ABSTRACT:
A circuit arrangement for starting a trackbound electric propulsion vehicle having a synchronous linear motor without iron in which the motor's stator is a traveling-field winding installed along the track. The exciter of the motor is a translator arranged on the propulsion vehicle, preferably as a superconducting magnet coil. The traveling-field winding is powered, section by section, from stationary, controlled, static converters at voltages and frequencies which can be varied by a control device. The relative position of the exciter with respect to the traveling-field winding and the travel velocity are determined by a computing circuit from the phase currents and voltages at the feed point. In starting, the control circuits of the control device are opened and a starting circuit is added instead. The starting circuit determines the required thrust, the travel velocity, and the exciter position relative to the traveling-field winding from a velocity reference value controlled by a start-up generator. A signal for damping the control component determining the thrust is derived from a measured value of thrust. In this manner, the starting of the propulsion vehicle is made possible without the motor falling out of step or the occurrence of undesirable hunting.
