Abstract

The electrical components, such as coils, brush holders and switching elements, which are arranged in the housing (1), are connected in the housing (1), which consists of insulating material, by means of conductor tracks (13) which are formed directly into wall regions (12) of the housing. This simplifies the assembly of the machine. Since the ends of the conductor tracks which form contact-making elements are always located at the same point, the electrical components just need to be inserted and are then immediately electrically connected to one another.
