Title:
DEVICE FOR CONTROLLING AN ELECTROMECHANICAL SETTING DEVICE
Document Type and Number:
WIPO Patent Application WO1998055748
Kind Code:
A3
Abstract:
A device for controlling an electromechanical actuator with an actuating element and an actuating drive. The actuating drive includes an electromagnet which has a core and a coil. The actuating drive, furthermore, has a moveable armature plate. A controller is provided, the control variable of which is the current through the coil and the actuating variable of which is a voltage applied to the coil. A voltage source generates a supply voltage and a pulse width modulator modulates the actuating variable as a function of the supply voltage.
