Cooled rotor of an asynchronous machine

摘要

The squirrel-cage rotor has a rotor laminated core (1), short-circuit stabs (2) arranged within the rotor laminated core and a short-circuit ring (3) casted to the rotor laminated core, which electrically interconnects the short-circuit stabs at the front faces of the rotor laminated core. The heat pipes (4) are inserted in the rotor laminated core in axial direction. An independent claim is also included for a method for producing squirrel-cage rotor.
