Abstract

L'invention porte principalement sur une machine électrique tournante pour véhicule automobile comportant: - un stator comportant un corps et un bobinage (18) muni de chignons (20) s'étendant de part et d'autre du corps de stator, - au moins un palier (35) comportant un plateau (53) et une jupe (54), - le palier (35) comportant une face interne (62) tournée vers un chignon de bobinage (20) et des ouvertures latérales pour le passage d'air de refroidissement, caractérisée en ce que la face interne (62) comporte une portion périphérique inclinée (64) par rapport à un plan (P1) orthogonal à un axe (X) suivant lequel s'étend le stator de manière à augmenter un espace (67) pour le passage d'air de refroidissement entre le chignon de bobinage (20) et le palier (35).The invention relates mainly to a rotary electrical machine for a motor vehicle comprising: - a stator comprising a body and a winding (18) provided with chignons (20) extending on either side of the stator body, - at least a bearing (35) comprising a plate (53) and a skirt (54), - the bearing (35) comprising an internal face (62) facing a winding chignon (20) and lateral openings for the passage of air cooling, characterized in that the internal face (62) comprises an inclined peripheral portion (64) with respect to a plane (P1) orthogonal to an axis (X) along which the stator extends so as to increase a space ( 67) for the passage of cooling air between the winding chignon (20) and the bearing (35).
