An axial flux machine and a method for installing an axial flux machine has at least two active parts in a motor housing, of which active parts a first active part is configured as a rotor having a number of permanent magnets and a second active part is configured as a stator having a number of electrical windings, wherein the rotor and the stator are arranged adjacent to each other and in a rotation-proof manner, in a transport configuration in a space-saving package, in particular a stack, formed by the magnetic attractive forces of the permanent magnets.

Method for installing an axial flux machine

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.

Pump arrangement, axial-flow machine and compressor comprising at least one rotor having permanent magnets and a stator having a multiplicity of teeth separated from each other wherein the tooth tip has a substantially rectangular-shaped cross section

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.

Stator arrangement for an axial-flow machine

The invention relates to a method of closing a bore () in a metal sintered component (), whereby, prior to sintering a preform () to obtain the sintered component () or before a step of calibrating the sintered component (), a closing body () is pushed into the bore (), and the closing body () has an external diameter that is either of an identical size to or at least partially larger than the internal diameter () of the bore ().

Method of closing a bore

The invention relates to an assembly () having at least two metallic components () which are subject to sliding stress and each have a sliding surface and in operation slide against one another, wherein at least one of the components () consists of a metallic sintered material having an iron-based matrix containing iron together with carbon and up to 10% by weight of at least one non-ferrous metal at least in the region of the sliding stress, where the carbon content is at least 1% by weight and not more than 10% by weight and at least part of the carbon is present in unbound particulate form in the matrix.

Component having reduced metal adhesion

The invention describes a method of producing a sinter-hardened component from a metallic powder containing chromium which is pre-alloyed in particular, comprising the steps of compacting the powder to form a green compact and then sintering the green compact in a reducing sintering atmosphere at a sintering temperature in excess of 1100&#xb0; C. A gas containing carbon is added to the sintering atmosphere.
