Carbon Brush Market size and Key Trends in terms of volume and value 2015-2025: FMI

Rotating electrical devices necessitate the transfer of current from a stationary part to the rotating part of the device. A carbon brush is defined as a sliding contact that is used to transmit current from a static part of a motor or a generator to the rotating part. The name carbon brush originates from the use of a bunch of copper wires assembled in the form a brush which acted as an element that transmitted current to the rotating part of the device. The use of carbon brushes has experienced a wide scale use over the recent past. The properties such as good electrical conductivity, lower coefficient of friction, lower modulus of elasticity and the fact that carbon does not melt but directly passes into vapour phase at nearly 3500oC, has resulted in it emerging as the most preferred material for transmitting current to the rotating part. The most commonly used types of carbon brushes, depending on the material used, are electro-graphite, metal-graphite, resin-bonded graphite, carbon-graphite, graphite among the others.
