is commutator present in ac motor?
Yes, universal motors as used in mains powered tools, drills, sanders etc. not only but also, special type motors. Try 2 sites below.
I guess the answer is sometimes. I forgot about the universal motor the answer is right there induction motors, the largest group of ac motors do not need commutators. depending on whether they have wound or squirrel cage rotors, they may not even need slip rings.
