Abstract

L'invention porte principalement sur une machine électrique tournante comportant un rotor (11) et un stator caractérisée en ce que ledit rotor (11) comprend: - un corps de rotor (27) en matière ferromagnétique comportant un paquet de tôles, et - des pôles magnétiques définis chacun par des aimants permanents (30) disposés à l'intérieur de deux uniques logements (28) par pôle magnétique présentant une forme en V, - et en ce qu'un secteur angulaire (S) s'étendant entre deux axes (X3) de deux pôles magnétiques adjacents comporte: - deux premières zones (A) de retrait de matière ferromagnétique s'étendant chacune entre un axe (X3) d'un pôle magnétique et un logement (28) d'un aimant permanent (30) adjacent, - une deuxième zone (B) de retrait de matière ferromagnétique, et - une troisième zone (C) de retrait de matière ferromagnétique disposée entre une périphérie interne du rotor (11) et la droite (K) de séparation de zone.
