Abstract

Die Erfindung geht aus von einem Rotor (6) für eine Strömungsmaschine (2), mit einer Welle (4), einem darauf angeordneten Laufrad (8) und einem Wellenlager (12). Eine verbesserte Rotordynamik kann erreicht werden, wenn das Laufrad (8) zur Welle (4) hin eine Ausnehmung (20) aufweist, in der das Wellenlager (12) zumindest teilweise angeordnet ist.
