there are a transformer and a motor. both are connected to
3phase, 415 Volt, 50Hz power supply. Both are working with
induction principles. Then, why, motor is rotating and
transformer is not rotating.

Answer Posted / vijay
Even though both works on the same mutual induction
principle,but transformer is a static m/c where as
induction motor is rotating m/c because Indution motors
having rotating magnetic field.
But in the case of T/F, magnetic field generated is satatic
no change in frequency of potential applied, to T/F.
so there is no chance of rotation of T/F.
