Abstract: A vehicle, electric machine, and method of manufacturing an electric machine include a stator having teeth extending from a yoke portion toward a rotor and defining slots between adjacent teeth with windings positioned within the slots, wherein the slots are coated with an electrically insulating material having an arcuate surface exiting the slots and extending at least partially over the teeth on at least one end face of the stator to form a winding guide for bending/positioning the windings. The winding guide may be formed by a molded epoxy that replaces insulating paper slot liners while providing a template for forming the hairpin bends of end windings.
