Abstract

L'invention concerne une machine électrique tournante, notamment un alternateur de véhicule automobile, comprenant une enveloppe extérieure (10), un stator, un rotor, et un ventilateur à pales (50) disposé d'un premier côté axial du rotor, l'enveloppe (10) présentant une ouïe d'entrée d'air et une ouïe de sortie d'air (71), les ouïes d'entrée et de sortie (71) étant constituées chacune d'une ouverture (80) subdivisée par des ailettes (90) chacune allongée suivant un profil qui lui est propre.Selon l'invention, au moins une ailette (90) de l'une au moins des ouïes d'entrée et/ou de sortie (71) est inclinée de telle sorte que des bords des pales (51) tournés vers ladite ouïe balayent progressivement l'ailette (90) suivant son profil en tournant autour de l'arbre rotatif, suivant un mouvement de cisaillement selon lequel à chaque instant seule une portion sensiblement ponctuelle du bord de la pale (51) est en vis-à-vis de l'ailette (90).
