Answer:

Explanation:

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.

Commutator is a device which reverses the direction of flow of electric current through a circuit. ... As it reaches the half way, the split ring which acts as commutator reverses the direction of flow of electric current. Reversal of direction of current reverses the direction of forces acting on the coil.
