Abstract
An electrical drive unit has a housing having a metal pole housing, which accommodates a stator and a rotor, and a separately produced electronic housing which axially adjoins the pole housing and accommodates an electronic unit. At least one contact element is integrated inside the electronic housing and forms, via at least one ground pin, an electrically conductive connection between the electronic housing and the pole housing to establish a ground connection. An open flange and a cylindrical circumferential wall are formed on the pole housing, against which circumferential wall the at least one ground pin radially bears in a resilient manner, and the at least one ground pin has a side surface facing the circumferential wall, wherein a bearing contour is formed on the side surface and bears against the circumferential wall only in an approximately punctiform manner with respect to an axial direction and/or a circumferential direction.
