Answer 1

Functions of a Commutator in a DC Generator

It converts the internally generated AC into unidirectional DC output. If the commutator is present, then the output will be AC.
Commutation is achieved by periodically reversing the connection of the armature coils to the external circuit.
It maintains a unidirectional current by switching the armature winding segments at the correct time.
It works along with brushes to provide a smooth and uninterrupted supply of power.

The output of the DC generator without the commutator is shown below:
