The invention relates to the technical field of motors, and discloses a double-stator fault-tolerant motor which comprises a machine shell, an outer stator, a rotor and an inner stator, the outer stator, the rotor and the inner stator are sequentially and coaxially arranged in the machine shell in a sleeved mode from outside to inside, the outer stator and the inner stator are fixedly connected with the machine shell, and the rotor can rotate around the axis relative to the outer stator and the inner stator; the outer stator is provided with a first outer stator three-phase winding and a second outer stator three-phase winding, the inner stator is provided with a first inner stator three-phase winding and a second inner stator three-phase winding, and the first outer stator three-phase winding, the second outer stator three-phase winding, the first inner stator three-phase winding and the second inner stator three-phase winding can jointly drive the rotor to rotate. The output torque is high, the power density is high, the error-tolerant rate is high, and the reliability is high; when a fault occurs, the power density before and after the fault can be basically kept unchanged through a corresponding regulation and control method, and high-power-density constant output is realized.
