The invention relates to the technical field of brushless direct-current motor high-efficiency platform extension intelligent control devices, in particular to a dual-motor efficient intelligent FOC drive system. The dual-motor efficient intelligent FOC drive system comprises a power source, a power supply circuit, a speed regulation handle, a double-stator drive motor and an FOC control circuit for controlling a double-stator drive device, the double-stator drive motor comprises a shell, a main motor set in the shell, an auxiliary motor set and a stator shaft, and the FOC control circuit comprises a speed control circuit electrically connected with the main motor set and a torque control circuit electrically connected with the auxiliary motor set. The main motor set comprises a total stator, magnetic steel and a main rotor arranged on the stator shaft in a sleeving mode. The auxiliary motor set comprises a total stator, magnetic steel and an auxiliary rotor arranged on the stator shaft in a sleeving mode. According to the dual-motor efficient intelligent FOC drive system, the main motor set and the auxiliary motor set cannot be disturbed by magnetic line cutting, the work efficiency of the motor is greatly improved, and work cost is lowered.
