Abstract: A stator assembly has a substantially cylindrical core that defines a plurality of winding slots and a plurality of wedge-shaped insert slots, with the winding slots and insert slots alternating around the perimeter face of the core. Each insert slot is wedge-shaped to receive a wedge-shaped insert. The insert includes a cap at one end that is configured to be positioned at the insert slot opening when the insert is disposed within the corresponding insert slot. The cap includes a pair of wings extending therefrom that are sized and configured to overlap a portion of a winding slot on either side of the insert slot when the insert is disposed in said insert slot. The insert slots and inserts include a feature for locking engagement of the inserts in the slots.
