IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.This study introduces a novel partitioned‐stator flux‐switching permanent magnet (PS‐FSPM) machine design aimed at minimizing permanent magnet consumption compared to traditional PS‐FSPM configurations. This is achieved by inverting the stator arrangement of the conventional outer‐armature/inner‐PM PS‐FSPM, resulting in an outer‐PM/inner‐armature PS ...
