Untitled Section Which of the statement is true about 3- phase induction motor (IM) ? Ns: Synchronous speed The rotor magnetic field of IM rotates at Ns but stator magnetic field rotates at less than Ns Both rotor magnetic field and stator magnetic field rotates at Ns The rotor magnetic field of IM rotates at the speed less than Ns but stator magnetic field rotates at Ns. Both rotor magnetic field and stator magnetic field rotates at the speed less than Ns The magnitude of the flux in the air-gap of 3-phase induction motor is None Depends on the slip of induction motor Depends on the phase sequence Depends on supply frequency
