According to the unmanned aerial vehicle power system, the propeller rotates to drive external air to enter from the air inlet duct between the propeller hub fairing and the external fairing from top to bottom, and then the external air flows downwards through the internal flow air duct and the external flow air duct to dissipate heat of the motor. Wherein the bottom of the propeller hub fairing inclines outwards to guide airflow to flow along the inner wall of the outer fairing, and a bending part is arranged in the outer fairing, so that grit in the airflow tends to centrifugally flow towards the outer side, and the grit is further away from the inner flow air duct, does not enter the inner flow air duct and moves downwards along the outer flow air duct; and a first heat dissipation fan rotating along with the rotating shaft is arranged in the flow air duct, so that certain air can flow into the inner flow air duct from the outer flow air duct to dissipate heat of the motor. According to the unmanned aerial vehicle power system, the problem that in the prior art, the working state is affected due to the fact that the heat dissipation effect of a motor is poor is solved.

    本发明提供一种无人机动力系统,该无人机动力系统通过螺旋桨转动,带动外界空气从桨毂整流罩和外部整流罩之间的进气风道由上至下进入,再分别通过内流风道和外流风道向下流动对电机进行散热。其中,桨毂整流罩底部向外倾斜,引导气流沿着外部整流罩内壁流动,又外部整流罩内设有折弯部,使得气流内的沙砾,趋向离心朝外侧流动,进而使得沙砾离内流风道更远,进而不会进入内流风道内,并沿着外流风道向下移动,流风道内设有随转轴转动的第一散热风扇,以保证一定的空气从外流风道流入内流风道内对电机进行散热。本发明中的无人机动力系统,解决了现有技术中的电机散热效果差,从而影响工作状态的问题。
