N2 - The E-core flux-switching permanent magnet (FSPM) machine has gained significant attention recently because of its inherent flux-focusing stator PM topology, robust rotor structure, and improved fault-tolerance capability. However, the torque is restricted as the utilization ratio of the stator iron core is low. Therefore, this analysis proposes two stator dual-PM FS(SDPM-FS) machines to address this issue. Extra PMs are introduced on the stator teeth to enhance the torque production ability. PMs with radial magnetization direction are placed on either the main or fault-tolerance stator teeth. The generation mechanism of the back electromotive force (EMF) is analyzed using the flux modulation effect, which reveals the improvement of working harmonics compared to an E-core FSPM machine. Furthermore, this paper provides a comparative study between the SDPM-FS machines and the conventional FSPM machines. The results demonstrate that the SDPM machines achieve notable enhancements in output torque and efficiency.
