The invention discloses an unmanned aerial vehicle empennage electric propulsion conical permanent magnet synchronous motor and a design method, and belongs to the related field of aviation electric propulsion system motor design. The design method comprises the steps that the axial force of the propeller at the set rotating speed is determined according to the relation between the axial force of the propeller and the rotating speed; the torque of the propeller at the set rotating speed is determined; the propeller torque is matched with the electromagnetic torque of a motor, so that the electromagnetic torque can drive the propeller to work normally; matching the axial force of the propeller with the axial magnetic pulling force of the motor to obtain the lower limit of the taper angle of the motor; the size range of the motor structure is obtained by combining the rotating speed and the torque of the propeller; and optimizing the structure of the motor to obtain a determined taper angle of the motor. The problems that when the bearing runs, the bearing is subjected to large axial force of the propeller for a long time, so that the bearing of the electric propulsion motor is abraded, and potential safety hazards are generated are solved.
