of pure carbon and a coagulant. They are generally square in shape and are stuck on a metal bracket. There is a spring inside that presses it tightly against the rotating shaft. When the motor rotates, the electrical energy is transmitted to the coil through the commutator.
