Abstract

Carbon brushes transfer electric current from the motor housing to the commutator on the motor shaft. The motor shaft is stationary. The commutator spins rapidly when the motor is on. Carbon brushes are continuously worn down where they meet the commutator. Worn carbon brushes can be too short to reach the commutator. Worn carbon brushes cannot transfer electric current. Worn carbon brushes cause motors to turn slowly or not at all. Worn carbon brushes must be replaced. Carbon brushes come in various sizes. Brushes for small motors are usually 1.5 cm long and 0.5 cm wide.
