IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.Outer rotor variable reluctance resolvers (OR‐VRR) are customised and optimised for electric aircraft to provide precise rotor position detection, which is crucial for control systems. This study enhances OR‐VRR accuracy by refining the stator design through optimisation techniques and simulations.
