Description:
Carbon brush, also known as electric brush, as a sliding contact, is widely used in many electrical equipment. Carbon brushes are mainly made of graphite, grease impregnated graphite and metal (including copper and silver) graphite. Carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of motor or generator or other rotating machinery. It is generally made of pure carbon and coagulant. Its appearance is generally square, which is clamped on the metal support, and there is a spring inside to press it tightly on the rotating shaft. When the motor rotates, it transmits electric energy to the coil through the phase converter. Because its main component is carbon, it is called carbon brush, which is easy to wear. It should be maintained and replaced regularly, and the carbon deposit should be cleaned.
The appearance of the carbon brush is a bit like a rubber strip for wiping a pencil. There are wires on the top. Size varies. As a kind of sliding contact, carbon brush is widely used in many electrical equipment. Product materials mainly include electrochemical graphite, grease impregnated graphite, metal (including copper, silver) graphite.
