Abstract

Il s'agit d'un rotor (1) à aimants permanents comportant un paquet de tôles avec des logements (9) dont certains reçoivent au moins un élément sous la forme d'un aimant (14) permanent. Le rotor (1) comporte en outre des dispositifs de maintien (17) comportant chacun : - une partie centrale (19) s'étendant axialement à l'intérieur d'un logement (9) entre une face axiale (91,91 a,91 b) du logement (9) et une face (15) d'un aimant (14), cette partie centrale (19) ayant une forme telle qu'elle exerce par déformation un effort radial sur l'aimant (14) et sur la face axiale (91, 91a, 91b), - des premier (30) et second (40) moyens de retenue portés par ladite partie centrale (19) à chacune de ses extrémités (20) et faisant saillie par rapport au logement (9) suivant l'axe (X), chacun desdits premier et second moyens de retenue (30,40) ayant des formes telles qu'ils exercent par déformation, un effort axial sur des faces respectivement inférieure (4) et supérieure (5) dudit corps (3).It is a rotor (1) with permanent magnets comprising a pack of sheets with housings (9) some of which receive at least one element in the form of a permanent magnet (14). The rotor (1) further comprises holding devices (17) each comprising: - a central portion (19) extending axially inside a housing (9) between an axial face (91, 91 a, 91 b) of the housing (9) and a face (15) of a magnet (14), this central portion (19) having a shape such that it deforms a radial force on the magnet (14) and on the axial face (91, 91a, 91b), - first (30) and second (40) retaining means carried by said central portion (19) at each of its ends (20) and protruding relative to the housing (9). ) along the axis (X), each of said first and second retaining means (30, 40) being shaped such that they exert, by deformation, an axial force on respectively lower (4) and upper (5) faces of said body (3).
