Abstract
A DC motor for driving components of a motor vehicle includes a housing radially surrounding a stator and a rotor. An end plate axially bond to the DC motor comprises a center which has a drive shaft project there-through, and two connection contacts projecting therefrom which supply a voltage to the DC motor. A printed circuit board has electronic components providing an interference-suppression arranged thereon. The printed circuit board comprises conductor paths, a central opening having the drive shaft projects there-through, and two plug-through openings having the two connection contacts project there-through. An earth connection device producing an earth connection of the printed circuit board is provided as a metal sheet arranged axially between the printed circuit board and the end plate. The metal sheet comprises a first contact element connected to the housing, and a second contact element connected to the conductor paths of the printed circuit board.
