A method for improving thermal conduction in a stator having electrically conductive windings wound in a plurality of gaps formed between adjacent pairs of a plurality of teeth of the stator. A plurality of interstitial spaces are formed within each of the gaps during winding of the electrically conductive windings around the teeth. A plug is arranged within each one of the gaps to close off slot openings. A thermally conductive filler compound is injected into each gap under sufficient pressure to at least substantially fill the interstitial spaces within each gap and to at least substantially encapsulate the electrically conductive windings. The thermally conductive filler compound is then allowed to set.
