Abstract: A stator arrangement for an axial-flow machine includes a stator having stator teeth circumferentially distributed concentrically and axially separated from a rotor by an air gap. The stator teeth have two axially-opposite end portions and a tooth core therebetween. Each tooth core is wound with at least one coil winding. The first end portion facing the rotor forms a tooth tip having a tip cross-sectional area larger than the core cross-sectional area. The second end portion, turned away from the rotor, forms a tooth root, having a root cross-sectional area, which is joined to a reflux plate. The tooth tip of each stator tooth as well as the reflux plate respectively has at least one recess for at least one tooth securing device, and each stator tooth is securely joined by the at least one tooth securing device to the reflex plate in at least axial direction.

Abstract: A pump arrangement includes an axial-flow machine and a drive to convey fluid mounted in a housing. The axial-flow machine is formed by at least one first rotor having permanent magnets, a shaft connected to the first rotor and a stator arrangement with stator teeth distributed concentrically around the shaft axis circumferentially and axially separated from the first rotor by an air gap. The stator teeth have axially-opposite end portions and a tooth core therebetween wound with at least one coil winding. The second end portion, turned away from the first rotor, of each stator tooth forms a tooth root joined to a back plate. The first rotor is an eccentric disk and on the side away from the stator arrangement has an eccentric cam, radially spaced from the shaft axis, and rotatably and torque-transmittingly connected to the drive. An axial-flow machine and a compressor includes the pump arrangement.

Abstract: An axial flux motor is disclosed, with at least one rotor, with at least one stator that has a stator yoke and at least one stator tooth made of a soft magnetic powdered material, which stator tooth has a tooth neck and a tooth head that adjoins the tooth neck and constitutes the pole face of the stator tooth, and with a fastening means that comprises at least one mechanical connecting element, which connecting element fastens the stator tooth to the axial flux motor. In order to embody this in a durable way, it is proposed for the stator tooth to have a fastening opening, which, starting from the pole face of the stator tooth, passes through its tooth head and tooth neck, with the mechanical connecting element being accommodated in the fastening opening in countersunk fashion relative to the pole face.

Abstract: An arrangement has at least one electrical winding having a one-part or multi-part component produced from a soft-magnetic powder composite material, which component conducts an electromagnetic flow of the winding, at least in certain regions, and has a recess provided in the region of this flow conduction, and having a one-part or multi-part, particularly metallic connector part, which has a greater mechanical strength and/or electrical conductivity and/or thermal conductivity as compared to the component, and projects into the recess of the component. In order to achieve particular thermal, mechanical and/or electrical properties, the recess penetrates the component in the region of its flow conduction, and the connector part that projects through this recess forms a mechanical, electrical and/or thermal bridge that bridges the component.
