The invention relates to the technical field of wireless charging, in particular to a low-leakage magnetic flux interference omnibearing energy transfer unmanned aerial vehicle wireless charging system which comprises a transmitting module arranged on a wireless charging platform and a receiving module arranged on an unmanned aerial vehicle. The transmitting module is composed of an A-phase solenoid transmitting coil, a B-phase solenoid transmitting coil and a C-phase solenoid transmitting coil, each phase solenoid transmitting coil comprises two arc-shaped solenoid coils, and the three phases of solenoid transmitting coils are uniformly distributed on the same plane to form a complete circumference; the receiving mechanism comprises two receiving coils, and the two receiving coils are wound on two supporting legs of an undercarriage of the unmanned aerial vehicle respectively; the transmitting module mainly generates a magnetic field in the horizontal direction, almost does not generate a magnetic field in the vertical direction, and reduces leakage magnetic flux interference. Current with 120-degree phase difference is excited in a three-phase solenoid transmitting coil to generate a rotating magnetic field, and all-directional wireless energy transmission at any position and at any angle deviation is realized.
