Carbon brushes, also known as brushes, are widely used as a sliding contact in many electrical applications. Carbon brushes in the product application materials are mainly graphite, dipping graphite, metal (copper, silver) graphite. Carbon brush is a motor or generator or other rotating machinery and fixed part of the rotating part of the transmission of energy or signal device, which is generally made of pure carbon and coagulant, the shape is generally square, stuck in the metal stent, which A spring to squeeze it on the shaft, the motor rotates, the electrical energy is delivered to the coil through the inverter, because it is the main component of carbon, called carbon brush, it is easy to wear. Should be regularly maintained replacement, and clean up carbon deposition.
The look of a carbon brush is a bit like a pencil eraser, with leads on the top. The volume is big and small. Brush as a sliding contact, in many electrical equipment has been widely used. The main material products are electrochemical graphite, impregnated graphite, metal (copper, silver) graphite.
