Abstract

Une machine électrique rotative pour un véhicule, capable de réduire le plus possible l'influence d'un flux de fuite sur un détecteur d'angle de rotation et de détecter un angle de rotation de manière plus précise, est créée. Elle comprend : un noyau de rotor 12 fixé sur un arbre rotatif 7 ; un noyau de stator 24 concentrique au noyau du rotor 12 et disposé à l'extérieur du noyau du rotor 12 ; et un résolveur 31 agissant comme un détecteur d'angle de rotation disposé à une extrémité de l'arbre rotatif 7, dans lequel l'arbre rotatif 7 lui-même est réalisé de façon à être un moyen d'interruption du flux magnétique constitué d'un matériau non magnétique.
