Abstract

Rotoranordnung (100). Die Rotoranordnung (100) umfasst einen Rotor (105), eine Nut (120), welche auf dem Rotor (105) positioniert ist, wobei die Nut (120) eine Stemmausnehmung (180) aufweist, welche in derselben positioniert ist, einen Rotoranbau (220), welcher innerhalb der Nut (120) positioniert ist, und einen Stemmeinsatz (270), welcher innerhalb der Stemmausnehmung (180) positioniert ist. Die Stemmausnehmung (180) hält den Stemmeinsatz (270) axial fest, und der Rotoranbau (220) hält den Stemmeinsatz (270) radial fest.
