What is the function of commutator rings in electric motor?

The function of commutator ring in an electric motor is to reverse the direction of current flowing through the coil every time coil just passes the vertical position during a revolution. Hence as the direction of the current is reversed, the torque is changed in the direction.

What is the function of commutator rings in the electric motor Class 10?

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

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.

How does a commutator ring work?

The split ring commutator reverse the current in the armature every half revolution when the commutator changes contact from one brush to another. This reverse in current causes the forces acting on the coil to be reversed. This helps the coil continue to rotate in a clockwise direction.

What is the purpose of the commutator in an electric motor quizlet?

The purpose of a commutator is to repeatedly switch the poles of the electromagnet in the motor.

What is a commutator in a motor Class 10?

Commutator: It is the rotating interface of the armature coil with a stationary circuit. Field Magnet: The magnetic field helps to produce a torque on the rotating armature coil by virtue of Fleming’s left-hand rule. Armature Core: Holds the armature coil in place and provides mechanical support.

What is the difference between commutator and slip rings?

The main difference is that commutator is used for the conversion of AC to DC. … Slip rings are used in AC motors to provide a continuous transfer of power whereas the commutators are used in DC motors to reverse the polarity of the current in the armature windings.

What is the function of split ring commutator in DC motor?

Split ring commutator function in dc motor:

The split ring has the function of reversing the current at that point. When a dc motor shaft comes into contact with a split ring, the split ring reverses the current to maintain the shaft torque in a magnetic field.

What forms the commutator of an electric motor?

Explanation: An electric motor is composed of the following: – Two permanent magnets, which form the stationary part of the motor, known as the stator. – A commutator is a split ring which changes the polarity of the electromagnets, known as the rotor coils.

What is the function of commutator?

The function of commutator ring in an electric motor is to reverse the direction of current flowing through the coil every time coil just passes the vertical position during a revolution. Hence as the direction of the current is reversed, the torque is changed in the direction.

IT\'S FUNNING:  Why does electric current produce a magnetic field?

How does a commutator work in an electric motor?

A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. … By reversing the current direction in the rotating windings each half turn, a steady rotating force (torque) is produced.

Why is a commutator used in a motor?

The commutator assures that the current from the generator always flows in one direction. … 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.
