Vorlesung: Electric Drives and Storage Systems

 

Die Veranstaltung "Electric Drives and Energy Storage Systems" im Wintersemester 2021/22 wird institutsübergreifend durch das Lehr- und Forschungsgebiet Mechatronik in mobilen Antrieben (MMP) und das Institut für Elektrische Maschinen und den Lehrstuhl für Elektromagnetische Energiewandlung (IEM) angeboten. Die Vorlesungen werden durch Herrn Professor Andert, MMP und Herrn Professor Hameyer, IEM gehalten.

Ab dem Sommersemester 2022 wird die Veranstaltung durch das Lehr- und Forschungsgebiet Mechatronik in mobilen Antrieben (MMP) angeboten. Sie findet in englischer Sprache statt.
