Single phase AC motors generate a rotating magnetic field using two inductors which are turned on and off sequentially. The second inductor is connected to a capacitor to change the phase angle of the electricity delivered to it. When the supply current is turned on, one inductor is turned on while the other is turned off because most of the supply current is used to charge the capacitor connected to the secondary inductor. When the supply current is turned off, the first inductor is also turned off while the capacitor discharges the electrical energy it has stored and this is used to power the second inductor. The constant on and off alternation between one inductor and another produces the changing magnetic field that rotates the rotor. Is there a single phase AC motor that only uses one inductor to rotate the rotor?
