Claim Text:
1. An electric motor comprising: a conductive winding including a plurality of turns, a first terminal, a second terminal, and a third terminal, wherein a first number of the plurality of turns are between the first terminal and the third terminal, a second number of the plurality of turns are between the second terminal and the third terminal, and the first number is different from the second number; a switching device configured to selectively conduct power from the AC source to the first terminal in a first state and the second terminal in a second state, wherein, with the switching device in the first state, the conductive winding generates a first magnetic field responsive to the AC source conducting power to the first terminal, and wherein, with the switching device in the second state, the conductive winding generates a second magnetic field responsive to the AC source conducting power to the second terminal; a rotor configured to magnetically interact with the first and second magnetic fields generated by the conductive winding such that a torque is applied on the rotor; and a controller configured to:
