The essential difference between an AC generator and a DC generator is that:

AC generator has slip rings while the DC generator has a commutator

AC generator has an electromagnet while a DC generator has permanent magnet

DC generator will generate a higher voltage

AC generator will generate a higher voltage

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

Commutator or split ring changes the direction of current in the coil of the electric motor, after every half revolution. Note: Split ring is also known as commutator. The function of commutator rings is to reverse the direction of current flowing through the coil every time the coil just passes the vertical position during a revolution.
