The invention belongs to the technical field of motors, and discloses a differential dual-output motor. The differential dual-output motor comprises a motor shell body, a stator and a rotor, wherein the rotor is relatively fixed to the motor shell body, the rotor is arranged inside the stator in a rotated manner, an axis part of the rotor is of a cavity structure, a differential mechanism is arranged in a cavity body at the axis part of the rotor, and the differential mechanism comprises two coaxial planetary gears which are oppositely arranged and two coaxial half axle gears which are oppositely arranged; and a planetary gear shaft of the differential mechanism is relatively fixed to the rotor, and the two half axle gears of the differential mechanism are respectively connected with two output half shafts of the motor. The differential dual-output motor adopts the dual-half-shaft output and hollow rotor structure design, integrates the differential mechanism in the hollow cavity body of the rotor, achieves the dual-half-shaft differential output function, greatly reduces the occupied space of a power assembly, and has the advantages of high output efficiency, low energy loss, energy saving and environmental protection.
