The relative speed between the stator magnetic field and stator in the induction motor is ______(a) Ns(b) Ns-Nr(c) Ns+Nr(d) 0I got this question during an online exam.I'd like to ask this question from Induction Motors in section Braking of DC Motors & Induction Motors of Electric Drives

Answer»

Correct option is (a) Ns

For explanation I would say: In Induction MOTOR STATOR magnetic field rotates at the SPEED of synchronous speed. The stator is MADE up of Silicon STEEL and remains at rest. The relative speed is Ns-0 = Ns.
