Die in der Lebensmittelindustrie eingesetzten Mischmaschinen dienen der bertragung mechanischer Energie von den dynamischen Elementen der Maschine auf das Mischmedium. Weltweit werden Mischmaschinen mit Asynchronmotoren und statischen Spannungs- und Frequenzumrichtern betrieben, was die M glichkeit der Anpassung der Arbeitsparameter an die Erfordernisse des technologischen Prozesses gew hrleistet. Moderne Mischmaschinen sind mit einem Spannungs-/Frequenzwandler ausgestattet, der es erm glicht, die Drehzahl des Elektromotors in einem weiten Drehzahlbereich zu ver ndern. Das Vorhandensein des CTF-Wandlers erm glicht die nderung der Drehgeschwindigkeit der Mischarme. In Anbetracht der Notwendigkeit, einen variablen Drehzahlbereich der Mischvorrichtungen zu erhalten, ist die Regulierung der Drehzahl des Antriebsmotors ein besonders wichtiger Fall beim Betrieb einer Mischmaschine. Die Simulation des elektromechanischen Antriebssystems wird durch die Anwendung des MATLAB-Dienstprogramms und der Erweiterungen von Simulink-Sim Power Systems wesentlich erleichtert. Der mathematische Ansatz, der auf mathematischen Modellen und einer anschlie enden numerischen Simulation basiert, f hrt zu einem wesentlich geringeren finanziellen Aufwand als experimentelle Ans tze.
