ABSTRACT:
A propulsion system for vehicles, includes a d-c machine, an armature current control element connected to the d-c machine, an alternating member having an output side connected to the armature control element and having an input side, an armature current control device connected between the input side of the alternating member and the d-c machine for delivering a first armature current reference value to the alternating member, a maximum value formed connected between the input side of the alternating member and the d-c machine for receiving the value of the actual machine speed and the actual armature current from the d-c machine and for delivering a second maximally permissible armature current reference value to the alternating member, the alternating member passing on the smaller of the first and second armature current reference value to the armature current control element.
