Abstract

Stator (1) de machine électrique tournante, comportant une masse statorique (2) formée d'un empilement de tôles, les tôles comportant des dents (4) ménageant entre elles des encoches (3) qui sont symétriques par rapport à un axe radial de l'encoche, et des conducteurs électriques logés dans les encoches (3), au moins l'une des tôles de la masse statorique (2) comportant une pluralité de crans (10) ménagés dans les dents (4), à leur extrémité faisant face à l'entrefer (E), la masse statorique étant composée d'une pluralité de paquets (2a, 2b) de tôles disposés consécutivement le long d'un axe longitudinal X du stator, les crans (10) des tôles d'un premier paquet (2a) étant décalée angulairement par rapport aux crans des tôles d'un deuxième paquet (2b).
