Abstract

An electric drive unit for vehicle systems, such as power windows and windshield wipers, having a commutator motor that has a commutator and at least two commutator brushes. The electric drive unit includes electrical components of an electronic system for the motor. To reduce production costs and simplify assembly, the electrical components are electrically secured to a lead frame that makes the electrical connection between the components and the commutator motor and the commutator brushes are embodied as hammerhead brushes, whose carrier plates are bent in one piece out of the lead frame.
