Abstract
A rotor device () for an electric machine () has a rotatably supported shaft () and a rotor hub () connected to the shaft () in a rotationally fixed manner. The shaft () has multiple radially outwardly facing shaft protrusions (), and the rotor hub () has multiple radially inwardly facing hub protrusions (). A shaft protrusion () and a respective hub protrusion () abut one another in a touching manner in the radial direction at least in sections. Cavities () are formed between the rotor hub () and the shaft (). The cavities () extend between adjacent shaft protrusions () and the hub protrusions () lying thereon. The cavities () are grouted with a material (). The material () forms form-fit elements () that block relative movement of the rotor hub () and the shaft () in a form-fit manner.
