Abstract
Official abstract text for this publication.
A method for driving an inductive actuator having an actuating element and an actuator coil, includes initially acting on the actuator coil with a voltage having a first value in order to move the actuating element counter to a spring force and acting on the actuator coil with a voltage having a greater, second value at the beginning of the movement of the actuating element. The second voltage value is selected in dependence on how quickly the actuating element is intended to be moved.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for driving an inductive actuator, the method comprising the following steps: providing the inductive actuator with an actuating element and an actuator coil; applying a spring force to the actuating element; initially acting on the actuator coil with a voltage having a first value to move the actuating element counter to the spring force and acting on the actuator coil with a voltage having a greater, second value at a beginning of a movement of the actuating element; and selecting the second voltage value in dependence on how quickly the actuating element is intended to be moved. 2. The method according to claim 1 , which further comprises carrying out the step of selecting the second voltage value in dependence on a value of a current at which the actuating element begins to move.
