چکیده :

This paper presents an innovative outer-stator permanent magnet (PM) motor based on the flux-switching (FS) principle. The key novelty of the proposed design lies in the use of segmented stator-pole PMs, which significantly reduces the amount of PM material required compared with conventional outer FSPM machines. To further enhance the electromagnetic performance, a genetic algorithm is employed to optimize the design, aiming to maximize torque output while minimizing torque ripple. The proposed configuration is benchmarked against a conventional outer FSPM topology to emphasize its advantages. Finite element analysis (FEA) results demonstrate that segmenting the PMs reduces torque per magnet volume by 27.3% and effectively alleviates PM saturation issues. Therefore, the proposed topology offers high suitability for applications demanding high torque density.
