Question

What is the role of split rings in a motor and generator

Answer 1

The split ring in the electric motor also known as a commutator reverses the direction of current flowing through the coil after every half rotation of the coil. Due to this, the coil continues to rotate in the same direction.

Split rings are used in rotating electrical assemblies to make a continuous electrical connection between stationary and moving conductors. This enables the stationary power source to transmit electrical power to the rotating component.

Basically, a slip ring is a band of electrically conductive material mounted on a shaft. Although insulated from the shaft itself, the slip ring is connected to the rotor or rotating assembly through windings or other electrical connections. The outer part of the slip ring is in continuous sliding contact with stationary brushes or other stationary conductors.
