An electromagnetic driven micro ornithopter comprises a body, a piston cylinder, an AC power supply, upper and lower electromagnetic coils, a permanent magnet, left and wing motion bars, left wing and right wing rotation shafts, left wing and right wing frameworks and left wing and right wing fins, wherein the piston cylinder and the AC power supply are internally arranged in the frame of the body; the upper and lower electromagnetic coils are arranged at the upper and lower ends of the piston cylinder respectively; the AC power supply is connected with the upper and lower electromagnetic coils; a permanent magnet sleeve is positioned in the middle part of the piston cylinder; the permanent magnet is internally arranged in the permanent magnet sleeve; one end of the left motion pole and one end of the right motion pole are fixed to the left side and the right side of the permanent magnet sleeve and the other end of the left motion pole and the other end of the right motion pole are fixedly to the left wing rotation shaft and the right wing rotation shaft; the left wing rotation shaft and the right wing rotation shaft are fixed to the ends of the left wing framework and the right wing framework; and the right ends of the left wing fins and the left ends of the right wing fins are fixed to the left wing framework and the right wing framework respectively. According to the invention, the upper and lower electromagnetic coils are used for providing magnetic force, so that the flapping power output is doubled. The defect that the magnetic force of a single coil may be influenced by the travel distance is made up and the power output becomes more stable.
