A fly-by-wire (FBW) servo actuator may be used for primary flight control for an aircraft. The FBW servo actuator may have an inner output shaft coupled to an output arm that actuates a control surface of the aircraft. A first differential and a second differential may be coupled to the output shaft via a first outer shaft and a second outer shaft, respectively. Two inputs may be provided to each of the two differentials, and each input may be driven by a distinct motor. Thus, if one of the motors fails, the other motors may allow for uninterrupted operation of the servo actuator. The differentials may comprise harmonic gears driven by the two inputs. The inputs may be applied to a wave generator and a circular spline of the harmonic gear, and a flex spline of the harmonic gear may drive the outer shaft.
