摘要： The invention relates to an electronic device (1), in particular, an electric machine with integrated power electronics, whereby a simple and reliable contacting of windings (2) with the power electronics with thermal decoupling of the winding (2) from the power electronics is achieved by a connection of the winding wire (3) of a winding (2) to a first electrically-conducting layer (4) by means of a contact point (10). The first electrically-conducting layer (4) is applied to a thermally-conducting and electrically-insulating cooling element (11, 13) and the first electrically-conducting layer is formed such that the thermal resistance between the first electrically-conducting layer (4) and the cooling element (11, 13) is small relative to the thermal resistance of the winding wire (3) between the winding head (9) and the contact point (10). At least one electrically-conducting connection (5) from the first electrically-conducting layer (4) to further electronic components (7, 8) is provided.
