Expert Answer:
Dear Student
The commutator is really just a switch. As it rotates, it changes the direction of the electricity in electric motors and generators. By reversing the electricity flow in an electric motor armature (moving coil) a rotating force is produced which in turn rotates the armature and converts the electrical force to mechanical force. In a generator, the commutator does exactly the reverse; it converts the mechanical force to electrical force.
Hope that satisfies your query.
