Abstract: This paper proposed a new desigen of the wound rotor line-start permanent magnet synchronous motor(LS-PMSM),and its  principle and structure were discussed in this paper.The design method of the motor was analyzed combined with a special case.The starting performance of the motor was simulated and analysed by Ansoft  software,the simulation results show that,with the change of the rotating speed,the motor can ajust steplessly the rotor external starting resistance in the start process, to improve the starting performance of wound rotor line-start permanent magnet synchronous motor,to reduce the flow of electric current and to Improve start-up performance.
Key words: wound rotor; line-start permanent magnet synchronous motor; rotor resistance
