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


Answer :

The split ring reverses the direction of current in the armature coil after every half rotation due to change in orientation of the magnetic field, i.e, it acts as a commutator. The reversed current reverses the direction of the forces acting on the two arms of the armature after every half rotation and this allows the armature coil to rotate continuously in the same direction.
