  • Patent number: 12489326
    Abstract: A stator for an axial flux motor having a laminated stator core which is fastened to a flange, wherein the laminated stator core has a rear side which is interlockingly and frictionally fastened to a front side of the flange, and/or a cooling channel between the laminated stator core and the flange is formed in the region of the fastening. An axial flux motor is also provided having a rotor which is arranged between two stators, of which one or both are as described above.

  • Publication number: 20240195253
    Abstract: stator of an electric axial flux machine as well as to an electric axial flux machine. The stator of the axial flux machine includes a plurality of axially protruding stator teeth, a first winding being wound about at least one stator tooth, the first winding being surrounded on at least part of its radially outer face by at least one additional winding. The stator of an axial flux machine and the axial flux machine equipped with this stator afford durable units which combine an axially compact size with high performance.

  • Publication number: 20240195255
    Abstract: An electric machine comprises a stator, a rotor and an air gap between the stator and the rotor. The stator includes a stator member, a stator winding, an insulating coating between the stator winding and the stator member to provide electric insulation between the stator winding and the stator member, and a local depression in the stator member. The insulating coating is disposed in the local depression. The local depression is located on a side of the stator member facing the air gap.

  • Publication number: 20240146134
    Abstract: A stator of an electric axial flux machine as well as to an electric axial flux machine are provided. The stator of the axial flux machine includes multiple axially protruding stator teeth, a first winding being wound about at least one stator tooth, the first winding being spaced from the stator tooth by at least one radial spacing element such that a gap is formed between a radially inner face of the first winding and the stator tooth in order for a cooling fluid to be able to flow therethrough. The stator of an axial flux machine and the axial flux machine equipped with this stator afford durable units which ensure efficient cooling and thus high performance.
