System for operating an direct-current motor application for a vehicle

The system has a motor application controller (24) arranged away from a direct current (DC) motor application (21) and comprising a three-phase DC/DC transducer for controlling the DC motor application by DC voltage. The motor application controller is arranged outside a motor compartment (22) and connected with the DC motor application by two lines (31, 32) that are connected with the DC motor application by a two-pole plug (33). An electromotive compatibility filter is arranged at an input-side or an output-side of the DC/DC transducer.
