Abstract

This paper presents developing an analytical model for flux switching motors. The motor is a class of variable reluctance motors that has two windings on stator; a field winding and an armature winding. Due to saliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinear behavior of the machine. This paper presents a simple model which is able to predict the motor inductances. The advantage of this method is that it describes the parameters of motor based on its dimensions. The model predicts both the self and mutual inductances. In comparison with similar studies, the proposed model predicts the mutual-inductance of a flux switching motor very accurately. It should be noted that the mutual-inductance has not previously been considered by others in their analytic modeling of variable reluctance motors. The predicted results computed by the proposed analytic model are compared to that obtained by the two-dimensional finite element analysis.
