Question

Why do we use a commutator in a dc generator?

Answer 1

Answer:

it applies electric current to the windings.

Answer 2

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.
