Abstract
Electrohydraulic servovalves used in various aircraft systems (flight control system and auxiliary power unit) are a key element in fluid flow and pressure control. This article presents a 3-D analytical modeling method of the electromagnetic performance of servovalves torque motor. This analytical model, based on a reluctance network, allows us to quickly evaluate the actuator performance taking into account the complex 3-D geometry and the high flux leakage rate. This model enables to reduce the performance analysis time by about 89% compared to the conventional 3-D finite element calculation time. This is valuable for the design and optimization of the actuator geometry.
