RAPID TRANSIT AND THREE-PHASE DRIVES. PROBLEMS, WISHES, POSSIBILITIES

NAHVERKEHR UND DREHSTROMANTRIEBE -- AUFGABEN, WUENSCHE, MOEGLICHKEITEN

DC operated vechicles and multiple units dominate in rapid transit systems. Traction motors with commutator are controlled either conventionally by resistors, which can be switched off step-by-step, or by electronic thyristor-choppers. The technical development now tends to three-phase traction motors. This step offers many advantages, for example economies in energy consumption and maintenance. The new traction technique, at present, offers many positive possibilities in vehicle production which cannot be fully appraised yet. The same applies to the interaction of vehicle techniques and the environment.
