Development of an Analytic Model for Flux Switching Motors

This paper presents developing an analytical model for flux switching motors. the motor is a class ofvariable reluctance motors that has two windings on stator; a field winding and an armature winding. due tosaliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinearbehavior 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 modelpredicts both the self and mutual inductances. in comparison with similar studies, the proposed modelpredicts the mutual-inductance of a flux switching motor very accurately. it should be noted that the mutualinductancehas not previously been considered by others in their analytic modeling of variable reluctancemotors. the predicted results computed by the proposed analytic model are compared to that obtained by thetwo-dimensional finite element analysis.
