The variable reluctance motor (VRM) is known for its structural simplicity, lower cost and capability of higher specific outputs compared with the AC induction motor. These favourable attributes arise from the way the torque is generated. An asymmetric half bridge would commonly be used as the controller for the VRM. It is also a relatively simple circuit because unlike the requirement with an AC induction motor, the imput current for a VRM would only need to be able to travel in one direction.

In this study, a model is developed to represent doubly-salient magnetic circuits and to fit finite element analysis for the aim of obtaining a set of normalized normal force, tangential force, and permeance variation data. To obtain the desired data FE field solution method is used. The reliability of finite element results have been verified by three steps / first, comparing the numerical results with analytically calculated permeance, second, by solving two switch reluctance motors and comparing the results with the measurements of static torque and flux linkage. The third step is by using the normalized data obtained by solving the model with the aid of an available software that is capable to predict the behavior of switched reluctance motors. Once the reliability of the data is assured, the desired data set is produced and presented in tables.
