The embodiment of the invention provides an electric engine, an electric propulsion device and an aircraft, and relates to the technical field of aircrafts. The electric engine comprises a power motor, a radiator, a driving motor and a fan. And the radiator is used for radiating the power motor. The driving motor and the power motor are located on the two sides of the radiator respectively in the axial direction of the power motor, the driving motor is provided with a containing through hole, and the radiator covers one side of the containing through hole. At least part of the fan is located in the containing through hole, and the fan is in transmission connection with the driving motor. In this way, the axial size of the electric propulsion device is shortened, and the resistance borne by the aircraft in the flying process is reduced.

    本申请实施例提供一种电动发动机、电推进装置及飞行器,涉及飞行器技术领域。电动发动机包括动力电机、散热器、驱动电机和风扇。散热器用于对动力电机进行散热。沿动力电机的轴向驱动电机和动力电机分别位于散热器的两侧,驱动电机设有容纳通孔,散热器覆盖容纳通孔的一侧。风扇的至少部分位于容纳通孔的内部,风扇与驱动电机传动连接。这样,缩短电推进装置的轴向尺寸,降低飞行器在飞行过程中受到的阻力。
