Abstract

L'invention porte principalement sur une machine électrique tournante pour véhicule automobile. La machine (10) comporte un arbre (13) ; un rotor (12) ; un stator (16) comportant un corps (25) doté d'encoches et un bobinage (26) inséré dans les encoches ; 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 (13). Le premier palier comporte un flasque (371) transversal et une paroi cylindrique (372) d'orientation axiale issue d'une périphérie externe dudit flasque. Le deuxième palier comporte un flasque (48) transversal fermant le premier palier et au moins un rebord (63) s'étendant en saillie à partir du flasque et formant une zone de jonction (64) avec le premier palier. En outre, le corps de stator comporte une zone de frettage (Z1) avec la paroi cylindrique.The invention relates mainly to a rotary electric machine for a motor vehicle. The machine (10) comprises a shaft (13); a rotor (12); a stator (16) having a body (25) provided with notches and a coil (26) inserted in the notches; a first bearing (37) and a second bearing (38) surrounding an assembly formed by the rotor and the stator and each comprising a housing (40, 44) for the rotational mounting of the rotor shaft (13). The first bearing comprises a transverse flange (371) and a cylindrical wall (372) of axial orientation issuing from an outer periphery of said flange. The second bearing comprises a transverse flange (48) closing the first bearing and at least one flange (63) projecting from the flange and forming a junction zone (64) with the first bearing. In addition, the stator body has a hooping zone (Z1) with the cylindrical wall.
