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 / ag
there is no mechanical bearing to support the induction
effect on the transformer secondary winding. So, only
potential(volts) is transferred to secondary for use in
another circuit.
While motor is enable to rotate while being pushed by the
induction effect of the primary because of the mechanical
bearing.
transformer is electrical to electrical
motor is electrical to mechanical
