Abstract

L’invention porte sur un carter (28) pour machine électrique tournante (1) ayant un axe de rotation (A), le carter (28) comprenant : - un corps (7) comprenant une surface radialement intérieure (42) apte à porter un stator (10) de machine électrique tournante (1) et comprenant :    - une poche (11) formant une chambre de refroidissement (23) apte à recevoir un fluide de refroidissement, la poche (11) s’étendant sur tout ou partie du pourtour de l’axe de rotation (A),    - une enveloppe (14) au moins partiellement surmoulée sur la poche (11), - une première paroi latérale (6) apte à supporter en rotation un arbre (4) de rotor, notamment par l’intermédiaire d’un premier roulement (18), et située à une extrémité axiale du carter (28). L’invention porte également sur une machine électrique tournante comprenant un tel carter. Figure pour l’abrégé : Figure 1The invention relates to a casing (28) for a rotating electrical machine (1) having an axis of rotation (A), the casing (28) comprising: - a body (7) comprising a radially interior surface (42) capable of supporting a stator (10) of a rotating electrical machine (1) and comprising: - a pocket (11) forming a cooling chamber (23) capable of receiving a cooling fluid, the pocket (11) extending over all or part of the periphery of the axis of rotation (A), - an envelope (14) at least partially overmolded on the pocket (11), - a first side wall (6) capable of supporting in rotation a rotor shaft (4), in particular via a first bearing (18), and located at an axial end of the housing (28). The invention also relates to a rotating electric machine comprising such a casing. Figure for abstract: Figure 1
