摘　　要：针对一类航空电驱动系统用永磁同步电机参数实验测量困难的问题,提出了一种基于dSPACE系统的永磁同步电机参数测量新方法;文中分析了电机的永磁体等效励磁磁链、电机交轴电感及电机等效铁损电阻的实验测量原理。并结合dSPACE半物理仿真实验平台,实现电机参数的准确测量;实验结果表明,与传统的电机参数测试方法相比,该方法不需要特殊的测试设备和额外的硬件电路,具有测试准确、实现简单、操作方便的特点。Aiming to the trouble of parameters determining for permanent magnet synchronous motor （PMSM） used in an aero electric propulsion system, a novel method based on dSPACE is presented in this paper. The measurement principle for the electric machine equiva- lent iron losses resistance, the permanent magnet magnetizing flux and the q axes inductance are analyzed in detail. These parameters are measured on line through dSPACE hardware--in--loop simulation test bench. Compared with the traditional methods for the electric ma- chines parameters measurement, no other especial devices are used and no extra circuits are designed. The experiment results show that this proposed method is simple and easy to operate with good accuracy.
