brushes

brushes   Role in the motor is to change the direction of the current sub-DC and AC motors, DC motors are used to change the conductive coil rotor, thus changing the rotor poles. Thus changing the movement of the motor. Carbon brushes for the motor commutator or slip ring, as the export import current slidable contact body, its conductivity, good thermal conductivity and lubricity, and has a certain mechanical strength and commutation sparks instinct. Almost all of the carbon brush motors are used, it is an important component part of the machine. Brushless motor for a variety of motors, generators, axle machine. Has good commutation performance, long service life. Brushless motor for the motor commutator or slip ring, as export and import current sliding contact body, its electrical conductivity, thermal conductivity and good lubricating properties, and has a certain mechanical strength and commutation spark instinct. Almost all of the carbon brush motors are used, it is an important component part of the machine. Widely used in a variety of AC and DC generators, synchronous motor, battery DC motors, crane motors collector ring, various types of welding and so on. With the development of science and technology, the type of motor and working conditions using more diverse, and therefore need to have a variety of different grades of brushes to meet these requirements, it is kind of brushes with the development of the motor industry and more and more.
