Abstract

Machine à refroidissement par liquide L’invention concerne une machine électrique tournante à refroidissement par liquide, comportant un rotor à aimants permanents et un stator bobiné, comportant : au moins un paquet (11) de tôles rotoriques, au moins un flasque (30) adjacent au paquet (11). La machine comporte un passage de circulation du liquide de refroidissement formé dans l’épaisseur du flasque, débouchant sur des sorties (34) disposées à sa périphérie. Chaque sortie est alimentée par au moins un canal d’alimentation respectif et présente une section offerte à l’écoulement du liquide qui est supérieure à celle d’au moins une portion dudit canal (35), située en amont. Figure pour l’abrégé : Fig. 3
