The invention, which belongs to the technical field of aviation, discloses a dual-redundancy electric steering engine. The dual-redundancy electric steering engine comprises a differential mechanism used for synthesizing two paths of input motions into a predetermined single rotary motion and outputting the predetermined single rotary motion to the outside, a first driving system and a second driving system, wherein the first driving system and the second driving system are used for respectively and independently inputting power in a rotary motion form to the differential mechanism, respectively and independently acquiring working state information of the steering engines, respectively and independently communicating with an upper computer, and mutually monitoring the working state througha bus. The invention provides a dual-redundancy electric steering engine scheme which is high in reliability and small in size.

    本发明公开了一种双余度电动舵机,属于航空技术领域。该双余度电动舵机包括:差速器,用于两路输入运动合成为预定的单一旋转运动对外输出;第一驱动系统和第二驱动系统,用于分别独立向所述差速器输入旋转运动形式的动力,分别独立采集舵机的工作状态信息,分别独立与上位机进行通信,并通过总线相互监听工作状态。本发明提供了一种可靠性高、体积较小的双余度电动舵机方案。
