Also known as a motor brush, a carbon brush is a sliding contact that is used to transmit an electrical current from a static to a rotating part in a generator or motor. In DC machines, a carbon brush ensures a spark-free commutation. They can be made of one or more carbon blocks, and come equipped with one or more shunts or terminals.

The choice of a carbon brush is important to ensure a proper operation combining the best brush life with respect of the commutator or slip ring. Carbon brushes are maintained by brush-holders to be in permanent contact with the slip ring or the commutator.
spark-free commutation. Five brush grade families are used for brush manufacturing. Each of them corresponds to a specific requirement and has its own production process (see pages 9 to 17 of this guide). The carbon brush plays an essential part in the operation of electrical machines.
Spring carbon brushes help reduce the noise and vibration that can occur during motor operation. The smooth contact between the brush and the commutator or slip ring, facilitated by the spring’s consistent pressure, leads to quieter operation and reduced mechanical stress on the system.
They can be defined as the element which makes the connection between the static part and the moving part inside an electric motor (rotor). Brushes for electrical motors are elements which it´s intended use is to put the required pressure over the collectors or the rotatory rings, hence the contact can be made for the electrical current.
The carbon brush has to be guided by a brush-holder of suficient height and with an adequate clearance to avoid either the brush getting stuck or the brush rattling in the holder. Tolerances and clearances are set by the International Electrotechnical Commission (I.E.C.). (See Technical Data Sheet TDS-04*).
