A method for operating a pump assembly, wherein the pump assembly has at least one first drive means for conveying a fluid and an electric motor for driving the first drive means, the electric motor comprising at least one stator and one rotor, the rotor being connected at least to the first drive means via a driveshaft. The electric motor draws power at least: i. in order to heat the rotor by means of induction; or ii. in order to drive the rotor, the driveshaft and the first drive means so that these components rotate about a common rotation axis at a speed of more than '' revolutions per minute.

A method for producing a sintered part, having at least the following steps: a) providing a sintered part, said sintered part having a first end face, a second end face arranged at a distance from the first end face in an axial direction, and a circumferential surface between the end faces; b) arranging the sintered part in a tool; c) applying a first pressure force, which acts on the end faces at least in the axial direction, to the sintered part by means of the tool; and d) applying a second pressure force, which acts on the circumferential surface at least in a radial direction, to the sintered part, wherein the sintered part is reshaped at least by the second pressure force, or mechanically processing the sintered part. Steps c) and d) are carried out at least partly simultaneously.

An electric motor, comprising at least a stator, which extends between a first end face and a second end face along an axial direction and has an annular yoke on the first end face and starting from the yoke a plurality of cores, which each extend along the axial direction over a first length to the second end face and are arranged adjacent to one another along a circumferential direction, wherein a coil is arranged on each core, which coil extends starting from the yoke along the axial direction over a second length toward the second end face. The second length is shorter than the first length, so that a portion of each core extends along the axial direction beyond the coil concerned. The motor additionally comprises at least one first rotor which is arranged, at least on the second end face along the axial direction between the coils and the second end face.

A method for producing a green compact uses a pressing tool including a die, a first punch to be displaced in an axial direction, a second punch to be displaced in a radial direction through a channel in the die and a receptacle having a filling opening. The method includes locating the second punch before or during filling of a powdery material into the receptacle so as to be outwardly offset in the radial direction relative to an inner peripheral surface, filling the powdery material into the receptacle, and moving at least the first punch and the second punch and compressing the material in the receptacle, with the second punch being moved in the radial direction toward the receptacle only so far that it is disposed flush with a region of the inner peripheral surface. A pressing tool, a green compact and a sintered part are also provided.

A claw pole stator for a transversal flux motor includes a multiplicity of segments positioned next to one another along a circumferential direction for the annular claw pole stator. Each segment extends from an inner circumferential surface along a radial direction to an outer circumferential surface and is delimited in the circumferential direction by a first side surface and a second side surface and in an axial direction by a first end surface and a second end surface. Each segment is connected by the side surfaces to at least one other segment to form the annular claw pole stator. Segments positioned adjacent each other contact each other by a first contact surface on the first side surface or by a second contact surface on the second side surface and due to the contact surfaces form a form-locking connection in the circumferential direction.
