What is the purpose of the commutator in a motor?

On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.

What is a commutator in a generator?

A commutator is a specialized slip ring typically used on Direct Current motors and electrical generators to transfer electrical power between the stationary housing and the rotating armature with the added purpose of reversing the electrical current direction.

What would happen to a motor if its commutator stopped working?

Well, without commutator, the machine will not develop a unidirectional torque and motoring action will not take place. In a DC motor, at the instant when armature coil passes through magnetic neutral axis, current in armature coil must reverse to maintain torque in the same direction.

Can commutator convert AC to DC?

Commutator converts the Alternating to direct current in a DC generator. The alternating current generated in the armature windings of the generator gets converted to direct current after it passes through the commutator and the brushes.

What is the difference between armature and commutator?

An armature is a combination of the winding, commutator, brushes, and ball bearings.



What is Commutator?

Armature Commutator
It produces flux that interacts with the main field to produce armature reaction Due to the armature reaction, the commutator is able is to receive the current from the core winding.

What are the similarities and differences between electric motor and generator?

The Difference Between Electric Motor and Electric Generator in Tabular Form

Electric Motor Electric Generator
The shaft of the motor is driven by the magnetic force generated between the armature and the field. In electric generators, the shaft is attached to the rotor and is driven by the mechanical force.
