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.

Drive shaft of a dynamoelectrical machine and corresponding manufacturing method

A coil of a stator winding of an electric machine is formed of a number of windings, which are wound together with a number of layers of a mica tape, on which a number of layers of a cover tape are in turn wound. The coil is a three-dimensional form-wound coil. The mica tape has a bending stiffness of less than 50 N/m according to specification IEC 60371-2:2004 and a static friction coefficient between the top side and the bottom side thereof of less than 0.7 according to specification ISO 8295:1995.
