An electric machine includes a housing, a stator core positioned within the housing, a wire wound about the stator core to form a plurality of end-turns that extend from an end of the stator core, and a thermal conductor positioned between the plurality of end-turns and the housing. The thermal conductor includes a substrate and a thermally conductive coating formed on a surface of the substrate. The thermally conductive coating includes a thermally conductive, dielectric material configured to transfer heat from the plurality of end-turns to the substrate.
