DEMARREUR POUR MOTEUR THERMIQUE DE VEHICULE AUTOMOBILE MUNI D'UNE MACHINE ELECTRIQUE TOURNANTE A INDUCTEUR A POLES SAILLANTS PERFECTIONNE ET MASSE POLAIRE CORRESPONDANTE

摘要

A motor vehicle heat engine starter comprising a rotary electric machine (5) that has a rotor (9) and a stator (8) and comprises a plurality of magnetic poles (65) arranged on an internal circumference of a yoke (66). Each magnetic pole (65) is made up of a salient pole shoe (69) surrounded by a winding (70). The starter is characterized in that an air gap (76), separating the rotor (9) from the magnetic poles (65) of the stator (8), varies according to the circumference thereof. The invention also relates to a corresponding pole shoe (69).
