Purpose of commutator

WebAnswer / vindhya vasini. the function of commutator is to lead current from external stationary leads to the rotating coils of the armature winding in case of motor and to draw current from armature winding to external circuit in case of generator. basically it act as a rectifier as it converts sinusodial (a.c.) signal into d.c signal. WebMay 11, 2024 · Current reversal, is the key role of the commutator as one of the conductive electric motor parts. It ensures that current which flows into the electric motor, is reversed periodically as it flows through the rotor or armature coils. The purpose of current-reversal is to produce a continuously rotating, uniform-directional torque.
