What is a carbon brush?

A carbon brush is a part that helps a motor's stationary and spinning components transfer electrical current. In a generator or motor, the fixed carbon brush rides on the rotating commutator, which allows electricity to flow and completes a circuit.

In the beginning, brushes were made of wire and resembled regular wire brushes. However, the wire brushes frequently caused the commutator to wear out and had other run-time problems. Brushes made possible by the use of graphite enabled for a more even distribution of current between commutator segments.

There are four basic grade types of carbon brushes: carbon graphite, electrographitic graphite, graphite, and metal graphite. The needs of the motor or generator and the operational environment are taken into account while selecting the material types. Dimensions, bevels, seats, shunts and terminals, plates and hard tops, and other unique characteristics are used to customise brushes.
