永磁辅助同步磁阻电机良好的运行特性与电机的电感参数密切相关，在电磁方案设计阶段需要对电感参数进行准确计算。介绍了等效交直轴法、静态场法、瞬态场法和冻结磁导率法计算交直轴电感参数的原理，并采用上述四种方法进行了电机交直轴电感参数的仿真计算。进行样机试制，并采用伏安法测试了样机电感参数，将仿真结果与测试结果进行对比，以验证各方法的准确性。结果表明，冻结磁导率法仿真得到的交直轴电感参数与实测结果的误差在3%以内，采用冻结磁导率法的计算结果更为准确。

The good operation characteristics of permanent magnet (PM) assisted synchronous reluctance motors are closely related to the inductance parameters, so it is necessary to accurately calculate the inductance parameters in the electromagnetic design. The principles of the equivalent d-q axis method, static field method, transient field method and frozen permeability method are introduced, and the d-q axis inductance parameters are calculated. The inductance parameters of the prototype are tested by voltammetry experiment. The simulation results are compared with the test results to verify the accuracy of the methods. It is shown that the difference between the simulation results of frozen permeability method and the test results is within 3% and the frozen permeability method is more accurate among the four methods analyzed.
