Device, in particular for an electrical machine, for attaching a magnetical ring to a part, preferably a magnetical back yoke

摘要

there is an arrangement, in particular to an electric machine (10) for fixing at least one magnetringes (18) on a circuit board (20), preferably a magnetic identification, is proposed.the component (20) has an axial and radial extension (a, r), and a volume (24), in which the at least one magnetring (18) preferably by means of a thin and elastic kleberschicht is fixed and by means of at least one federelements (30) the different wu00e4rmeaus elongation of the different materials used, is compensated.erfindungsgemu00e4u00df is provided that at least one federelement (30), at least one in axial extension of (a) providing, from the scale (24) of the component (20) based hinterschneidung whose cross-sectional area is at least partially transverse to the radial extension (s) of the built ils (20) passes.the at least one hinterschneidung is a anlageabschnitt (32) on the scale (24) of the component (20) undercuts, springy, and where the at least one magnetring (18) according to the wu00e4rmeausdehnung, at least in part on it.
