Minimizing the permanent magnets (PMs) consumption while maintaining the performance of the machine is highly important in the new designs. This paper seeks a structure for PS-FSM with a reduced PM volume, ensuring the maintenance of the torque density and minimizing torque ripple. First, based on the existing partitioned-stator flux-switching permanent-magnet machines (PS-FSPM), a preliminary topology is proposed. The split ratio (SR) and the number of rotor teeth are optimized for the proposed machine and compared with the conventional structure. The finite element analysis (FEA) is employed for the simulation study. The FEA results reveal that the studied machine offers more desirable PM consumption with acceptable torque density and less torque ripple. Second, the primarily proposed topology is modified and a DC field excitation is considered to achieve a final structure with a hybrid-excited machine. The flux-enhancing and flux-weakening capabilities are analyzed for the modified structure.
