摘要： Stator for an electric machine has a number N≥3 of phases, a number P≥2 of pole pairs and a hole count q=2, and a stator core, which has two faces and a plurality of slots which are divided into first to L-th layers, where L≥4. The shaped conductors form for each phase first to fourth paths and are arranged in 2·P winding zones, and each winding zone is divided into a first and a second sub-winding zone and each sub-winding zone extends over the L layers. The shaped conductors of a respective path are interconnected by connectors, which connect shaped conductors in adjacent winding zones of the same phase in an alternating manner at the first face and the second face of the stator core, to form a series connection with a first end shaped conductor.

摘要： 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.
