Measurement and Calculation Winding Parameters for Multi-Phase High-Power Propulsive PMSM with Damping Windings

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.
