This is achieved by passing electrical current between the motor’s stationary and rotating wires. A carbon brush may have one or more carbon blocks and one or more shunts or terminals. There are often multiple carbon brushes in a motor or generator.

How do you get carbon brushes to last longer?

How do I choose a carbon brush grade?

It’s an important factor in the choice of a carbon brush grade. Water is a critical component of commutator/slip ring films, and is supplied by ambient air. For best performance, a humidity range of 8 to 15 g / m3 (0.008 to 0.015 oz/ft3) of air should exist.
