Slip ring induction motor carbon brush
A carbon brush is a device that transfers energy or signals between a fixed portion and a rotating portion of a slip ring motor or generator or other rotating machine. It is generally made of pure carbon plus a coagulant. The outer shape is generally a square and is stuck on a metal bracket. There is a spring that presses it on the rotating shaft. For example, after the oil drilling is completed, it needs to be tested. It is necessary to put the instrument from the wellbore, and the signal is sent from the rotating part (the cable drum of the outer steel wire) to the ground instrument through the carbon brush. of. The carbon brush looks a bit like a rubber strip with a pencil and a wire on the top. The volume is large or small. As a sliding contact, carbon brushes are widely used in many electrical equipment. The material of the product mainly includes electrochemical graphite, immersion grease graphite, metal (including copper, silver) graphite.
2. Slip ring induction motor carbon brush functionThe brush motor is placed on the surface of the commutator. When the motor rotates, the electric energy is transmitted to the coil through the inverter. Since its main component is carbon, it is called carbon brush, which is easy to wear. The replacement should be maintained regularly and the carbon deposits should be cleaned.
