Abstract

Machine électrique tournante Machine électrique tournante comportant : - un stator comportant des dents, des encoches entre les dents, des conducteurs électriques logés dans les encoches, lesquels forment un bobinage fractionnaire ou entier, et - un rotor comportant une masse rotorique et des aimants permanents insérés dans celle-ci, la masse rotorique étant composée d’une pluralité de paquets disposés consécutivement le long d’un axe de rotation du rotor, qui sont décalés angulairement autour de l’axe de rotation du rotor d’un angle élémentaire δ, avec δ compris dans l’un des deux intervalles suivant : bobinage fractionnaire : (360/(pn(he+2k)) ≤ δ ≤ (360/(pn(he-2k)) ou bobinage entier : (360/(pn(he+[2k+1]))) ≤ δ ≤ (360/(pn(he-[2k+1])) avec p le nombre de paires de pôles du rotor, n le nombre de paquets consécutifs décalés dans un même sens autour de l’axe de rotation, he = Ns/p, avec Ns le nombre d’encoches, et k égal à 0, 1 ou 2. Figure pour l’abrégé : Fig. 3
