A device comprising an ac machine (1) and control equipment connected thereto, the control equipment comprising heat-generating components such as power semiconductors (5) and other electric components (6). The ac machine comprises a stator body (10) with a cooling channel (13) integrated thereinto for conducting a coolant for cooling the heat-generating components and the ac machine. The cooling channel exhibits an opening towards an outer surface of the stator body, which outer surface limits the stator body in its radial direction, and at least the power semiconductors are arranged in a power semiconductor module (5) with a bottom plate (14), and the power semiconductor module is applied to the stator body over said opening in the cooling channel such that the bottom plate constitutes part of a wall surrounding the cooling channel. |
