Aiming at the structure and characteristics of the rim driven motor(RDM), the six-phase fault-tolerant permanent magnet motor(FTPMM) was applied in the rim driven system to deeply study the direct torque control(DTC) strategy of the six-phase permanent magnet fault-tolerant rim propulsion motor.By referring the SVPWM control strategy of three-phase permanent magnet fault-tolerant motor, the flux linkage fault-tolerant compensation was carried out for each phase of the motor to realize the direct torque control of six-phase permanent magnet fault-tolerant wheel-rim propulsion motor under single-phase open-circuit fault. At the same time, the simulation was carried out by using MATLAB/Simulink to compare with the bang-bang control strategy of six-phase permanent magnet fault-tolerant motor,which verified the feasibility and unique superiority of direct torque control strategy based on SVPWM as the fault-tolerant control method of six-phase permanent magnet fault-tolerant motor under open-circuit fault.
