The invention provides a power motor, an electric engine, an electric propulsion device and an aircraft, and relates to the technical field of aircrafts. A stator core assembly and a stator winding assembly of the power motor are arranged in the liquid cooling cavity of the support assembly. The cavity wall of the liquid cooling cavity is provided with a liquid outlet and at least two liquid supply ports. The at least two liquid supply ports are arranged at intervals in the axial direction of the stator iron core assembly. The liquid supply port is used for allowing a cooling medium to flow into the liquid cooling cavity, and the liquid outlet is used for allowing the cooling medium in the liquid cooling cavity to flow out. In this way, a cooling medium output by the liquid inlet flow channel can be output in the axial direction of the stator winding assembly through the at least two liquid supply ports and enters the liquid cooling cavity, the temperature of the liquid cooling cavity in the axial direction of the stator winding assembly can be more uniform, uniform heat dissipation of the coil winding and the stator winding assembly in the axial direction of the stator iron core assembly is achieved, and the cooling efficiency is improved. Therefore, the working performance of the power motor is improved.

    本申请提供一种动力电机、电动发动机、电推进装置及飞行器,涉及飞行器技术领域。动力电机的定子铁芯组件和定子绕组组件设置在支架组件的液冷腔内。液冷腔的腔壁具有出液口以及至少两个供液口。在定子铁芯组件的轴向上,至少两个供液口间隔排布。供液口用于供冷却介质流入液冷腔,出液口用于供液冷腔内的冷却介质流出。这样进液流道输出的冷却介质可以经由至少两个供液口沿定子绕组组件的轴向输出,进入液冷腔内,能够使得液冷腔在定子绕组组件的轴向的温度更加均匀,实现线圈绕组及定子绕组组件在定子铁芯组件的轴向上的均匀散热,以此来提高动力电机的工作性能。
