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.
Difference Between Slip Ring and Split Ring
|Slip Ring||Split Ring|
|The transfer of power between the rotating and the stationary structure of an AC machine is done using slip ring||The direction of current can be reversed by using split ring|
|It is used in AC machine||It is used in DC machine|
|It has a continuous ring||The ring is split into two or more parts|
|It finds application when power is supplied from an AC generator to the AC motor||It finds application when pulsating voltage is supplied to the DC motor|
