An electromagnetic ejection device for an unmanned aerial vehicle comprises a chassis, a frame body, a rotor, a stator, a pulley and an electric push rod. The bottom of the frame body is connected with the upper surface of the chassis through a rotating support lug, one end of the electric push rod is connected with the middle of the frame body, and the other end of the electric push rod is mounted on the upper surface of the chassis; and the frame body can perform tilting on the chassis through action of the electric push rod; the stator comprises a plurality of windings which are uniformly distributed on the two sides of the frame body in a linear shape, a guide rail is arranged on the frame body, the rotor is installed on the guide rail, a permanent magnet is installed on the rotor, and the rotor can reciprocate along the guide rail along with the change of a magnetic field; the lower end of the pulley is fixedly connected with the rotor. The unmanned aerial vehicle is arranged at the upper end of the pulley. The electromagnetic ejection device has the advantages of being simple in structure, compact and reliable, meanwhile, the failure rate of all parts is low, the interchangeability of all the parts is high, and maintenance is convenient; in addition, as an ejection device of the unmanned aerial vehicle, the electromagnetic ejection device is small in launching load, low in cost, convenient to store and transport, good in rapidity and high in control efficiency and control accuracy.
