Abstract
This paper presents the operating performance of a two-phase switched reluctance motor with different rotor designs, having different air gap geometries. A two-dimension finite element analysis is used to predict the nonlinear flux linkage characteristics for the different rotor designs. The characteristics are obtained numerically at different rotor positions and different current levels for the rotor designs under consideration and then used to predict the static torque characteristics for these designs. A computer simulation procedure is devised to determine the operating performances for the different motor designs based on the predicted flux linkage and static torque characteristics. A comparison is held from the point of view of the torque developed at different speeds, motor efficiency and torque per ampere productivity of the different designs. The two???stepped air gap design proved the superiority over the other configurations.
