Abstract

L’invention concerne un corps de stator (1) pour machine électrique à flux axial comprenant : - une base (2) comportant des couches (10) de tôle métallique qui sont enroulées autour d’un axe longitudinal (A1), la base présentant une face d’extrémité (3) sensiblement orthogonale à l’axe longitudinal, - des dents (4) réparties et fixées sur la face d’extrémité de la base. Selon l’invention la base comprend plusieurs portions angulaires (11) réparties autour de l’axe longitudinal, chaque portion angulaire comprenant au moins une couche plane, ladite couche plane se rattachant à une couche d’une portion angulaire adjacente par une pliure située au niveau de la fixation d’une desdites dents à la base.
