Abstract

A cage rotor of a rotary asynchronous machine includes an axially laminated core having substantially axially extending grooves, at least one electrical conductor disposed in the grooves and composed of at least of two partial conductors constructed from materials having different electrical conductivities and different mechanical strengths, wherein the partial conductor made of the higher-strength material is disposed radially farther outwardly at least in sections of the groove, as viewed along the axial extent of the respective, and a short-circuit ring arranged on a respective end face side of the laminated core and electrically-conductively interconnecting the electrical conductors that are disposed in the respective grooves and protrude axially from the laminated core.
