Abstract
A slot liner for a stator and/or a rotor of an electric machine includes a body configured to be received within a stator slot and/or within a rotor slot. The body extends from a first end to an opposite second end and from a first edge to an opposite second edge. The body includes an inner segment and first and second outer segments that extend along the body. The first and second outer segments flank the inner segment such that the inner segment extends between the first and second outer segments along the body. The inner segment includes at least one different material such that a thermal conductivity of the inner segment is greater than a thermal conductivity of the first and second outer segments.
