Abstract:
An axial flux electric motor includes a housing including an inner surface and a stator fixedly mounted in the housing. The stator includes a plurality of stator segments each supporting a winding, an inner support member defining a central passage, and an outer annular member constraining the plurality of stator segments. The outer annular member includes an outer surface portion abutting the inner surface of the housing. A thermal connection system is disposed between the outer surface portion of the outer annular member and the inner surface. The thermal connection system transfers heat from the stator into the housing.
