Abstract

L’invention concerne une machine électrique tournante (10) comprenant : un rotor (12) mobile en rotation autour d’un axe (X),un stator (11) disposé autour du rotor (12), etune chambre (31) de refroidissement disposée radialement autour du stator (12), délimitée entre une paroi radialement intérieure (70) et une paroi radialement extérieure (71), un fluide de refroidissement circulant dans cette chambre (31) entre une entrée (41) et une sortie (42) en fluide dans la chambre, un circuit d’entrée de fluide (51) communiquant avec l’entrée (41) et un circuit de sortie de fluide (52) communiquant avec la sortie (42), dans laquelle le circuit d’entrée en fluide (51) comprend une portion d’étranglement (55) entre une section (56) de grand diamètre (D2) et une section (57) de petit diamètre (D1) et en ce qu’un ratio (R) entre le petit et le grand diamètre (D1/D2) est compris entre 0,4 et 0,9. Figure pour l’abrégé : Fig. 3
