  • Patent number: 12119709
    Abstract: An axial flux machine, in particular a single-sided axial flux motor, for an electrical machining device, includes a machine shaft, in particular a motor shaft, a disc-shaped stator, and a disc-shaped rotor which is arranged adjacent to the stator in the axial direction of the machine shaft. The stator is formed as a winding carrier for at least one stator winding and the rotor, which is connected to the machine shaft in a rotationally fixed manner, can rotationally moved relative to the stator. The axial flux machine further includes a housing for receiving the stator and the rotor. The housing is cylindrical, open on one side and formed with a substantially closed end face, and the housing fixes the stator in such a way that a defined air gap remains between the rotor and the stator. The axial flux machine can be arranged in an electrical processing device.

  • Patent number: 12088182
    Abstract: An axial flux machine, in particular a single-sided axial flux motor, for an electrical machining device, includes a machine shaft, in particular a motor shaft, a disc-shaped stator, and a disc-shaped rotor which is arranged adjacent to the stator in the axial direction of the machine shaft. The stator is formed as a winding carrier with a plurality of stator teeth for at least one stator winding and the rotor, which is connected to the machine shaft in a rotationally fixed manner, can be set in a rotational movement relative to the stator. The rotor of the axial flux machine has a rotor yoke configured as a bidirectional fan or which is permanently connected to a bidirectional fan by a joining process, the bidirectional fan having at least one radial and one axial air flow direction for cooling the axial flux machine, in particular the stator and the rotor.

  • Patent number: 12062944
    Abstract: An axial flux machine, in particular a single-sided axial flux motor, for an electrical machining device includes a machine shaft, in particular a motor shaft, a disc-shaped stator, and a disc-shaped rotor which is adjacent to the stator in the axial direction of the machine shaft. The stator is designed as a winding carrier for at least one stator winding and the rotor, which is connected fixedly in terms of rotation to the machine shaft, is capable of being set in a rotary movement relative to the stator. Additionally, the stator of the axial flux machine includes a combination of composite materials, in particular fiber-plastic composites, and soft magnetic iron. The axial flux machine can be arranged in an electrical processing device.
