  • 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.

  • Patent number: 11458583
    Abstract: A suction-extraction attachment for an insertion tool includes a housing, a bearing unit, and a suction-extraction opening. The housing has an end-side opening that is configured to accommodate the insertion tool. The bearing unit is configured to mount the suction-extraction attachment on the insertion tool. The suction-extraction opening is configured to couple the suction-extraction attachment to a suction-extraction device. The end-side opening and the suction-extraction opening form a transporting channel. The suction-extraction attachment is configured to be mounted on the insertion tool via the bearing unit in an axially movable and rotatable manner such that a position of the suction-extraction attachment relative to the insertion tool alters as a drill-hole depth increases.

  • Patent number: 6448764
    Abstract: A method and apparatus for the contactless determination of planarity and a ferromagnetic metal strip during transit of the strip through a strip-processing line or cold-rolling line. Hysteresis loops repetitively impressed in the metal strip and the tangential magnetic field strength is measured at a surface thereof and electromagnetic parameters are determined from the time course of the tangential field strength signal. The parameters are functions of the mechanical stress which is evaluated to determine residual intrinsic stress distribution and then the planarity or nonplanarity of the strip.
