摘要

The device (10) has a power unit (18) supplying electrical energy for an electrical machine (12) depending on control signals. A control unit (20) is coupled with the power unit by a connecting arrangement (32) for producing the control signals for the power unit. A cooling body (22) dissipates heat from components of the power unit. The cooling body is arranged at a side (34) of the power unit. The connecting arrangement is arranged at another side (36) of the power unit, where one of the sides (36) is turned to the other side (34).
