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..

I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
