2D magnetic equivalent circuit model of an electronic valve actuator

This paper deals with modeling, based on magnetic equivalent circuit (MEC), of a linear actuator intended for the control of electromagnetic valves. Adopted technique uses a permeance network obtained through meshing considered topology with 2D elementary blocks. Such technique permits to take into account the saturation behavior of ferromagnetic materials composing actuator elements. Force applied on valves is calculated then compared to corresponding finite elements (FE) computation. It has been found, that developed model provides values very close to FE ones but with much less time.
