The paper describes a numerical method of calculating the transient electromagnetic field in magnetic circuits containing moving conducting parts. The procedure allows determining the field distribution if only the supply voltages are known. The equations of the converter's electro mechanical equilibrum have been taken into account. The procedure has been employed for an analysis of transient states in a fast-acting electromagnetic actuator.
Übersicht
Der Beitrag beschreibt eine numerische Methode zur Berechnung des transienten elektromagnetischen Feldes in magnetischen Kreisen, die bewegte leitende Teile enthalten. Das Verfahren ermöglicht die Bestimmung der Feldverteilung, wenn nur die speisende Spannung bekannt ist. Dabei wurden die Gleichungen des elektromechanischen Gleichgewichts herangezogen. Das Verfahren fand bei einer Analyse des transienten Verhaltens eines schnellen elektromagnetischen Aktuators Anwendung.
