What is the main function of the commutator?

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.

How is a commutator constructed?

Construction of a Commutator A commutator is built with a set of contact bars and is set into the revolving shaft of a DC machine allied to the armature winding. Once the shaft completes a half-turn, the windings are connected so that current supplies through it in the reverse of the first direction.

What is the function of commutator rings in the electric motor?

Answer: The function of commutator or slip ring is to change the direction of current through the coil after every half rotation.

What is commutator Class 10 Ncert?

Commutator is an attachment, connected with the armature of a motor or dynamo, through which electrical connection is made and which ensures the current flows as direct current. a device for reversing the direction of flow of electric current.

What is the function of commutator in DC motor Mcq?

Commutator is used as mechanical rectifier in DC machines. It converts AC armature current in to DC current. Commutator is used to convert AC current into DC current.

What is a commutator ring?

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 is a commutator describe its purpose?

The commutator can be defined as is an electrical rotating switch in a particular type of generators as well as motors. This is mainly used to overturn the direction of current among the external circuit & rotor. In a DC motor, the commutator provides electric current to the windings.

What is the use of a commutator in DC motor Class 10?

The function of commutator: To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point.
