主　　题：Synchronous reluctance motors torque shifted asymmetrical salient pole analytical method,saturation. 

摘      要：In traditional analytical method(AM),the magnetic saturation is always ignored to simplify the calculation ***,synchronous reluctance motors(SynRMs)often operate around saturation point to achieve higher torque ***,a new AM is proposed,in which the saturation of stator iron has been *** key of the proposed method includes a saturation factor,and an iterative method is adopted to compute the saturation factor in the SynRM by increasing the air-gap ***,the proposed AM can be applied to a SynRM even with *** the process of AM,the expression of stator magnetomotive force(MMF)is built ***,the air-gap density including slotting effect and salient-poles is ***,the rotor MMF under saturation of the stator iron is ***,the precision of the instantaneous torque can be improved ***,by the verification of finite elements method(FEM)and experiments,the torque performance of SynRMs with shifted asymmetrical rotor can be predicted accurately by the proposed AM.
