The invention relates to a small-sized electric steering engine with an adjustable reduction ratio. Comprising a driving assembly, an output assembly and a transmission assembly. The driving assembly comprises a sleeve, a motor connected to one side of the sleeve and a ball screw pair arranged in the sleeve, an output shaft of the motor is coaxially connected with a lead screw of the ball screw pair, at least one sliding rail is fixedly arranged on one side of the sleeve, and at least one strip-shaped limiting hole is formed in the wall of the sleeve; the output assembly comprises a mounting base, a torque output shaft and a plurality of bearings, the interior of the mounting base is of a stepped hollow structure, the torque output shaft is mounted in the mounting base, and the bearings are arranged between the torque output shaft and the mounting base; one end of the transmission assembly is movably connected to the cylindrical pin, the other end of the transmission assembly penetrates through the installation base to be fixedly connected to the torque output shaft, and the transmission assembly can stretch out and draw back in the length direction. The steering engine has the advantages of being simple in structure, low in cost, convenient to install, adjustable in reduction ratio and capable of being well applied to small and medium-sized aircrafts.
