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.

    本发明涉及电机技术领域,公开了一种双定子容错电机,包括机壳以及从外到内依次同轴套装在机壳内的外定子、转子以及内定子,外定子和内定子分别与机壳固定连接,转子能相对外定子和内定子绕轴线转动;外定子设有第一外定子三相绕组和第二外定子三相绕组,内定子设有第一内定子三相绕组和第二内定子三相绕组,第一外定子三相绕组、第二外定子三相绕组、第一内定子三相绕组以及第二内定三相绕组能共同驱动转子转动,输出的扭矩高,功率密度较高,容错率高,可靠性高;发生故障时,通过相应的调控方法,能确保故障前和故障后的功率密度基本保持不变,实现高功率密度恒定输出。
