Abstract

A drive shaft of a dynamoelectric machine includes at least two different heat conduction paths that are thermally separate from one another. Each of the at least two heat conduction paths has two physically separate ends and is embodied such that heat is able to couple into the drive shaft at a first one of the two ends and to couple out of the drive shaft at a second one of the two ends.
