    Abstract: An electric motor includes a main winding coupled to a first line terminal, and first and second boost windings coupled in series to the main winding. A high-speed lead wire is coupled to a first tap between the main winding and the first boost winding, a medium-speed lead wire is coupled to a second tap between the first boost winding and the second boost winding, and a low-speed lead wire is coupled to a third tap after the second boost winding. A start winding has a first end coupled to the first line terminal and a second end. A capacitor has a first end series-coupled to the second end of the start winding and a second end coupled to the second tap. A switch coupled to a second line terminal is configured to couple the second line terminal to one of the high, medium, and low-speed lead wires.

    Abstract: A liner for use for a resilient stator of an electric machine for positioning between teeth formed in the stator. The stator is conformable from a first generally extending shape with opposed spaced apart ends and to a second generally hollow circular shape. The liner includes a central portion for positioning in a cavity between the adjacent teeth, a first end portion for limiting motion of the liner extending from the central portion and adapted to cooperate with a first end face of the stator, and a second end portion extending from the central portion and cooperating with a second end face of the stator, opposed to the first end face. The first end portion limits motion of the liner. The liner is positioned between adjacent teeth when the stator is in the first shape and remains in the cavity when the stator is in the second shape.

    Abstract: A method of controlling an electrical machine. The electrical machine includes a stator having a core and a plurality of windings, and a rotor disposed adjacent to the stator to interact with the stator. The method includes configuring an amplitude value and frequency values of a three-phase alternating current (AC) voltage startup signal having an amplitude and a frequency, providing the three-phase alternating current (AC) voltage startup signal to the plurality of windings, and altering the frequency of the three-phase AC voltage startup signal according to a preprogrammed frequency ramp function defined by the frequency values. The method further includes discontinuing the three-phase AC voltage startup signal after the frequency ramp function has completed, and switching to a back electromotive force (BEMF) control mode after discontinuing the three-phase AC voltage startup signal.
