摘要
为了充分考虑磁场各次谐波的作用 ,方波推进电动机一般采用相绕组回路的数学模型 ,模型中绕组参数的测量和计算较为复杂 ,其中带阻尼绕组的多相永磁同步推进电动机的绕组电感测量和计算尤为困难。本文在分析了无阻尼绕组多相永磁同步电动机绕组参数测量的基础上 ,提出了测量带阻尼绕组的多相永磁同步电动机电枢绕组参数的相关分析脉冲响应法 ,该方法将确定电动机参数的问题转化为对系统传递函数系统的辨识问题。
In order to take account of the effect of magnet field harmonic,the phase winding loop model is usually used in square wave propulsive motor. In this model,it is a complicated task to measure and calculate the winding parameters,especially for the multi phase PMSM with damping windings,Based on the analysis of the parameter measurement for multi phase PMSM without damping windings,a correlation analysis pulse response method is put forward. By means of this method,the problem of parameter measurement of this kind of motors can be changed to the one of parameter identification of system transfer function. The validity of this method is proved by the experiment results of a twelve phase salient PMSM.
