Abstract: Based on the permanent magnet rotor with centrifugal structure of six-phase ten-pole fault tolerant motor,the paper put forward a direct current control method which enabled the output toque with ripple minimization and possessed the capacity of fault tolerant.The control strategy ensured that the speed and average output torque kept invariant and a realization of a smooth handoff from the normal state of six phases to the fault state of five phases,when the motor winding or power electronics were open or short-circuit occurrence.A power of 750 W six-phase ten-pole fault tolerant permanent magnet motor （FTPMM） and its all digital controller were designed and tested.It is proved the reasonableness of motor design and validity of direct current control method by the test of open and short circuit fault of winding.
