design and electromagnetic analysis of a novel axial-field flux-switching permanent magnet machine achieving improved torque characteristics

This paper introduces a unique rotor pole configuration for an axial-field flux-switching permanent magnet (affspm) machine, focused on minimizing cogging torque (ct), reducing torque ripple (tr), and improving average torque (at). this innovative design is based on the standard rotor configuration of the affspm machine, with a reversed radial pole (rrp) placement that this new topology will be recognized as rrpaffspm. to thoroughly evaluate the proposed design's effectiveness, sensitivity analysis will be conducted to determine the significance of geometric parameters and identify the best topology in comparison studies. extensive 3d finite element analysis (fea) confirms the design's effectiveness, demonstrating substantial reductions in ct and tr, along with an increase in at. these results suggest that the desired rotor pole configuration is a promising solution for high-performance electric machines in demanding different applications.
