Abstract

The torque motor is the most common technology used in electrohydraulic two-stage servovalves to drive the hydraulic pilot stage. As it is a key component in these valves, its performance considerably affects the overall performance of servovalve systems. Modeling accurately the magnetic behavior of the torque motor will help to get a more realistic performance of the servovalve at different operating conditions during the product design and development stage. In this paper, an advanced model of the torque motor is presented. The aim is to integrate it into the overall multiphysics model of the servovalve through a multi-variable function obtained using the proposed modeling tool. The advanced reluctance network model has been developed by progressively considering various magnetic phenomena, including flux leaks between different parts and variations in magnetic induction. This model allows rapid assessment of the magnetic performance at various operating temperatures or using different ferromagnetic materials, without the need for additional analysis in 3D finite element software.

3. Three-Dimensional Analytical Model of Servovalve Torque Motor Using Reluctance Network

Author

Ribout, Marion, Henaux, Carole, Llibre, Jean-Francois, Messine, Frederic, and Attar, Batoul

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.

Abstract

An approach for electrical machines design by using magnetic field computation coupled to factorial experiments is presented is this paper. Principles of factorial experiments are briefly reviewed and their application to design optimization is explained. In this application, experiments are replaced by magnetic field calculations. The procedure, which performs autmatically all the required numerical field calculations, is described. The whole procedure is applied to a typical problem concerning permanent magnet motors with polar pieces.
