I have a table fan of Rallifan Make. When I overhauled it I found a stator winding and an aluminum die cast rotor. So it is supposed that it is a 1 phase induction motor. But there are only two terminals coming out and there is no capacitor. Can any one tell how this motor works? or which type of this motor is?
