Embodiment Construction

[0037] figure 1 A motor vehicle 2 is shown schematically in simplified form, which includes an electric motor 4 . The electric motor 4 is designed brushless and has a stator 6 with a total of three electrical phases 8 each having a certain number of electromagnets 10 in the form of electrical coils. The electrical phases 8 are interconnected in a star circuit and are therefore led to a common star point 11 . In addition, the electrical phase 8 is in electrical contact with the electronic device 12 . During operation, the electrical phase 8 and thus the electromagnet 10 is energized by means of the electronics 12 , by means of which a rotating magnetic field is established. In this case, a continuously excited rotor is moved by means of a rotating magnetic field. All in all, the electromagnet 10 of the electric motor 4 is energized by means of the electronics 12 .

[0038] The motor vehicle 2 also has an on-board electrical system 14 , by means of which the electric motor 4...

Abstract

The invention relates to an electronic component (12) of an electric motor of a motor vehicle, which has a coupling unit (24) which is in electrical contact with a printed circuit board (18) and is bonded to the printed circuit board. The coupling unit (24) has several lead frames (26) which are stabilized relative to each other. The coupling unit (24) at least partially forms the coupling plug (32) for the mating plug (34), and the coupling unit (24) at least partially forms the electromagnet (10) for the electric motor (4) contact point (28). The invention also relates to an electric motor (4) of a motor vehicle (2) and a method for producing an electronic device (12).

Description

technical field [0001] The invention relates to the electronics of an electric motor of a motor vehicle. The invention also relates to an electric motor for a motor vehicle and a method for producing an electronic device. Expediently, the electric motor is designed to be brushless, and the electronics are adapted in particular to this electric motor. Background technique [0002] Motor vehicles usually have a plurality of auxiliary units, which are designed, for example, as actuating drives. First of all, these auxiliary units are not only used to propel the motor vehicle, but rather are used to influence other functions of the motor vehicle. In particular, these auxiliary units serve to increase comfort. In particular, therefore, the window regulators and / or the roof are mostly designed electrically and the actuation of the transmission also takes place automatically. [0003] For this purpose, the auxiliary unit usually has an electric motor, which is designed, for exa...
