A stator in an electric motor comprises a stator part configured as a hollow body, the part comprising a receiving space for receiving a rotating armature. The walls of the stator part are made of a magnetically conductive material and carry a magnet. In the circumferential direction, the walls of the stator part have a varying wall thickness, which is tapered in the region of the magnet and is configured in a reinforced manner, at least in some sections, in the region outside of the magnet. The stator is designed to have at least two parts, comprising an interior and an exterior stator part, wherein at least one of the stator parts has a varying wall thickness in the circumferential direction.

The invention describes an electrical machine comprising an armature (20) with armature slots (24) for accommodating armature coils and a commutator (10) with commutator laminates (11), wherein at least one armature coil is formed from two coil elements (25, 26), which are arranged symmetrically with respect to one another in relation to the axis of rotation (21) of the armature (20). The electrical machine is characterized in that the number of commutator laminates (11) is an integral multiple of the number of armature slots (24).

The present invention relates to a sliding-contact holder (8) for an electric motor, which has a cylindrical motor housing (1), a front housing cover (2), a rear housing base (3), a rotor shaft (4), a rotor (5), a commutator (6), a stator (7) and a sliding-contact holder (8). The sliding-contact holder (8) comprises at least two holder elements, which each bear at least one sliding contact (11). The two holder elements are inserted individually into the cylindrical motor housing (1). Owing to its design, the sliding-contact holder (8) saves on space and can easily be inserted into the motor housing (1).

According to the invention, the cover consists of a metallic base plate (2) and conductor tracks (18) that are embedded in plastic. The aim of the invention is to simplify the injection moulding process. To achieve this, the invention provides a plastic part (5) with embedded conductor tracks (18), said part having a head region (6) that is configured as a plug and a flat expanded foot region (7). The part is guided through an opening (14) that is configured in the base plate (2) from the underside of the cover, in such a way that the flat areas of the foot region (7) engage behind the opening (14) and lie tightly against the underside of the cover.
