Abstract
An electric machine may include an adjacent pair of laminations each defining pockets having permanent magnets arranged therein to form magnetic poles. The laminations may be stacked in a pole-skewed fashion to form a portion of a rotor. A stator may surround the rotor. The machine may further include a separator lamination between the adjacent pair defining cutout portions having a shape based on a superposition of shapes of the pockets to increase a reluctance of leakage paths between the permanent magnets.
