Abstract

L'invention porte principalement sur un corps de stator (43) pour une machine électrique tournante, notamment pour véhicule automobile, comportant: - une culasse électrotechnique (51) permettant la circulation d'un flux magnétique, - des dents (52) issues d'une périphérie interne de la culasse électrotechnique (51) délimitant des encoches (54) destinées à recevoir des conducteurs d'un bobinage, caractérisé en ce que ladite culasse électrotechnique (51) présente une épaisseur radiale (L5) choisie au minimum nécessaire pour éviter une saturation magnétique de ladite culasse électrotechnique (51), - et en ce que ledit corps de stator (43) comporte en outre des crans (57) de support mécanique issus d'une périphérie externe de la culasse (51), un cran (57) de support mécanique s'étendant sur une plage angulaire (P) correspondant à au moins deux dents (52).The invention mainly relates to a stator body (43) for a rotating electrical machine, in particular for a motor vehicle, comprising: - an electrotechnical cylinder head (51) allowing the circulation of a magnetic flux, - teeth (52) coming from 'an internal periphery of the electrotechnical yoke (51) delimiting notches (54) intended to receive the conductors of a winding, characterized in that said electrotechnical yoke (51) has a radial thickness (L5) chosen to be the minimum necessary to avoid magnetic saturation of said electrotechnical yoke (51), - and in that said stator body (43) further comprises mechanical support notches (57) from an outer periphery of the cylinder head (51), a notch ( 57) of mechanical support extending over an angular range (P) corresponding to at least two teeth (52).
