Abstract

Изобретение относится к электрическим машинам и способам их охлаждения. Предложенная электрическая машина содержит ротор, закрепленный на вращающемся валу и поддерживаемый с помощью одного или более подшипников, статор, неподвижный по отношению к вращающемуся ротору и валу, с зазором между ротором и статором, корпус, окружающий всю машину или ее часть, и множество проходов для потока текучей среды внутри машины. Электрическая машина может содержать проходы для потока текучей среды, которые могут включать один или более каналов для потока текучей среды к статору между статором и корпусом, один или более каналов для потока текучей среды к ротору вдоль вращающегося вала в направлении к ротору и статору и один или более каналов для потока текучей среды к подшипнику, контактирующих по меньшей мере с одним подшипником. Электрическая машина может содержать один или более каналов для потока текучей среды к статору между статором и корпусом, причем указанный канал может включать один или более проходов для потока текучей среды, что позволяет текучей среде непосредственно контактировать с внешней поверхностью статора. Способ охлаждения электрической машины может включать пропускание текучей среды в одном или более проходах между статором и корпусом, так что текучая среда непосредственно контактирует со статором и позволяет теплу переходить от статора к текучей среде, тем самым охлаждая статор.
