Regular 3 phase windings for both stator and rotor.I don't
think heating element is provided .A low voltage is applied
to windings with help of a transformer so that a current
equal to or less than full load current is circulated to
warm up the windings .The voltage and capacity of this tr
depends on the rating of the motor.As the stator is normally
delta wound, one coil gets the full voltage and other two
50% each.As you press the start button ,the transformer gets
disconnected or you can switch it off beforehand.

if we convert ampers into kwh or mwh ,which one formula use by us,pls tell me?

Ceiling fan motor wiring Hi, I have 2 ceiling fans broken. The receiver/control units burned out due to lightening. One Harbor Breeze and one Hunter's I took them apart (remove receiver units). Now on both of the motor I see 4 wires coming out from each motor I really want to know the function of each wire. Are there anyway I can test to see which is which? After searching forums I know these 4 wires are from 2 sets of coils inside the motor, one is Start winding and the other is Runing winding I could not find the receiver/control unit any where, so I am planing to buy Capacitors and universal remote controls to make the fans run again. Anyone has any idea how to do the wiring, please help Thnks
