Abstract

Die Erfindung betrifft eine Arbeitsmaschine (1), die direkt oder indirekt verbunden ist mit einem Motor (2), wobei eine Kraftübertragung vom Motor (2) auf die Arbeitsmaschine (1 ) mit mindestens einen durch magnetische oder elektromagnetische Felder angetriebenen Rotor (4) erfolgt, insbesondere ein Rotor zum Antrieb von Strömungsmaschinen, wobei der Rotor (4) mit Permanentmagneten (3) ausgestattet und für einen Betrieb in einer chemisch aggressiven Umgebung ausgebildet ist. Der Rotor (4) und eine damit verbundene Welle (6, 6.1, 6.2, 6.3) sind einteilig aus einem korrosionsbeständigen Edelstahl aus der Gruppe ferritisch-austenischer Duplexstähle hergestellt und am Rotor angeordnete Permanentmagnete (3) sind vor chemischen Angriffen geschützt.
