Abstract

L’invention porte sur une machine électrique tournante (10), notamment pour véhicule automobile, comportant: - un stator (11), - un rotor (12) monté sur un arbre (13), et - au moins un palier (14, 15) comportant des moyens de guidage (17) pour guider en rotation l'arbre (13), ladite machine électrique tournante (10) comportant en outre un élément de conduction thermique (27) présentant un coefficient de conduction thermique supérieur à celui de l'air, ledit élément de conduction thermique (27) étant disposé entre un chignon (25) du bobinage (24) et le palier (14, 15) de façon à favoriser une évacuation de calories du bobinage (24) vers le palier (14, 15) de la machine électrique tournante (10). Figure pour abrégé : Figure 1The invention relates to a rotary electrical machine (10), in particular for a motor vehicle, comprising: - a stator (11), - a rotor (12) mounted on a shaft (13), and - at least one bearing (14, 15) comprising guide means (17) for guiding the shaft (13) in rotation, said rotary electrical machine (10) further comprising a thermal conduction element (27) having a thermal conduction coefficient greater than that of the 'air, said thermal conduction element (27) being disposed between a chignon (25) of the coil (24) and the bearing (14, 15) so as to promote evacuation of heat from the coil (24) to the bearing (14) , 15) of the rotating electric machine (10).
