Abstract

La présente invention propose une machine électrique tournante, notamment pour véhicule automobile, comportant: un rotor (12) et un stator (15) formant des parties actives s'étendant suivant un axe (X), un carter (11) entourant les parties actives et comportant au moins deux flasques (16, 17), et un ensemble électronique (24) monté sur le carter (11) et comportant au moins un module de puissance (22) monté sur un dissipateur thermique (23). La machine (10) comporte, en outre, un circuit de refroidissement (37) permettant le passage d'un liquide, le circuit de refroidissement comportant une première chambre de refroidissement (39) formée dans le dissipateur thermique (23) et une seconde chambre de refroidissement (40) formée dans le carter (11).The present invention provides a rotary electrical machine, in particular for a motor vehicle, comprising: a rotor (12) and a stator (15) forming active parts extending along an axis (X), a casing (11) surrounding the active parts and comprising at least two flanges (16, 17), and an electronic assembly (24) mounted on the casing (11) and comprising at least one power module (22) mounted on a heat sink (23). The machine (10) further comprises a cooling circuit (37) allowing the passage of a liquid, the cooling circuit comprising a first cooling chamber (39) formed in the heat sink (23) and a second chamber cooling (40) formed in the housing (11).
