Résumé
Electrohydraulic servovalves used in various aircraft systems (flight control system, auxiliary power unit, etc.) are a key element in fluid flow and pressure control. This paper presents a 3D analytical modelling method of the servovalves torque motor electromagnetic performance. This analytical model, based on a reluctance network, allows actuator performance to be quickly evaluated taking into account the complex 3D geometry and the high flux leakage rate.
