Abstract

Изобретение относится к системам и способам охлаждения и смазки электрических машин с высокой удельной мощностью с усовершенствованной системой ввода текучей среды. Внутри электрической машины может быть предусмотрено множество проходов для потока текучей среды, которые могут включать канал для потока текучей среды к статору между статором и корпусом машины. Канал для потока текучей среды к статору может представлять собой один или более проходов, которые могут позволить текучей среде непосредственно контактировать со статором и ротором. Способ охлаждения электрической машины может включать направление текучей среды для протекания через один или более проходов между статором и корпусом, что дает возможность передавать тепло от статора и ротора к текучей среде, тем самым обеспечивая охлаждение статора и ротора.
