3D FINITE ELEMENT MODELLING OF A PERMANENT MAGNET ELECTROMAGNETIC VALVE ACTUATOR

Abstract − The paper presents three-dimensional magnetic field modelling of a recently developed electromagnetic valve actuator with soft magnetic mover and stopper. The permanent magnet is employed in the actuator construction in order to reduce the energy consumption. Three-dimensional finite element method using magnetic vector potential formulation with edge elements is employed. Results are obtained for the magnetic field distribution and the static force of the actuator. Force-displacement characteristics for different values of the magnetomotive force and different lengths of the stopper are also obtained
