Supose we have one 220v A.C fan.if we provide 220v D.C what
will be happen?

Answer Posted / p.senthik kumaar

Then, the fan does not rotate.
Because, stator and rotor are seperated by different cycles..
It was phase shifted by 90 degree..
But, capacitor blocks a dc supply.
So, not run..
But, dc produce STATIC MAGNETIC FLUX.
and ac produce RoTATING MAGNETIC FLUX.
So, not possible in induction motor.
It, is possible only in universal motor to run both ac and dc..

Is This Answer Correct ?    1 Yes 2 No
