Abstract

A rotor for an asynchronous machine has a laminated core and a short-circuit cage at least partially integrated in the laminated core. The short-circuit cage is designed with rods having or consisting of a first electrically conductive material and short-circuit rings having or consisting of a second electrically conductive material. At least one of the short-circuit rings is designed with a support ring, and each support ring is designed as a structure interlockingly and/or integrally cast onto or into the associated short-circuit ring.
