why in transformer there is not rotating
fiddl/ magnetic field like motor
Answer Posted / lokeshraj
The construction of a motor is such that the field rotates
the stator and rotor is made cylindrical for this. but in
general the field just fluctuates not rotates which is
needed in T/F.
In induction motor the field rotates and rotor workes as
secondry of t/f.
