Abstract: The disclosed embodiments describe a tapped winding stator for use in an electric motor. In some embodiments, the electric motor includes a stator body. In some embodiments, a plurality of teeth that are adjacent in a circumferential direction. In some embodiments, a plurality of slots are formed between the plurality of teeth. In some embodiments, a plurality of coils are mounted in each of the plurality of slots. In some embodiments, the plurality of coils are tapped in a configuration that allows the stator to selectively bypass one or more of the plurality of coils in operation. A plurality of switches are electrically coupled between the configuration and a respective phase supply to the electric motor, each of the switches having at least a first position and a second position.
