The main materials used in carbon brushes are graphite, impregnated graphite, and metal (containing copper and silver) 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 stuck on a metal bracket. There is a spring inside to press it tightly against the shaft. When the motor rotates, the electrical energy is transmitted to the coil through the commutator. Because its main component is carbon, it is called a carbon brush.
