Abstract

For simulation purposes and developing controllers, accurate motor parameters are needed to successfully estimate motor performance. Plenty of research has been done on this issue. However, standard procedures are not established yet. This paper concentrates on the measurement of the most critical parameter for permanent magnet motors, namely motor inductances of such motors. Frequency dependence, current dependence and the effect of the power supply waveform on measurements are investigated. Tests are done both at standstill and under running conditions and thus the results of various measurement methods could be compared. Also the effect of the d-axis stator current on the inductance is investigated. Tests are performed on a surface mount PM motor, for which little work appears to be reported as far as measurements are concerned. It is discovered that the inductance measurements with sinusoidal and PWM supply give very close results. It is recognized that during standstill tests measurements are advisable also by reversing the direction of the stator MMF. It is found that direct axis inductance measurements from no-load running test, with stator current direct-axis component in the magnetization direction, gives very close results to standstill tests. Inductance measurements are done also under load. It is discovered that for accurate results this test must be done at a low supply frequency and with a large phase current.

永磁电机电感测量方法的评价
为了进行仿真和开发控制器,需要精确的电机参数来成功地估计电机的性能。关于这个问题已经做了大量的研究。然而,标准程序尚未建立。本文主要研究永磁电机最关键的参数——电机电感的测量。研究了频率依赖性、电流依赖性以及电源波形对测量结果的影响。测试在静止状态和运行状态下进行,因此可以比较各种测量方法的结果。研究了d轴定子电流对电感的影响。测试是在表面贴装永磁电机上进行的,就测量而言,几乎没有工作报告。结果表明,采用正弦电源和脉宽调制电源的电感测量结果非常接近。人们认识到,在静止试验期间,还建议通过反转定子MMF的方向进行测量。结果表明,当定子电流直接轴向分量处于磁化方向时,空载运行试验的直接轴向电感测量结果与静止试验结果非常接近。电感测量也在负载下进行。为了获得准确的结果,必须在低电源频率和大相电流下进行测试。
