Question

Explain the difference bw slip rings split rings and commutator

Answer 1

confess, I didn't know the answer.  I only knew that they both were related to commutators in motors.   So I asked Mr. Google and he told me to look at:

where it is stated:
"A split-ring commutator makes the current change direction every half-rotation, whereas a slip-ring commutator merely maintains a connection between the moving rotor and the stationary stator."

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.

Answer 2

A split ring acts as a commutator used in d.c motor to reverse the direction of current.

A slip ring commutator used in A.c. Generator...it is used for producing rotation in the coil.

Hope it helped.
