Abstract

L'invention concerne une machine électrique tournante (10) de véhicule automobile comportant un rotor (105), un boîtier (110) délimitant au moins en partie une enceinte (125) à l'intérieur de laquelle le rotor (105) est monté rotatif autour d'un axe (X), la machine électrique tournante (10) étant caractérisée en ce qu'elle comporte un unique ventilateur (130), solidaire en rotation au rotor (105) et en ce que le boîtier (110) comporte deux paliers (135, 150) d'aération : - un premier palier comportant au moins une ouverture (140, 145) d'entrée d'air et - un deuxième palier comportant au moins une ouverture radiale (160) de sortie d'air, de sorte que le ventilateur (130) provoque une circulation forcée d'air de refroidissement dans l'enceinte (125).The invention relates to a rotating electrical machine (10) for a motor vehicle comprising a rotor (105), a casing (110) defining at least in part an enclosure (125) inside which the rotor (105) is rotatably mounted around an axis (X), the rotating electric machine (10) being characterized in that it comprises a single fan (130), fixed in rotation to the rotor (105) and in that the casing (110) comprises two ventilation bearings (135, 150): - a first bearing comprising at least one air inlet opening (140, 145) and - a second bearing comprising at least one radial air outlet opening (160), so that the fan (130) causes a forced circulation of cooling air in the enclosure (125).
