Abstract
An electric motor vehicle auxiliary unit includes a housing which is at least partly electrically conductive. An electric drive motor having stator-side motor coils, a unit mechanism which is driven by the electric drive motor, and a motor electronics circuit board are each arranged within the housing. The motor electronics circuit board includes motor electronics having control and power electronics which control the electric drive motor, and at least one housing ground connection which is electrically conductively connected directly to the housing via a housing ground element. A punch comb arrangement has at least two plug pins. A plug connection connects the motor electronics circuit board to an engine control unit. The plug connection is electrically connected to the motor electronics circuit board via the punch comb arrangement. The housing ground element is designed as a plug pin of the at least two plug pins of the punch comb arrangement.
