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 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

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.
