Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0025] FIG. 1 illustrates a schematic view of an embodiment of an electronic module in accordance with the present invention;

[0026] FIG. 2 illustrates a stator, comprising two embodiments of electronic modules for the controller in accordance with another embodiment of the present invention.

DETAILED DESCRIPTION OF THE DRAWINGS

[0027] FIG. 1 illustrates a schematic view of an electronic module 1, comprising a first carrier element 10 and a second carrier element 20. The second carrier element 20 is arranged around the first carrier element 10. For this purpose, the second carrier element 20 comprises two main segments 22 that are arranged essentially parallel to one another, which are connected by way of a connecting segment 24 that is arranged so to speak on the end side with respect to the carrier element 10. The connecting segment 24 is connected to the respective main segments 22 by way of flexible regions 16. The first carrier element 10 is connected to the second carrier element 20 by means of schematically illustrated contact elements, in particular contact pins 50, wherein these are arranged both perpendicular with respect to the first carrier element 10 and also in parallel (for reasons of clarity only one is provided with a reference numeral). The entire surface area of the second carrier element 20 is advantageously “used”. Components 40 are illustrated schematically as black areas and are arranged both on the first carrier element 10 and also on the second carrier element 20, in the present case in particular on both sides. In particular, (the) components 42 that are to be cooled are advantageously arranged on the first carrier element 10. It is preferred that the power electronic components that require to be cooled are therefore arranged there. The first carrier element 10 advantageously comprises a cooling facility which is however not illustrated in the figure. Only connections for a cooling medium are schematically illustrated in FIG. 2. The components 40 that are arranged on the second carrier element 20 are in particular logic and/or control components that do not require to be cooled. In the embodiment illustrated here, the second carrier element 20 is in particular U-shaped or forms such a U-shape. The first carrier element 10 is expediently arranged in the intermediate space or arrangement space 26 that is formed as a result of the U-shape, as a result of which a very compact construction is realized, which reduces the number of required plug connectors and the like to a minimum. The reference numeral 14 also indicates that conductor track contacts can be provided on the first carrier element 10 and these conductor track contacts serve to provide the electrical contact of the first carrier element 10, as also shown in particular in FIG. 2.

[0028] FIG. 2 illustrates a schematic view of at least one part of a drive, comprising an electric machine having a stator 70. The stator 70 comprises a field connection 72 and phase connections 74, wherein these are connected accordingly to two electronic modules 1, wherein for this purpose insert-push contacts 60 are provided. For purposes of cooling the electronic module 1, these advantageously comprise connections for a cooling medium 76. In particular, the right-hand electronic module 1 is still connected by way of a signal contact 64 to a control connection 62. Both electronic modules 1 comprise protective elements 2 that encase in particular the second carrier element, as also shown in FIG. 1. It is preferred that in this case the protective elements are a suitable casting mass.
