Localized Faraday patterns under heterogeneous parametric excitation
, 2019 Faraday waves are a classic example of a system in which an extended pattern emerges under spatially uniform forcing. Motivated by systems in which uniform excitation is not plausible, we study both experimentally and theoretically the effect of ...

A Brushless Resonant Exciter Concept for Radial Flux Motors
IECON 2025 – 51st Annual Conference of the IEEE Industrial Electronics SocietyThis 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 ...
