MOTOR BRUSHES
The electric motors that power your Quantum Dynamo ATS use carbon
brushes. These brushes may become susceptible to wear over a long
period of time. The motor brushes are the two contacts located inside
the motor assembly that supply power to the motor. They are designed
to provide several thousand hours of operation. But if the brushes
become dirty with carbon deposits or wear out, a motor will run poorly
or not at all.
