Abstract
A squirrel-cage rotor of an asynchronous machine includes a laminated core having grooves and positioned in fixed rotative engagement on a shaft, and a squirrel cage including short-circuit rods which are received in the grooves and have opposite front faces, and short-circuit rings which connect the short-circuit rods on the front faces. Shrink rings respectively surround the short-circuit rings at least radially outside and rest on the shaft. A pressure-resistant hardenable plastic is provided in a gap between the short-circuit rings and the shrink rings.
