Abstract

L’invention concerne un corps de stator pour machine électrique, comportant : - au moins un support de fixation (102A) centré sur un axe longitudinal, - des dents (120) qui sont adaptées à recevoir des bobines de fil électriquement conducteur et qui sont régulièrement réparties autour de l’axe longitudinal, et - des moyens de fixation adaptés chacun à fixer l’une desdites dents sur le support de fixation. Selon l’invention, chaque moyen de fixation comporte : - en saillie d’une face (109A) du support de fixation, une nervure (112A), - en creux dans une face correspondante (129) de la dent, une rainure principale (124) qui débouche sur ladite face correspondante par un orifice de largeur supérieure à la largeur de la nervure et qui présente deux faces latérales, et - au moins une clavette engagée dans la rainure principale de manière à s’appuyer sur une face latérale de la rainure principale et à repousser la nervure contre l’autre face latérale de la rainure principale. Figure pour l’abrégé : Fig.2The invention relates to a stator body for an electrical machine, comprising: - at least one fixing support (102A) centered on a longitudinal axis, - teeth (120) which are adapted to receive spools of electrically conductive wire and which are regularly distributed around the longitudinal axis, and - fixing means each adapted to fix one of said teeth on the fixing support. According to the invention, each fixing means comprises: - projecting from one face (109A) of the fixing support, a rib (112A), - recessed in a corresponding face (129) of the tooth, a main groove ( 124) which opens onto said corresponding face through an orifice of width greater than the width of the rib and which has two lateral faces, and - at least one key engaged in the main groove so as to rest on a lateral face of the main groove and to push the rib against the other side face of the main groove.
