An electrical drive device () includes a control circuit () connectable to a voltage source () on the input side and to an electric drive motor () on the output side. The control circuit () includes two separate return conductors () connected to each other at a single connection point (). One return conductor () is connected to the ground terminal () of the control circuit (). The other return conductor () is connected to a motor converter (), a converter control () and a back-up capacitor (). Due to this arrangement, the currents (i, i) flowing in a back-up circuit loop () and a control circuit loop () are confined to remain within the control circuit () and are separated from a housing (), for example the chassis of a motor vehicle. As a result, the electrical drive device () has low interference emissions.
