) why transformer cannot rotate though the principle behind induction motor is similar to a transfor..

Answer / siva swarup

cool,
an induction motor's rotor is compared as the short
circuited secondary of a transformer. If rotor is blocked
the magnetizing current will increase and saturates
resulting burning of stator.

now why transformer doesnt rotate
1. the secondary of a transformer is not shorted, although
it is shorted through load, the induction is not generated
by synchronously rotating mmf
2. in order to rotate, it require a synchronously rotating mmf
which is not present
3. Rotor is rigid, i.e. its not allowed to move or rotate
(no Bearing suspension provided)

Answer / bibek mukherjee

though the basic principle behind induction motor is similar
to a transformer but the reason to use a transformer is to
step up or down the voltage level in desired lvl. which is
different for a Induction Motor.
Moreover the losses for a rotating unit will
increase....efficiency will decrease...out put will come
down...for a transformer it is not desired...
