Abstract
An electric machine includes a stator and a rotor core positioned adjacent the stator and rotatable about a longitudinal axis. The rotor core includes a plurality of bar apertures, a plurality of elongated flux barriers separate from the bar apertures and positioned radially inward of the bar apertures, and a plurality of magnet slots separate from the bar slots and positioned radially inward of a portion of the bar apertures. The electric machine also includes a plurality of magnets, each positioned in one of the magnet slots. A plurality of conductive bars are each positioned in one of the bar apertures and includes a first end and a second end. A first end ring is coupled to the first end of each of the bars and a second end ring is coupled to the second end of each of the bars.
