The invention relates to the technical field of aircraft front wheel control, and discloses an unmanned aerial vehicle all-electric front wheel turning control box, which comprises a main control assembly, a driving assembly, a power supply assembly and a power supply preprocessing assembly, and is characterized in that the main control assembly receives a turning instruction of a flight control machine and combines an actual position detected by a position sensor; a PWM signal is generated through processing of a position loop and current loop control algorithm and a three-phase brushless direct current motor six-step modulation algorithm, and the PWM signal is driven and amplified by a driving assembly to control the three-phase brushless direct current motor to move, so that a turning actuator is driven to drive a front wheel to turn; the power supply assembly converts an onboard power supply into various secondary power supplies required by the interior of the control box and a power supply required by an external clutch; and the power supply preprocessing assembly realizes signal crosslinking among the assemblies. The all-electric front wheel turning control box is not provided with a hydraulic pipeline, the problems of hydraulic oil leakage, pollution and the like do not exist, tedious oil way arrangement is not needed, and the installation space of a nose landing gear of an unmanned aerial vehicle is saved.
