An electric motor core member includes a body having an inner diametric portion including an inner arcuate surface and an outer diametric portion including an outer arcuate surface. The electric motor core member further includes a plurality of wall members provided on the main body. Each of the plurality of wall members projects outwardly from the outer arcuate surface and is arranged in a spaced relationship to define a plurality of conductor isolation channels. Each of the plurality of conductor isolation channels is adapted to receive one of a plurality of conductors with the plurality of wall members providing electrical isolation between adjacent ones of the plurality of conductors.
