Abstract

A holding element (68, 82) for attaching magnets (62) to a rotor (20) of an electrical machine (10). This electrical machine is, in particular, designed as an AC generator and comprises intermediate spaces (60) between the individual poles (24, 25). The holding element (68, 82) comprises a top side (72) and spring lugs (70) which axially fix the magnets (62). The holding element (68, 82) has claw-like projections (74) which bear against flanks (80) of the poles (24, 25) when the holding element (68, 82) is in the fitted state.
