Abstract: An adjustment drive includes a DC brush motor, a brush card assembly including electrical contacts of brushes with busbars, a Hall sensor assembly, and a transmission. The Hall sensor assembly is on a printed circuit board which is integrated in the brush card assembly. A pin terminal is on the printed circuit board to contact the Hall sensor assembly, and the brush card assembly includes a plug body with a plug collar. The plug body is at least partially penetrated by the pin terminal and the busbars to define a plug.

Abstract: An asymmetrical, direct current excited brushed motor may include a motor shaft; a commutator with a number of lamellae arranged in the circumferential direction; an armature with a number of armature teeth and armature grooves, where anchor windings are arranged in the armature grooves to form coils; at least one brush pair for supplying the coils with power, including two brushes contacting the lamellae; and a number n of permanent magnets in the stator to form a magnetic field, where n is a multiple of 2 and n>2, and where the number of armature teeth is unequal to a multiple of n. A position angle between the brushes of a brush pair is equal to or less than 90° and unequal to a multiple of the position angle between two directly consecutive lamellae.
