The invention discloses an electromagnetic positive and negative propeller power device of an electric fixed-wing aircraft. The power device comprises an electromagnetic positive and negative propeller structure and a positive and negative propeller control circuit, and the electromagnetic positive and negative propeller structure comprises a variable pitch rod, a torque conversion mechanism, a hollow shaft brushless motor, a bidirectional self-holding electromagnet, a motor mounting seat and a bidirectional self-holding electromagnet mounting seat; a coupler is arranged between the variable pitch rod and the bidirectional self-holding electromagnet, a connecting double-thread screw is arranged between the electromagnet mounting seat and the motor mounting seat, the torque conversion mechanism, the hollow shaft brushless motor and the bidirectional self-holding electromagnet are coaxially arranged, and the torque conversion mechanism is arranged at the front end of a main shaft. By theadoption of the structure, under the condition that motor steering of electric fixed-wing aircrafts including electric unmanned aerial vehicles, electric aircrafts and electric aviation model aircrafts is not changed, reverse thrust deceleration, ground reversing and emergency takeoff stopping of the electric fixed-wing aircrafts can be achieved. The device is convenient to maintain and replace parts, low in cost, compact in structure, small in size, light in weight, high in reliability, easy to operate, remarkable in function, novel and practical.
