  • Publication number: 20250149945
    Abstract: An electrical axial flux machine, in particular for a drive train of a hybrid or fully electrically operated motor vehicle is provided. The axial flux machine includes a stator having a plurality of stator coils distributed over the circumference of the stator; power electronics for supplying current to the stator coils; and a high-voltage terminal for establishing an electrical connection between the stator coils and the power electronics. Busbars are located above the stator coils, in the radial direction. The busbars enclosing, in an annular manner, the stator and/or a rotor that can be rotated relative to the stator, and electrically conductively connecting the stator coils to the high-voltage terminal.

  • Publication number: 20250149954
    Abstract: An axial flux machine includes a rotor mounted rotatably relative to a stator. The stator has at least one first disc-shaped stator body, and the rotor and also the first stator body are arranged such that a first magnetically active gap running in a radial plane is formed axially between the first stator body and the rotor. The stator is surrounded at least in portions by a motor housing; a ring-segment-shaped groove which is open towards the first stator body and extends in a radial plane is formed; and a plurality of cooling openings are provided in the motor housing in the region of the ring-segment-shaped groove, by means of which cooling openings a cooling fluid that can be introduced into the ring-segment-shaped groove can be applied to the first stator body.

  • Patent number: 12046967
    Abstract: A stator for an electric machine, comprising a stator core and a stator winding, wherein the stator core has a plurality of slots, which are spaced apart in a circumferential direction and have a depth running in the radial direction, and allows the arrangement of slot sections of the stator winding in a plurality of radially spaced-apart radial positions, wherein the stator has a strip-like winding unit comprising a first and a second winding conductor, wherein the two winding conductors run in a first and a second layer of the winding unit and each comprises: a plurality of straight slot sections which run in a transverse direction of the winding unit and are arranged in parallel, a plurality of first bent end sections which each interconnect two slot sections of the associated winding conductor and are arranged on a first longitudinal side of the winding unit, a plurality of second bent end sections which each interconnect two slot sections of the associated winding conductor and are arranged on a second l
