A commutator is a rotary electrical switch that periodically reverses the current between the rotor and the external circuit.

Commutators are made up of a set of copper segments that are fixed around the rotor

and is set into the revolving shaft of a DC machine allied to the armature winding.

They are used in DC motors, generators and universal motorsto ensure that the current in the rotor windings always flows in the same direction.

 

In a motor, a commutator applies an electric current to the windings.

A steady rotating torque is produced by reversing the current direction in the rotating windings each half turn.

In a generator, the commutator reverses the current direction with each turn serving

as a mechanical rectifier to convert the alternating current from the windings to unidirectional direct current in the external load circuit.

 

NIDE can manufacture commutator segments,  hook commutator, slot commmutator, plate commutator, Collecting ring collectors for various industrial applications.
