Abstract

Beschrieben wird ein Verfahren zur Überwachung einer elektrodynamischen Maschine, insbesondere eines Generators (1), mit einer innerhalb eines Stators (12) längs einer drehbaren Welle (10) gelagerten Rotoranordnung (11), die mit dem Stator (12) einen Luftspalt (17) einschließt, bei dem mittels wenigstens eines innerhalb des Luftspalts (17) oder innerhalb des Stators (12) angeordneten Sensors (18) Messsignale erfasst und ausgewertet werden, die von einem von der elektrodynamischen Maschine erzeugten Magnetfeld abhängen. Das Verfahren zeichnet sich dadurch aus, dass die Messsignale zur Beurteilung der dynamischen Belastung der Welle (10) zugrunde gelegt werden.
