Abstract:
An electrical machine (10), in particular for the adjustment of movable parts in the motor vehicle, having a stator housing (22) which accommodates a stator (12) and a rotor (14), wherein the rotor (14) has a rotor shaft (20) on which a commutator (18) is arranged, which commutator can be energized by means of electrical brushes (20), and the stator housing (22) has an axial opening (24) with an encircling edge (26), through which axial opening the rotor shaft (16) protrudes out of the stator housing (22), wherein an electronics circuit board (PCB) (30), which is populated with at least one interference-suppression element (44), is arranged transversely in relation to the rotor shaft (16), and the electronics circuit board (30), in its circumferential region (31), bears against the edge (26) in a conductive manner in order to form a ground contact with the stator housing (22).
