What is the role of the split ring in an electric motor?

 

Answer

The purpose of split ring is to reverse flow of current after every half rotation of the coil and make coil rotate in a single direction.

If split ring was not used in an electric motor, the coil would have rotated half in clockwise direction and half in anticlockwise direction. 

Note : The split ring is also called commutator.
