Abstract (en)

The noise prevention method has the gradient of the current characteristic of the operating current supplied to the electromagnet (3) controlled so that the current rises rapidly from a minimum value before the transition function and rises rapidly to a maximum value after the transition function, with a lower current gradient over the transition function. An Independent claim for an operating noise prevention device is also included.

Abstract (de)

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. <IMAGE>
