Abstract

A rotor for an asynchronous machine includes a laminated core and a short-circuit cage which is at least partially integrated in the laminated core, in which the short-circuit cage is made of rods having or made from a first electrically conductive material and short-circuit rings having or made from a second electrically conductive material. A support ring is provided on at least one of the short-circuit rings and is in mechanical contact therewith. The at least one short-circuit ring and/or the support ring has a contour for creating the mechanical contact, and the mechanical contact is a press fit.
