Answer Posted / arockia doss.a
Actually the airgap in transformer is for transfer the
primary power to the secondary. Means the primary winding
input voltage level will be step up/down(Depends on type of
trf.) to the secondary winding.
This is exactly same with wats happening in a 3 phase ind.
motor between stator & Rotor.
Thats why we are calling ind. motor as "Rotating Trf".
Thanks ....
