Answer 1

Explanation:

What is Split Ring?

The split ring in the electric motor is also known as a commutator that consists of a simple ring or cylindrical shell which is split axially with the parts insulated from each other.

Role of Split Ring in an Electric Motor

Split ring is used for reversing the direction of current in the coil. For the continuous rotation of the coil in the same direction, the current in the coil must be reversed. Therefore, after every half rotation of the coil the direction of the couple rotating the coil remains the same and the coil continues its rotation in the same direction.
