how to diffrentiate between ac & dc motors from a distance
Answer Posted / p.silamparasan
We can identify the motor its A.C or D.C by their physical
appearance. Basically the A.C motors are shaply in round
because it has only stator winding as 4pole or 6pole. But
the motors are shaply in rectangle because it has poles as
well as interpoles to compensate the flux leakages. So we
can find out a motor it is A.C or D.C by their physical
appearance.
Anybody kindly give me a feedback about my
answere.

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?
