Evaluation of neighboring phase coupling effects of switched reluctance motor with dynamic modeling approach

This paper reports a method of evaluation of the neighboring phase coupling effects of switched reluctance motor (SRM) using dynamic modeling approach. The dynamic model of the SRM is developed using a few sets of finite element method (FEM) computed phase flux linkage/current/position data under the condition of simultaneous excitation of two neighboring phases. The combination of piecewise Hermite cubic spline and Fourier series techniques is used to represent each FEM-calculated flux linkage data set. The model is ready to be incorporated with various converter topologies and control strategies. It can provide valuable information for motor design evaluation and its controller design evaluation.
