摘　　要：脉振磁场永磁低速同步电动机是一种新结构原理的永磁同步电动机。由于磁路结构的特殊性，绕组电感参数与一般电机有很大不同，不满足Ｐａｒｋ变换条件。因此，在相坐标下建立电机稳态运行饱和数学模型。并且样机仿真结果与实验结果符合较好，证明该分析模型的正确性；同时从理论和实验两方面证明脉振磁场永磁低速同步电动机能够实现低转速、大功率。Pulsating magnetic field PM low speed synchronous motor is a type of PMSM with novel structure. Because of the distinction of the magnetic circuit, its inductance is different from the common PM motor's, which is not agree with park transform. So the saturated steady operation mathematical model of pulsating magnetic field PM low speed synchronous motor is constructed under phase coordinate system. Moreover, the agreement between simulated and measured results is good, which verifies not only the analytical model's correctness but also the conclusion that the type motor is a low speed and high power motor.
