Title (EN) ROTOR FOR A ROTARY ELECTRIC MACHINE INCLUDING AN OPEN CHAIN OF AT LEAST TWO INTERPOLAR MEMBERS DEFINING A MAGNETIC BARRIER
(FR) ROTOR DE MACHINE ELECTRIQUE TOURNANTE COMPORTANT UNE CHAINE OUVERTE D'AU MOINS DEUX ELEMENTS INTERPOLAIRES FORMANT BARRIERE MAGNETIQUE
Abstract: front page image
(EN)The invention relates to a rotor (24) for a rotary electric machine (20) mainly for the automotive industry, that comprises a front polar wheel (46N) and a rear polar wheel (46S), each polar wheel (46N, 46S) including claws (52) extending axially towards the other polar wheel (46S, 46N), each claw (52) of a polar wheel (46S, 46N) being circumferentially interleaved between two claws (52) of the other polar wheel (46S, 46N), at least two interpolar gaps (62) being provided between the side faces (60) opposite two successive claws (52), and at least two members (68) defining a magnetic barrier being provided in two interpolar gaps (62) associated on either side with a predetermined claw (52D), characterised in that the front longitudinal ends (72) of said two members (68) are connected by a connector (82) essentially in order to define an open chain (80).
(FR)L'invention concerne un rotor (24) de machine électrique tournante (20), notamment pour véhicule automobile, qui comporte une roue polaire avant (46N) et une roue polaire arrière (46S), chaque roue polaire (46N, 46S) comportant des griffes (52) qui s'étendent axialement en direction de l'autre roue polaire (46N, 46S), chaque griffe (52) d'une roue polaire (46N, 46S) étant imbriquée circonférentiellement entre deux griffes (52) de l'autre roue polaire (46N, 46S), au moins deux espaces interpolaires (62) étant réservés entre les faces latérales (60) en vis-à-vis de deux griffes (52) consécutives, et au moins deux éléments (68) formant barrière magnétique étant agencés dans deux espaces interpolaires (62) associés de part et d'autre d'une griffe déterminée (52D), caractérisé en ce que les extrémités longitudinales (72) avant desdits deux éléments (68) sont reliés par une attache (82) notamment de manière à former une chaîne ouverte (80).
