Commutator and Brushes on DC Motor

Commutator and Brushes on DC Motor. To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point.The electrical contacts to the rotating ring are called "brushes" since copper brush contacts were used in early motors.
