Abstract

L'invention porte principalement sur un rotor (10) de machine électrique tournante, notamment pour véhicule automobile, comportant: - un corps (15) muni d'un axe (X) comportant un paquet de tôles (16) empilées les unes sur les autres, - le paquet de tôles (16) comportant: - une ouverture centrale (23) pour le passage d'un arbre de rotor (11), - au moins une cavité (26) destinée à recevoir au moins un aimant permanent (27), caractérisé en ce que la cavité (26) est délimitée par une face (263) munie d'au moins une languette déformable (28) s'étendant en saillie à l'intérieur de la cavité (26) et configurée pour exercer un effort sur l'aimant permanent (27) suivant une direction orthoradiale suite à sa déformation par l'aimant permanent (27).The invention relates mainly to a rotor (10) of a rotary electrical machine, in particular for a motor vehicle, comprising: - a body (15) provided with an axis (X) comprising a pack of sheets (16) stacked one on the other others, - the sheet pack (16) comprising: - a central opening (23) for the passage of a rotor shaft (11), - at least one cavity (26) intended to receive at least one permanent magnet (27 ), characterized in that the cavity (26) is delimited by a face (263) provided with at least one deformable tongue (28) projecting inside the cavity (26) and configured to exert a force on the permanent magnet (27) in an orthoradial direction following its deformation by the permanent magnet (27).
