Abstract: A permanent magnet machine is disclosed, including a stator assembly which includes a housing, a stator backiron, a plurality of windings disposed in the housing coupled to a plurality of electrical connections, and a plurality of stator teeth coupled to the stator backiron. The permanent magnet also includes a rotor assembly which includes a center configured to couple to a mechanical coupling member disposed about the center, an inner core, positioned around the center, an outer core disposed around the inner core, and a plurality of outwardly protruding poles radially located within the stator assembly each outwardly protruding pole having an outer surface adjacent to at least one tooth of the plurality of teeth. Each outer surface of each outwardly protruding pole having a rotor tooth extending from the outer core and a permanent magnet disposed next to the rotor tooth.
