ABSTRACT:
An electric motor includes a stator having a stator core, a start winding and first and second main windings. The first main winding and the start winding are configured to form a lower number of poles than the second main winding. The stator core forms a stator bore. The motor also includes a rotor having a rotor shaft concentrically arranged axially of the stator core and a rotor core positioned concentrically with the rotor shaft. Secondary conductors are arranged axially of the rotor shaft and extend through the rotor core. A plurality of permanent magnets are located at an outer periphery of the rotor core and are magnetized to form a number of poles equal to the number of poles formed by the second main winding.
