Abstract:
A stator core assembly for an axial flux electric motor for an automobile includes a cylindrical outer case that defines a central axis, first and second disk shaped insulate frames axially spaced from one another and positioned within the outer case, each of the first and second insulate frames including a circular outer ring, a circular inner ring and a plurality of radial spokes extending between the outer ring and the inner ring and spaced circumferentially about the central axis, and a plurality of segmented core sections extending axially between the first and second insulate frames spaced circumferentially around and supported by the first and second insulate frames, wherein, a radial spoke is positioned between each adjacent pair of segmented core sections, and at least one radial spoke extends across each axial end of each one of the plurality of segmented core sections.
