Abstract

Ein Verfahren zum Vermindern der Geräuschentwicklung bei der Betätigung von elektromagnetisch betätigten Vorrichtungen, wobei ein Schaltvorgang der Vorrichtung im Bereich einer Übergangsfunktion mit begrenzter Steigung der Strom-Zeit-Kurve des Elektromagnets erfolgt, dadurch gekennzeichnet, daß die Übergangsfunktion nur einen Teilbereich der Stromvariation zum Veranlassen eines Schaltvorgangs umfaßt, und daß zeitlich vor und nach der Übergangsfunktion ein im Vergleich zur Übergangsfunktion steilerer Anstieg des Stroms von einem Minimalwert bis zur Übergangsfunktion bzw. von der Übergangsfunktion bis zu einem Maximalwert des Stroms vorgenommen wird. Ein Vorteil liegt darin, daß der Elektromagnet mit einer geringstmöglichen Energie geschaltet werden kann.

Figure 00000001
A method for reducing the noise when actuating electromagnetically actuated devices, wherein the switching operation of the device takes place in the area of a transition function with a limited gradient of the current-time curve of the electromagnet, characterized in that the transition function only a part of the current variation for causing a Switching process includes, and that before and after the transition function, an increase in the current from the minimum value to the transition function or from the transition function to a maximum value of the current is steeper compared to the transition function. One advantage is that the electromagnet can be switched with the lowest possible energy.
