Abstract[English]
A fluid-cooled, rotating electrical machine having a dry air gap. The rotating electrical machine includes a rotor assembly, a stator assembly, an annular air gap, and a fluid-tight barrier. The stator assembly is on a common center with the rotor assembly and has a stator core, stator coils passing through the stator core that have stator end-coils, and an ascending coolant channel extending axially through the stator core. The air gap is radially between the stator assembly and the rotor assembly. The fluid-tight barrier between the stator end-coils and the air gap.[French]
L'invention concerne une machine électrique tournante refroidie par fluide ayant un entrefer sec. La machine électrique tournante comprend un ensemble rotor, un ensemble stator, un entrefer annulaire et une barrière étanche aux fluides. L'ensemble stator est situé sur un centre commun avec l'ensemble rotor et comprend un noyau de stator, des bobines de stator traversant le noyau de stator et ayant des bobines d'extrémité de stator, et un canal de refroidissement ascendant s'étendant axialement à travers le noyau de stator. L'entrefer est radialement disposé entre l'ensemble stator et l'ensemble rotor. La barrière étanche aux fluides est située entre les bobines d'extrémité de stator et l'entrefer.
