Abstract (en)
[origin: DE19909109A1] The invention relates to a method for detecting a movement, notably for controlling the speed at which an armature arrives at an electromagnetic actuator. Said actuator comprises at least one electromagnet which has at least one pole face and is connected to a controllable current supply, and an armature which is connected to a control member to be actuated and when the electromagnet is supplied with a current can be moved against the force of a return spring from a first switching position in the direction of the pole face of the electromagnet into a second switching position assigned to said pole face. Via at least one direction sensor assigned to the electromagnet the alignment of a magnetic leakage field, which changes as the armature approaches, is detected and a control signal for the current supply is generated in accordance with the change in alignment.
