Abstract
A motor assembly comprises an electric motor and a motor controller. The motor includes a stator; a rotor; a main winding; a first auxiliary winding; a second auxiliary winding; a capacitor; a first tap point between the main winding and the first auxiliary winding; and a second tap point between the first and second auxiliary windings. The motor controller may energize the first tap point so that the first and second auxiliary windings are in series with the capacitor and the first and second auxiliary windings and the capacitor are in parallel with the main winding to provide a relatively higher motor speed or may energize the second tap point so that only the second auxiliary winding is in series with the capacitor and the second auxiliary winding and the capacitor are in parallel with the main winding to provide a relatively lower motor speed.
