Abstract
A high current density component of a dynamoelectric machine rotor is cooled by the use of thermosyphons that carry heat from the heat generating element to a cooler part of the rotor. A homopolar generator is shown with a rotor having a core covered by a copper shell that when so cooled by thermosyphons can be operated with substantially longer pulse intervals than previously.
