多轴、多层电机的冷却结构
摘要：
一个多轴、多层电机包括一个内转子、一个包围着内转子的外转子、以及一个同轴地设在内、外转子之间的定子。电机还包括一个包围外转子并在外转子和外构件之间确定了第一湿室的外构件；一个确定了被内转子包围的第二湿室的内构件；以及一个确定了干室的中间构件，干室与定子和外转子之间的外空气间隙以及与定子和内转子之间的内空气间隙连通。
摘要（英）：

A multi-shaft, multi-layer motor includes an inner rotor, an outer rotor surrounding the inner rotor, and a stator disposed coaxially between the inner and outer rotors. The motor further includes anouter member surrounding the outer rotor and defining a first wet chamber between the outer rotor and the outer member; an inner member defining a second wet chamber surrounded by the inner rotor; andan intermediate member defining a dry chamber communicating with an outer air gap between the stator and the outer rotor, and an inner air gap between the stator and the inner rotor.
