What is the function of a commutator in a DC motor?

Jadavpur University. The commutator in a DC Motor directs the applied DC voltage/current to the specific coil/coils such that the resultant space flux in the armature is displaced ideally 90deg with respect to the field flux, even though individual coils are rotating along with the armature, thereby ensuring the development of maximum torque.

Function of starter in the DC Motor | Electrical Revolution

Function of starter in the DC Motor. When the motor is overload, overload release coil is magnetize and it lifts the armature to the upward and short circuit the No volt release coil as shown in the figure A. As soon as the no volt coil is short circuited, it demagnetized and releases the starting arm from 'ON' position.
