The invention discloses a two-channel electric steering engine. The two-channel electric steering engine comprises a control board, a driving board and a connector which are fixedly arranged on a steering engine shell, and two transmission mechanisms, the two transmission mechanisms share a body and are arranged in a mirror image manner, the two transmission mechanisms independently realize moment output, and an included angle between the output shafts of the two transmission mechanisms is 90-180DEG; and when the two-channel electric steering engine works and the motor rotates, gear decelerates to drive leading screws to rotate, and a ball screw assembly becomes linear motion from rotary motion, and pushes a rocking arm to rotate through a link mechanism in order to realize moment and speed output. A feedback element sensitively outputs the positions and models of the shafts, and the control board and the driving board control the motor to rotate in order to realize a positional closed loop. An integrated design idea is adopted in the embodiment of the invention, and the so the two transmission mechanisms, the driving board and the control board are designed in an integral manner, so the two-channel electric steering engine has the characteristics of small size, light weight, high integration degree and good dynamic performance.
