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 / suresh apgenco
For electro magnetic induction, either field should rotate
or conductor should rotate. if u give 3 phase supply to
motor a stationary rotating magnetic field will set up. as
the field is stationary, rotor starts rotating in motor to
get magnetic induction. butin case of transformer, field is
rotating field will setup but not stationary rotating
magnetic field. as the field is rotating, conductor should
be stationary to get magnetic induction.
