Abstract

L'invention concerne une machine électrique synchrone à courant alternatif à aimant permanent, comprenant un stator (1) et un rotor (2). Un entrefer (7) est ménagé entre la circonférence extérieure du rotor (2) et la paroi intérieure du stator (1). La longueur minimale d'entrefer de l'entrefer (7) est notée gmin, et un angle de rotation mécanique d'une position avec la longueur minimale d'entrefer est nul. Le nombre de paires de pôles de la machine électrique est noté p. Une longueur d'entrefer d'une position avec un degré électrique de p·? est notée g(p·?). g(p·?) d'une position dans une plage de degrés électriques est inversement proportionnelle à une fonction cosinus du degré électrique.
