Embodiment Construction

[0028] figure 1 The vehicle 1 is shown schematically in an extremely simplified manner.

[0029] The vehicle 1 comprises an electrically commutated electric motor 2 , which in the present exemplary embodiment together with a transmission 3 of the vehicle 1 forms a gear motor GM and is actuated by a control unit 4 .

[0030] The transmission 3 is, for example, an automatic vehicle transmission, the driving position of which is adjusted by means of the electric motor 2 .

[0031] Electric motor 2 is electrically commutated and is therefore designed as a brushless motor. The electric motor 2 is actuated via the control unit 4 , which for this purpose has, for example, pulse-width modulation-operated power electronics (not shown here).

[0032] As described at the outset, the power electronics includes three voltage dividers, which divide the input voltage (for example, the 12 V supply voltage of the on-board electrical system of the vehicle 1 ) into three phase voltages, which ...

Abstract

The invention relates to a interference suppression module (5) for an electrically commutated electric motor (2), wherein the interference suppression module has the following components: - a circuit carrier (5.1), - an electronic circuit arrangement arranged on the circuit carrier (5.1) (5.2), - an enclosure (5.3) of shape and material fit surrounding the electronic circuit arrangement (5.2), and - a control unit provided for connecting the electronic circuit arrangement (5.2) to the electrically commutated electric motor (2) (4) At least one interface (5.4) for electrical contact. The invention also relates to a method for producing such an interference suppression module ( 5 ) and a vehicle ( 1 ) with such an interference suppression module ( 5 ).

Description

technical field [0001] The invention relates to an interference-removing module for an electric commutation motor. The invention also relates to a method for producing such an interference suppression module and a vehicle with such an interference suppression module. Background technique [0002] Electrically commutated motors are well known and are characterized by a reduced number of wearing parts compared to brush commutated motors. Such electric motors are used, for example, in vehicle transmissions which are combined with one another to form a transmission motor. [0003] Such an electric motor is actuated, for example, by means of pulse-width-modulated power electronics that are integrated in a controller (eg, a transmission controller). The circuit of the power electronics includes three voltage dividers which divide the input voltage (for example the 12 V supply voltage of the vehicle electrical system) into three phase voltages which are each offset in time from o...
