The embodiment of the invention provides a power motor, an electric engine, an electric propulsion device and an aircraft, and relates to the technical field of aircrafts. The power motor comprises a stator, and the stator comprises a stator frame body and a stator winding. The stator frame body is provided with a liquid cooling cavity and a flow equalizing runner, and the stator winding is arranged in the liquid cooling cavity; the flow-equalizing flow channel is provided with a plurality of outlet ends which are arranged at intervals in the circumferential direction of the stator frame body, the outlet ends of the flow-equalizing flow channel are communicated with the liquid cooling cavity, and the flow-equalizing flow channel is used for enabling the flow of cooling liquid flowing into the liquid cooling cavity from the outlet ends of the flow-equalizing flow channel to be uniform. Therefore, the temperature of the power motor can be controlled within an allowable range, and the working performance of the power motor is ensured.

    本申请实施例提供一种动力电机、电动发动机、电推进装置及飞行器,涉及飞行器技术领域。动力电机包括定子,定子包括定子架体和定子绕组。定子架体上设置有液冷腔和均流流道,定子绕组设置在液冷腔的内部;均流流道具有沿定子架体的周向间隔排列的多个出口端,均流流道的多个出口端分别与液冷腔连通,均流流道用于使从均流流道的各个出口端流入液冷腔的冷却液的流量均匀。这样,可以将动力电机的温度控制在允许范围内,保证动力电机的工作性能。
