Carbon brushes for asynchronous motors

asynchronous motor carbon brush Mersen

Mersen metal graphite brushes suited to asynchronous motors

Used in paper and cement plants

Mersen offers a wide range of metal graphite brushes, particularly adapted to asynchronous motors with wound rotor.

Metal graphite brushes grades are prepared from purified natural graphite and metal powders (copper, silver…); then they are compressed and baked to bring them to the required solidity and cohesion levels.
