Abstract
The effect of main design geometries on the average torque of double-stator switched flux PM machines (DS-SFPM) is investigated in this paper. Firstly, a genetic algorithm optimization technique is employed in order to obtain the optimum design parameters of each of the investigated machine at fixed copper loss condition. Furthermore, a quantitative comparison of the different stator and rotor pole combinations is also presented. Moreover, the analyzed double-stator machines equipped with different winding topologies is also presented. The analyses are carried out with a 2D-finite element (FEA) analysis. Overall, the analyzed 14-pole machine having all-pole wound topology seems to be the most promising candidate as it exhibits the largest average torque. Above all, the predicted results show that there is an optimum value of each of the leading design elements due to the saturation of the armature reaction.
