Abstract
An electric machine includes a stator and a rotor operable with the stator. The rotor includes at least one pole section, the pole section defining a direct axis in a flux barrier having a first end and a second end. Each of the first and second ends are positioned proximate to the stator. The first end defines a first angular position relative to the direct axis and the second end defines a second angular position relative to the direct axis. The first angular position is different in magnitude than the second angular position to reduce a torque ripple or torque oscillation of the electric machine.
