Title: Optimization of an axisymmetric linear electromagnetic valve actuator Keywords: Electromagnetism, Finite element analysis, Optimization tech Abstract: Purpose The purpose of this paper is to describe the optimization of a permanent magnet linear actuator with soft magnetic mover for electromagnetic valve. The optimization is carried out with respect to the minimal magnetomotive force ensuring required minimum electromagnetic force on the mover.Design/methodology/approach Three optimization factors are employed. The value of the electromagnetic force and the objective function the magnetomotive force are obtained by caring out a full factorial design of experiment. For obtaining the objective function for each parameter combination, nonlinear equation is solved in order to minimize the flux that creates force in backward direction. Thus, several finite element analyses are carried out for each parameter combination. Then, response surface model is created and optimized. The obtained optimal solution is verified again by finite element analysis. Findings The paper finds that optimal actuator has been obtained and its force-stroke char References Issue
