If a 3-phase induction motor is fed from the rotor short circuiting the stator terminals, frequency of the current flowing in the short-circuited stator is?
(a) slip frequency
(b) supply frequency
(c) zero
(d) frequency corresponding to the rotor speed
This question was posed to me by my school teacher while I was bunking the class.
My enquiry is from Starting of Polyphase Induction Motors-II topic in section Starting of Induction Motors of Electrical Machines
