摘　　要：永磁辅助式磁阻同步电动机是一种具有大凸极比、低空载电动势的内置式永磁同步电机。永磁体的不同安放位置使永磁辅助式磁阻同步电动机呈现出不一样的凸极特性,对电机性能产生影响。首先研究正、负凸极永磁辅助式磁阻同步电动机的矢量关系,接着讨论磁链完全补偿条件下的最大磁阻转矩利用问题,最后通过有限元仿真分析了永磁磁阻电机的空载磁场、参数特点、转矩能力和恒功率范围等。Permanent magnet assisted synchronous reluctance motor（ PMa-SynRM） is a kind of interior permanent magnet synchronous motors with high saliency ratio and low back electromotive force. PMa-SynRM has different saliency features with the different placement of the permanent magnet,which have impact on the performance of motor. In this paper,the vector relations of PMa-SynRM for both the positive and negative salient pole were firstly researched,then the utilization problem of maximum reluctance torque was discussed under the condition that the flux is fully compensated,finally no-load flux,parameter characteristics,torque capacity and constant power range of the PMa-SynRM were presented by Finite Element Analysis（ FEA）.
