The invention relates to an electric machine, comprising a rotor () and a stator (), wherein the rotor () and/or the stator () comprise at least one laminated core () having a substantially rectangular cross-section, wherein the laminated core () comprises a sheet metal strip (), wherein the sheet metal strip () is wound in a coil shape.

Electrical machine

The invention relates to an electric machine, comprising a stator (), a rotor (), a split cage (), which separates a wet region () from a dry region (), control electronics () and an interconnection element (), which produces an electrical contact between the stator () and the control electronics (), wherein the rotor () is arranged in the wet region (), wherein the interconnection element () is surrounded at least partially by an insulating element (), and wherein the insulating element () divides the dry region () into a first subregion (), in which the stator () is arranged, and a second subregion (), in which the control electronics () are arranged.

Electric machine with improved heat management

The invention relates to a DC motorcomprising a cylindrical coil carriercomprising wire guide elementfor guiding a first winding wireand a second winding wireof an air-gap winding on both side end sections, wherein the first winding wireand the second winding wireeach comprise rectangular winding segments, wherein the rectangular winding segmentsof the second winding wireare disposed overlapping on the cylindrical coil carrierand the wire guide elementsare designed for guiding the first winding wireand the second winding wirepast each other.

DC motor having a unique winding structure

The invention relates to an electrical machine (), in particular an electric motor, suitable for the adjustment by external force of elements of a motor vehicle, essentially for driving a steering booster. The inventive electrical machine comprises a rotor () and a shaft (), the rotor having a plurality of plates (), wherein the plates () are premounted on the shaft either individually or as a plate assembly () or by means of a plurality of plate assemblies (), the rotor () being connected to the shaft (). The plates () have resilient lugs () for fixing the plates () and/or plate assemblies () to the shaft (). Furthermore, the plates () of the plate assemblies () comprise centering lugs () which serve to radially center the plate assembly () relative to the shaft (). An attachment of the stator () in a housing part () is possible, wherein centering lugs () at the plates () of the plate assembly () of the stator () serve to center the plate assembly () of the stator () relative to the shaft ().

An electric machine (), particularly used as an electric motor, has a rotor () comprising a plurality of disks (). A disk () of the rotor () is divided in a circumferential direction () into a plurality of disk sectors () between which magnetic pockets () are designed. Furthermore, the disk () has an inner fastening collar () and connecting members () connecting the disk sectors () to the fastening collar (). Such a connecting member () comprises a main web (), a side arm () branching off the main rib () in the circumferential direction (), and a side arm () branching off the main web () opposite to the circumferential direction (). High mechanical stability of the disk () can thus be ensured, wherein magnetic flow losses are reduced.

Electric machine

The present invention relates to an electrical machine including a rotor shaft, a hollow-cylindrical magnet element, a first covering disk, and a second covering disk, in which the first and second covering disks are secured to the rotor shaft, and the magnet element is secured on its first axial end to the first covering disk and on its second axial end to the second covering disk.

Rotor for an electrical machine with improved temperature stability

A rotor for an electric motor having a short-circuit element that has lamination packets in which the laminations of the short-circuit element are embodied with spring elements which press from two sides against permanent magnets of the rotor and as a result center the permanent magnets in the lateral direction independently of production tolerances. After the insertion of the permanent magnets between the spring elements, the short-circuit element with the permanent magnets is potted, for instance with synthetic resin, or spray-coated with plastic. The rotor has the advantage that it compensates for production tolerances of the permanent magnets.
