IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This paper investigates the impact of sleeve segmentation on eddy‐current loss in permanent‐magnet (PM) machines with fractional‐slot concentrated‐windings (FSCW) under different stator MMF harmonics. The concept of equivalent sleeve segmentation is introduced.

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.An AFPM (YASA) machine for wind‐power use is analytically optimised for maximum torque by tuning the split ratio (inner‐to‐outer stator‐core diameter), under thermal constraints that account for both copper and iron losses, and the resulting trends are verified by 3‐D FEA and prototype tests. Under a copper‐loss‐dominated limit, the optimal split ratio
