Abstract

A squirrel cage rotor for an asynchronous machine includes a magnetically conductive main body which is mounted for rotation about an axis and includes electric conductors in substantially axially extending slots. The electric conductors are electrically contacted by short-circuit rings which are located on end faces of the magnetic main body and configured as a thermosiphon.
