The invention relates to a differential or transfer gearbox () in a motor vehicle, a method of production and the use of the differential or transfer gearbox (). The differential or transfer gearbox () comprises a differential case () in which differential side gears () and differential gears () are accommodated. Each differential side gear () drives a first axle shaft () or a second axle shaft (). A ring gear () is driven by an input shaft () and mounted for conjoint rotation with the differential case (). The ring gear () is interlockingly connected to the differential case () of the differential or transfer gearbox ().

A processing system includes a processing unit configured to process a cartridge, in particular a microfluidic cartridge, and is further configured to process a biological sample received in the cartridge. The processing unit includes a computing unit configured to compare input or read in sample data with input or read in first cartridge data in order to determine a compatibility of the sample with the cartridge. The computing unit is further configured to output a first error message in response to a determination of incompatibility between the sample and the cartridge. A method includes using the processing system to determine a compatibility between a sample and a cartridge.

Cartridge for an analysis unit

A holding element () for attaching magnets () to a rotor () of an electrical machine (). This electrical machine is, in particular, designed as an AC generator and comprises intermediate spaces () between the individual poles (). The holding element () comprises a top side () and spring lugs () which axially fix the magnets (). The holding element () has claw-like projections () which bear against flanks () of the poles () when the holding element () is in the fitted state.

Holding means for electrical machines

The invention relates to an electric machine (), in particular a generator for a motor vehicle, comprising an exciter system composed of a plurality of electrically excited salient poles. The salient poles can be designed within the stator () or rotor () in the form of electromagnetically excited poles () which are axially and radially oriented on the periphery and are alternatively polarized in the peripheral direction. In order to improve performance and reduce the magnetic leakage flux, permanent magnets (), which are secured by means of a magnetically non-excitable holding element (), are inserted into interstices () between the alternating poles (). The holding element () is bilaterally mounted in pole grooves (), is radially, axially, and tangentially resilient, and has a wave-shaped () and/or bead-shaped () profile.

Device for fixing magnets

The invention relates to a winding body for an electric motor and, in particular a brushless direct current electric motor () with an air gap winding. At least two bobbins () per stand () are provided. The invention also relates to a method for the production of said winding body. According to the invention, the bobbins () of a strand () of the winding body () are wound immediately behind each other.

The invention relates to an electric motor having a stator and a rotor in a housing, wherein the stator comprises a plurality of lamellae that are disposed in parallel and are combined into a package. The lamellae are held together via a spring clamp, which overlaps the lamella package in an axial manner, wherein the spring clamp simultaneously supports the lamella package radially on the interior wall of the housing.

Electric motor

An electric mains-connection device for an electric hand-held power tool equipped with an electric motor (M), in particular for an angle grinder, has mains-connection terminals for a mains-connection cable, and with an anti-interference capacitor; it is designed as a mains-connection module that can be actuated externally, includes mains terminals, houses the anti-interference capacitor, and out of which an electric cable extends, which serves to connect motor electronics and a motor switch in an interface-free manner. An electric device for an electric hand-held power tool equipped with an electric motor, in particular for an angle grinder, includes the electric mains-connection device.
