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 present invention relates to a stator assembly for an electrical machine, including a housing and a stator, in which the housing has at least one inward-oriented bead extending in the axial direction.

Stator assembly for an electrical machine

The present invention relates to an electrical machine, in particular an electric motor, with a housingand coversthat close the housingand contain bearingsthat rotatably support a rotor. According to the present invention, spring elementsare provided that act upon at least one bearing shelleach of bearingswith a compression force acting in the axial direction, whereby the mounting of the bearing shellthat is acted upon by one of the spring elementsis configured as a sliding fit.
