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.
