ABSTRACT:
A method of operating an electromagnetic actuator having an electromagnet provided with a pole face, an armature movable towards and away from the pole face and a resetting spring exerting on the armature a resetting force urging the armature away from the pole face, includes the steps of supplying current to the electromagnet for generating an electromagnetic force moving the armature towards the pole face against the resetting force; and controlling the current supplying step such that at least along a terminal portion of the displacement path of the armature during its approach toward said pole face, the force/time curve of the magnetic force extends substantially parallel to and lies above the force/displacement spring curve of the resetting spring.
