Abstract
An electric machine includes a core with a plurality of teeth that extends between end faces of the core. Slots are defined in the core between adjacent teeth of the plurality of teeth. The slots each have a radial opening formed between end portions of the adjacent teeth. An insulation sheet is positioned on the core to obstruct the radial openings to the slots. The insulation has at least two spaced circumferential members that respectively overlap the end faces of the core. The insulation sheet also has a plurality of spaced axial members connected to the circumferential members. The axial members are positioned within the slots to obstruct the radial openings to the slots.
