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 / dindo
it simply because the motor has rotating core.It rotates
only due to the attraction n repulsion of the induced
magnets around in the stator while the transformer have
stationary core only that provide stable and variable supply
through electromagnets.
