Abstract

Вращающаяся электрическая машина содержит статор (1) с обмоткой из высоковольтного кабеля, имеющий зубцы (4) статора, идущие радиально внутрь от внешней части ярма (5), причем, по меньшей мере, один зубец статора (4) соединен, по меньшей мере, с одной охлаждающей трубкой (18), идущей радиально в зубце статора (4) и соединенной с контуром (34) охлаждения, в котором циркулирует хладагент (36), причем охлаждение осуществляется, по меньшей мере, вдоль большей части зубца (4) статора в осевом направлении. Описан также способ охлаждения вращающейся электрической машины с высоковольтными статорными обмотками, при котором статор охлаждают хладагентом (36), который циркулирует в контуре (34) охлаждения через каналы охлаждения, идущие через зубцы статора (4) в радиальном направлении.Международная заявка была опубликована вместе с отчетом о международном поиске.
