The invention provides an electric front wheel control device suitable for an all-electric unmanned aerial vehicle undercarriage, and belongs to the technical field of all-electric aircraft undercarriage control. The device comprises a dual-redundancy servo motor used for providing power, a first planetary speed reducing mechanism connected with the dual-redundancy servo motor, an electromagnetic clutch connected with the first planetary speed reducing mechanism, a straight tooth speed reducing mechanism connected with the electromagnetic clutch, an eddy current damper connected with the straight tooth speed reducing mechanism at the same time, and a second planetary speed reducing mechanism. According to the control device, through the integrated design of the turning function and the shimmy damping function, compared with a hydraulic mechanical control device, the size is reduced by 30%, the weight is reduced by 35%, and the control device is compact in structure, small in size, light in weight, convenient to control, fast in shimmy damping response, low in cost, good in damping effect and suitable for popularization and application. The system has the advantages in the aspects of maintainability, environmental protection, service life, structural principle and the like, and can meet the shimmy damping requirement of the all-electric unmanned aerial vehicle.
