A reluctance machine has a stator () and a rotor (). The rotor () comprises an encapsulated body (), which can rotate about an axis of rotation () of the rotor (), and a plurality of flow guide segments (). The flow guide segments () form poles of the rotor (), are arranged in a circumferential direction about the axis of rotation (), and are embedded in the encapsulated body ().

Reluctance machine

A hydrogen recirculation blower is used in a hydrogen return arrangement in a fuel cell system. The blower includes a rotatable rotor with an end region on which an impeller is arranged, and a stator with coil windings and with a hydrogen barrier which is formed as a hollow body. The rotor is arranged in a cavity of the hydrogen barrier, with the hydrogen barrier running both between the rotor and the coil windings and between the impeller and the coil windings. The rotor and the stator form an electric motor for driving the impeller.

A multi-functional spacer element for spacing at least one printed circuit board from an opposite spacing surface. The spacer element can not only accomplish the spacing of one or more printed circuit boards, but can also support a fastening function to a carrier element and an electrical ground connection. A passageway extends through the main body. The spacer element includes a press-in element. The spacer elementincludes an electrically conductive material for electrically conducting from at least a first contact surface to the press-in element.

An assembly () is described for the electrical connection of two components, in particular of a power electronics switch () to an electric motor () of a charging device (), wherein a first component () has a first contact element () made from a conductive material and formed along a longitudinal axis () and designed with an outer surface () at least partially surrounding the longitudinal axis (), and a second component () has a second contact element () made from a conductive material and is designed with a cavity () formed along the longitudinal axis (), whose inner surface () corresponds to the outer surface () of the first contact element (), wherein either the inner surface () of the second contact element () or the outer surface () of the first contact element () is provided with a profile () which has a plurality of projecting elements, wherein the inner surface () and the outer surface () are selected with respect to their lateral dimensions such that the projecting elements of the profile () penetrate in an area close to the surface during insertion of the first contact element () into the second contact element ().

Assembly for the electrical connection of two components

One aspect of the present disclosure relates to a power electronics device for an electrically-driven charging device for an engine, said power electronics device comprising one or more power electronics components which are designed to operate an electrically-driven charging device for an engine, first and second conductors for guiding current for the one or more power electronics components, and a choke for filtering electromagnetic interference. The choke has a magnetic core which forms a closed ring about the first and second conductors and comprises a tongue which extends, arising from the closed ring, between the first and second conductors.
