Abstract

A cage rotor for an synchronous machine includes a laminated rotor core, shorting bars arranged inside the laminated rotor core, shorting rings which are cast onto the laminated rotor core and which electrically interconnect the shorting bars to front sides of the laminated rotor core, and heat pipes introduced into the laminated rotor core in the axial direction such that they protrude onto the front side from the laminated rotor core and protrude into the shorting rings.
