Question

What is the role of split ring in a electric motor

Answer 1

The half-ring D comes in contact with brush A and half-ring C comes in contact with brush B. Hence, the direction of current in the coil MNST gets reversed. The current flows through the coil in the direction TSNM. ... The split rings help to reverse the direction of current in the circuit. These are called the commutator.

hope it helps

Answer 2

Hi

This is your answer.

The split ring in a electric motor is a device which reverse the current after every half rotation. It is also know as commutator. The current is reversed by split ring after every half rotation due to this the coil of the motor rotates in the same direction.
