What happens if you give supply to the rotor of three phase
induction motor?

Answer Posted / mayank sharma

well this question seems to be incomplete...is rotor is
given the supply alongwith the stator then the machine will
become doubly excited and will atart to behave as
synchronous motor provided the two fields are inter locked.
however if rotor is given supply and the stator is short
ckted then the rotor will move in the direction opposite to
that of rotating magnetic field.
