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
