Title (EN) ROTOR FOR A ROTARY ELECTRIC MACHINE PROVIDED WITH AT LEAST ONE DEFORMABLE PORTION FOR FILLING A CAVITY
(FR) ROTOR DE MACHINE ELECTRIQUE TOURNANTE MUNI D'AU MOINS UNE PORTION DEFORMABLE POUR LE REMPLISSAGE D'UNE CAVITÉ
Abstract:
(EN) The invention mainly relates to a rotor (10) for a rotary electric machine, particularly for a motor vehicle, comprising: - a body (15) comprising a stack of laminations (16) stacked one on top of the other, - the stack of laminations (16) comprising: - a central opening (23) for the passage of a rotor shaft; - at least one cavity (26) intended to receive at least one permanent magnet (27), characterised in that the stack of laminations (16) further comprises: - a recess (30), and - a wall (31) separating the cavity (26) from the recess, - the wall (31) comprising at least one deformable portion (32) arranged to at least partially fill the recess (30) during deformation thereof.
(FR) L'invention porte principalement sur un rotor (10) de machine électrique tournante, notamment pour véhicule automobile, comportant: - un corps (15) 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, - au moins une cavité (26) destinée à recevoir au moins un aimant permanent (27), caractérisé en ce que le paquet de tôles (16) comporte en outre: - un évidement (30), et - une paroi (31) séparant la cavité (26) par rapport à l'évidement, - la paroi (31) comportant au moins une portion déformable (32) agencée pour remplir au moins partiellement l'évidement (30) lors de sa déformation.
