1. A rotor for an asynchronous machine, comprising:

  • a laminated core; and

    a short-circuit cage which is at least partially integrated into the laminated core, whereinthe short-circuit cage comprisesrods made with or from a first electrically conductive material,short-circuit rings made with or from a second electrically conductive material,wherein at least one of the short-circuit rings is constructed with a support ring,wherein a respective support ring is constructed as a structure which is cast onto or into the respective short-circuit ring in at least one of a positively locking and materially joining fashion,wherein the respective support ring is constructed with, on a surface, a contour for supporting the at least one of the positive locking and the material joining with the respective short-circuit ring, andwherein the contour has a plurality of projections disposed on an inner surface of the contour inside of a peripheral edge of the contour and projecting radially toward a center of the contour.
