Abstract
An electric motor drive unit for motor vehicle applications, which is equipped with an electric motor having an output shaft substantially circular in cross-section and with a drive element mounted on the output shaft, preferably made of plastic. The output shaft engages a receiving hole of the drive element defining at least one vent hole. According to the invention, the output shaft has, in one variant, at least in the engagement area of the receiving bore, two ridges that are spaced apart from one another and extend axially. A protrusion of the drive element engages between the ridges for rotational coupling. Furthermore, the two ridges each describe a vent hole on the outer edge.
