ABSTRACT:
The invention is a converter-fed drive system having at least one drive motor fed by a converter unit. The converter unit has a valve assembly containing semiconductor valves, a cooler for cooling the semiconductor valves and a capacitor assembly are mounted directly on the drive motor. There is also an inductor assembly, that is electrically connected to the converter unit, but is installed such that it is spatially separated from the converter unit and the drive motor. The cooler is simultaneously used to cool the drive motor as well as the converter unit.
