Abstract
An electric machine includes a rotor, a first stator, and a second stator. The rotor includes a rotor core and a first and a second plurality of poles mounted to extend radially from the rotor core. The first stator and the second stator each include a stator core, a plurality of teeth mounted to extend from the stator core, and a plurality of permanent magnets mounted as first spokes within the plurality of teeth. The stators are mounted radially relative to a first side of the rotor and separated by a first air gap between the plurality of poles and the plurality of teeth. At least four windings are connected in series and wound about the plurality of teeth. A first flux linkage in a first pair of series connected windings is a mirror image of a second flux linkage in a second pair of series connected windings.
