[文摘]:The switched reluctance motor (SRM) has evolved into a practical alternative to other machines for a variety of applications. The SRM can be described as a system with two ports, the windings through which electrical power is transferred and the shaft through which mechanical power flows. These systems are coupled by a magnetic system, through which the energy conversion process occurs. The windings can be modeled as an inductor, and much work has focused on the modeling of the SRM inductance. The difficulty with this approach is that the SRM magnetic structures must operate in deep saturation, resulting in a nonlinear winding inductance. In this paper a relatively simple model for the SRM is developed. The machine terminal characteristics in terms of flux linkage are described. It is shown that flux linkage is a function of two variables resulting in a surface function. Additionally, it is shown that this surface function contains the terminal characteristics of the SRM. Finally, measurements from actual hardware are made and used to develop a model using the techniques developed here. The results of the model simulation are then compared with measured data. (AIAA)
