BRUSHES

What is the purpose of carbon brushes?

A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator, and, as regards DC machines, ensuring a spark-free commutation. Five brush grade families are used for brush manufacturing

How do I know if my carbon brushes need replacing?

To test your carbon brushes, monitor themuntil they are worn down to around a quarter of an inch, as this is usually a good time to replace them. If the brush displays signs of breakage, crumbling or burning the motor will spark, and electrical contact may be incomplete.
