Electromagnetic actuators for electromechanical valve trains are highly nonlinear devices. The understanding and knowledge of their dynamics are essential for a proper use in such application. In this paper, a simple, yet comprehensive model is used to examine the effect of eddy currents on system dynamics. Furthermore, a voltage driven finite element model is established, which implements the nonlinear magnetic material properties with a modified Weibull distribution. Switch-off experiments with an electromagnetic actuator are carried out and the results are compared with the finite element simulations.
