Abstract

A cage rotor of an asynchronous machine includes a magnetically conductive body having substantially axially running slots with conductors connected to end faces of the magnetically conductive body in an electrically conductive manner by short circuit rings. The short circuit rings have an outer side, an inner side, a front side, and a rear side. A supporting element made of a high-strength material is located at least radially within the short circuit rings, i.e. on the inner face, with the supporting element being connected to the short-circuit ring, at least in one section, with a material fit.
