Abstract

Un rotor (100) à aimants permanents pour moteur électrique comprend une cloche (110) comportant une paroi annulaire (112) et au moins un aimant permanent (120) fixé sur la paroi annulaire par l'intermédiaire de moyens adhésifs (126) disposés entre la paroi annulaire (112) et une face arrière (124) de l'aimant permanent (120). La face arrière (124) de l'aimant permanent (120) présente une zone de contact (134) centrale définie par un rayon de courbure (R1) identique au rayon de courbure (R) de la paroi annulaire (112), ladite face arrière étant conformée de manière à créer au moins une portion de dégagement (136) s'étendant latéralement à ladite zone de contact (134) centrale pour former au moins une cavité de réception desdits moyens adhésifs (126).A rotor (100) with permanent magnets for an electric motor comprises a bell (110) having an annular wall (112) and at least one permanent magnet (120) fixed to the annular wall by means of adhesive means (126) disposed between the annular wall (112) and a rear face (124) of the permanent magnet (120). The rear face (124) of the permanent magnet (120) has a central contact zone (134) defined by a radius of curvature (R1) identical to the radius of curvature (R) of the annular wall (112), said face rear being shaped so as to create at least one clearance portion (136) extending laterally from said central contact zone (134) to form at least one cavity for receiving said adhesive means (126).
