Carbon brushes

Carbon brush leading manufacturer 

A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator.

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. The function of a good brush is explained in more detail in our Technical Data Sheet reference TDS-01.

Mersen offers a wide range of carbon brushes with various designs and grades for all types of motors ‑ from DC motors to asynchronous motors ‑, generators and alternators, grounding devices and current and signal transmission.

Our standard production range meets the requirements of international standards (ISO9001, IEC, NEMA, DIN).
