Induktion/Induktionsverlauf im Element¶
Das Skript erstellt ein Modell, führt eine Leerlauf und Lastberechnung durch und wertet die Induktion in einem Element und dessen Verlauf über dem Drehwinkel aus. Der Verlauf wird zur weiteren Verwendung in eine Datei geschrieben.
Befehlserläuterung siehe Datenzugriff auf Element und Anwendungsbeispiele für Induktion und Induktionsverlauf in den Elementen.
