Question

Difference between split rings and slip rings?

Answer 1

What is the difference between slip ring and split ring in A.C and D.C generators for which A.C and D.C are produced ? A: ... "A split-ringcommutator makes the current change direction every half-rotation, whereas aslip-ring commutator merely maintains a connection between the moving rotor and the stationary stator."

Answer 2

A split-ring commutator makes the current change direction every half-rotation, whereas a slip-ring commutator merely maintains a connection

So, slip rings are useful for DC motors where the current has to change direction every half revolution whereas split rings are used to make constant current connection to a commutator, which is what you want for an AC motor.

hope it helps !
