Split Ratio Optimisation of Axial‐Flux Permanent Magnet Machines Under Thermal Constraints: A Yokeless and Segmented Armature Case Study

open access: yesIET 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

Open‐Circuit Magnetic Equivalent Circuit Model for Single‐Side Double‐Row Stator Axial Flux Wound Field Machine

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
In this paper, a 3D open‐circuit magnetic equivalent circuit model is proposed for rapid performance analysis of the SSDRS‐AFWF machine. This model utilises different discretisation levels for the machine components according to the local magnetic saturation condition, and the double‐cross structure is introduced in the air gap to improve the modelling

The Language of Uncertainty: Reading Türkiye's Economic Pulse Through Geopolitical Fog

open access: yesThe World Economy, Volume 49, Issue 1, Page 30-51, January 2026.
ABSTRACT Geopolitical uncertainty is an increasing concern for investors, entrepreneurs, and researchers. Traditional methods of measuring uncertainty often fall short, whereas Artificial Intelligence (AI)‐driven Natural Language Processing (NLP) offers more accurate and competitive options.
