Carbon brush is the brush. Features of the electrodes with carbon brushes
Carbon brushes suitable for all kinds of motors, generators, axle machine. Have better commutation performance, long service life.
   Brush for the motor commutator or slip ring, the export and import current slidable contact body, its conductivity, thermal conductivity, and the lubrication performance is good, and has a certain mechanical strength and commutation sparks instinct. Almost all of the motor using a carbon brush, which is a key component of the motor. Widely used in a variety of AC and DC generators, synchronous motor, battery DC motor, crane motor set ring, various types of welding machines and so on. With the development of science and technology, the motor kind of working conditions and the use of more and more diversified, and therefore need to have a variety of different grades of brushes to meet these requirements, it is the type of brush along with the development of the motor industry more and more. People to use and convenient management of many brushes classification. The current classification popular at home and abroad:
1, according to the hard and soft materials can be divided into soft brush, hard brush and a hard brush.
2, according to the use of the object of the brush can be divided into the turbine generator brush, rolling motor useful brush, traction motor brush, brush automobile and tractor, electric tool brush, aircraft electrical power. 3, according to the color of the brush into black brush (made ​​of pure carbon graphite materials) and colored brush (made ​​of copper and other metal materials and graphite).
