A Brushless Resonant Exciter Concept for Radial Flux Motors

open access: yesIECON 2025 – 51st Annual Conference of the IEEE Industrial Electronics Society
This paper proposes a novel brushless electrically excited synchronous machine that employs inductive wireless transfer of rotor excitation power through the air gap. The magnetic parts of the machine fulfill the excitation function on top of the torque production, thusly achieving similar compactness as brushed electrically excited synchronous ...
