Answer:
We must use a commutator in dc generator because it converts direct current into alternating current.
The main function of the commutator is to keep the torque on a dc motor from reversing every time the coil moves through the plane perpendicular to the magnetic field.
Dc commutator is always placed on the rotor. In a motor, the commutator applies electric current to the windings.
Commutators acts like rectifiers to convert the ac signals into dc signals.
