Abstract: The invention relates to an electric drive unit for adjustment systems in motor vehicles, more particularly for an electrically operated window winder. The electric drive unit comprises an electric motor, a gear unit into which the extended motor shaft of the electric motor projects, and a current unit with a plug or adequate solder spots. The current unit is designed as an intermediate rail for connecting the electric motor and gear housing. When using a commutator motor, the brush holder of the commutator motor is incorporated in the intermediate rail. The intermediate rail preferably forms a structurally uniform block with the plug, and, when additionally using an electronics unit, also with the electronics unit.
