Title (EN) ROTARY ELECTRIC MACHINE WITH SIMPLIFIED RETENTION OF THE ELECTRONIC ASSEMBLY
(FR) MACHINE ELECTRIQUE TOURNANTE AVEC UN MAINTIEN DE L'ENSEMBLE ELECTRONIQUE SIMPLIFIE
Abstract:
(EN) The present invention proposes a rotary electric machine, notably for a motor vehicle, comprising: – a rotor (12) and a stator (15) extending along an axis (X); – a casing (11) surrounding the rotor and the stator and comprising at least one end plate (17); and – an electronic assembly (36) comprising a heat sink (37) and at least one power electronics module mounted on said heat sink, the heat sink being mounted on the end plate. The machine (10) further comprises at least one pressing device (43) projecting between the heat sink (37) and the end plate (17), said device being mounted between said elements with preload.
(FR) La présente invention propose une machine électrique tournante, notamment pour véhicule automobile, comportant: - un rotor (12) et un stator (15) s'étendant suivant un axe (X); - un carter (11) entourant le rotor et le stator et comportant au moins un flasque (17); et - un ensemble électronique (36) comportant un dissipateur thermique (37) et au moins un module électronique de puissance monté sur ledit dissipateur, le dissipateur étant monté sur le flasque. La machine (10) comporte, en outre, au moins un dispositif d'appui (43) s'étendant en saillie entre le dissipateur thermique (37) et le flasque (17), ledit dispositif étant monté entre lesdits éléments avec une précontrainte.
