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 fan and a radiator. The power motor is provided with a liquid cooling flow channel, and the liquid cooling flow channel and the radiator are used for forming a cooling medium circulation loop. The fan is provided with an air inlet side and an air outlet side in the axial direction of the fan, the power motor is located on the air inlet side of the fan, and the radiator is located on the air outlet side of the fan. The fan is provided with an air guide assembly, and the air guide assembly is used for guiding part of airflow on the air inlet side of the fan to the middle area of the fan and blowing the airflow to the radiator from the middle area of the fan. Therefore, the heat dissipation efficiency of the power motor is high, and the working performance of the power motor can be guaranteed.
