摘　　要：分别从等效直交轴和电感矩阵方向研究了异步起动永磁电机电抗参数有限元计算方法。以一台55kW-6P电动机为研究对象,建立其二维有限元计算模型,利用电感矩阵法计算其额定工况下电感矩阵,然后通过坐标变换计算得到其直、交轴电枢反应电抗。并与解析法计算值进行对比分析。This paper researches the finite-element method of calculating the reactance parameters of asynchronously-started PMSM from the directions of equivalent d-and a-axis as well as inductance matrix respectively.Taking a 55kW-6P motor as a research object,the 2D finite-element calculation model is established,the inductance matrix of the motor under the rated working condition is calculated by inductance matrix method,and then the d-and a-axis armature reactance are calculated by coordinate transformation.The results are compared and analyzed with those calculated by analytical method.
