Embodiment Construction

[0022] figure 1 A longitudinal section of an electric drive 1 according to the invention with a drive module 10 and an electronic module 20 is shown, wherein the drive module 10 includes a motor module 30 and a transmission mechanism module 40. Here, the motor module 30 is shown in a cross-section in the upper part and in a cross-sectional view in the lower part. The brush 37 and commutator piece 38 can be seen in the cut-away section above. In addition, the motor module 30 includes an armature 35, and the armature is connected to the DC grid through a commutator 36. The commutator 36 is connected to the armature 35 through a connecting hook 39. Because when the brush 37 is moved from one commutator segment 38 to the next commutator segment, the corresponding winding inductance is short-circuited by the winding resistance and the brush transition resistance, so the motor module 30 is in operation at every commutation. Spark discharge. On the one hand, this spark discharge sh...

Abstract

The invention relates to an electrical driver (1) for a motor vehicle, which comprises a driving module (10) with a motor module (30), and an electronic module (20). An interference device for the motor module (30) is arranged between the driving module (10) and the electronic module (20). The motor module (30) is provided with an electrode cover (31) used for accommodating a motor. The electrode cover (31) is connected with the motor module (30) through at least one fixing element (50). The fixing element (50) is provided with an additional contact element (51) used for connecting the electrode cover (31) with the bond strap of a vehicle.

Description

Technical field [0001] The present invention relates to an electric drive, especially an electric adjustment drive in a motor vehicle, wherein the adjustment drive also refers to a sliding sunroof drive, a door drive, a rear cover drive, a seat adjustment drive or a window lift drive . Background technique [0002] Such an electric drive is used as an auxiliary drive and / or a comfort drive in a vehicle, for example, as a DC motor, and generally includes a drive module and an electronic module. The drive module may be composed of a motor module and a transmission mechanism module. The drive module usually includes a motor, and its armature (rotor) placed on the motor shaft is rotatably supported in a metal pole cover (Poltopf), and permanent magnets are held in the pole cover in a two-pole or multi-pole arrangement. . Here, the pole cover or the housing is usually supported on the center or end of the armature shaft by means of rolling bearings and fastened by means of fixing el...
