Abstract

L'invention porte sur une machine électrique tournante qui comporte un arbre (13) ; un rotor (12) monté sur l'arbre ; un stator (16) entourant le rotor, ledit stator comportant un corps (25) doté d'encoches et un bobinage (26) inséré dans les encoches, le bobinage comportant des chignons (27) s'étendant de part et d'autre du corps, les chignons comportant à leur base des ouvertures (30) s'étendant entre des conducteurs du bobinage sortant des encoches du corps ; un premier palier (37) et un deuxième palier (38) entourant un ensemble formé par le rotor et le stator et comportant chacun un logement (40, 44) pour le montage à rotation de l'arbre de rotor. Le premier palier comporte une zone de contact (Z1) sur le corps et au moins une ouïe (551, 552) située radialement au moins en partie en regard d'au moins une ouverture (30) d'un des chignons.
