- 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:
