Abstract
The heat pipes 9a provided here in the grooves 9 of the motor side conduct heat to the end of the output shaft 2 and the heat pipes 10a in the grooves 10 of the housing of the power supply to the opposite end. A flow of heat to axially opposing ends is thus produced that always travels away from the power electronics that are arranged approximately in the center of the system.
