A miniaturized rotary electromechanical actuator relates to the field of spaceflight servo and comprises a permanent magnet synchronous motor, a gear reducer and an output rudder shaft, the permanent magnet synchronous motor is connected to the gear reducer, an output shaft of the permanent magnet synchronous motor extends into the gear reducer, the output rudder shaft is connected with a steering engine output main shaft, and the steering engine output main shaft is rotatably connected to the gear reducer. The gear reduction box comprises a box body and a reduction gear shaft system, the reduction gear shaft system comprises a first-stage spiral bevel gear and a plurality of straight gears which are rotationally connected to the box body, the axes of the first-stage spiral bevel gear and the multiple straight gears are parallel to the axis of the steering engine output main shaft, and the steering engine output main shaft is coaxially connected with a sixth-stage straight gear; an output shaft of the permanent magnet synchronous motor is coaxially connected with an output bevel gear, the first-stage spiral bevel gear comprises a bevel tooth part and a first pinion which are distributed in the axis direction of the first-stage spiral bevel gear and synchronously rotate, the bevel tooth part is meshed with the output bevel gear, and the first pinion is meshed with the sixth-stage straight gear through a plurality of straight gears. And the transmission efficiency of the rotary steering engine is improved.
