Abstract: Aiming at the problems of the fault tolerant operation for open circuit failure of multiphase motor control strategy and its validation, the fault tolerant strategy of five phase permanent magnet motor with one stator winding was opened,a model of five phases motor which was built up in the matlab and the validation of current fault tolerant strategy were studied. Based on the principle of magnetomotive force which was constant, using the basic trigonometric functions,the fault tolerant strategy of five phasess permanent magnet was deduced in details when a winding was opened. A model of permanent magnet motor was established in the Matlab in order to verify the correctness of the current fault tolerant strategy. The results show that the fault tolerant strategy is corrent, and using the model which is builded up in the Matlab, the current fault tolerant strategies of multiphase motors can be verifyied easily.

Key words: five phase permanent magnetic synchronous motor (FPMSM); a phase open; fault tolerance; trigonometric function; Matlab simulations
