Dynamic characteristics of a permanent magnet electromagnetic valve actuator

The paper presents simulation of the dynamics of a recently developed energy efficient permanent magnet electromagnetic valve actuator. The simulation is carried out using decoupled approach where the 3D magnetic field problem is solved separately from the electric circuit and mechanical motion problems. Finite element method with edge elements and ANSYS program are used for the magnetic field analysis. Dynamic characteristics are obtained in Matlab environment utilizing functions derived from the field analysis. The obtained results are compared with experiment.
