ÖBB Class 1043

The ten locomotives of the series in 1043 were the first thyristor controlled electric locomotives of the ÖBB, which were diverted from the series production of the series Rc2 Swedish State Railways (SJ ).

History

The AC motors previously used had reached a capacity limit of 1000 kW per axis. From Sweden promising developments have been reported: In their Rb / Rc machines DC motors were installed with step switch and diode rectifier. Tests with the Rb1 1001 am Semmering, which proved Rc1 1014 at the Tauern railway and Rc2 1049 SJ that better traction utilization was possible with this technology. This prompted an order for ten locomotives at ASEA in Sweden; Completing parts were made ​​despite capacity constraints of Austrian suppliers. 1971 came 1043,001 to 003, the remaining seven locomotives followed within three years.

The number in 1043 was mainly used between Villach and Tarvisio in freight transport. A locomotive was retired due to unrepairable damage accident, the other nine were sold in 2001 to the SJ in Sweden. Of which took over Tagab the five former 1043 006 - 010

Construction

Mechanical Design

The locomotive body is a welded, self-supporting structure. The side walls are reinforced with beads, which are interrupted by four round portholes and a door; edge of the roof towards the fan guards are attached. In the engine room are located centrally, the thyristor and transformer unit - surrounded on both sides of assemblies cabinets for the powertrain and electronics. When driving an ASEA - drive is used, the gears are helical-cut teeth with 26:87. The box rests on a welded steel plate construction, the train and picks up at the front kicker. Frame and locomotive body resting on a balance beam, the four coil springs and two -axle trucks - made in hollow box construction - is. The tensile force transmission takes place located between bogies and balance beam - diagonally arranged - pursuit on the bridge frame.

Electrical Construction

The three large roof gaps carry the two pantographs (type VI), the roof lines and the main switch. A coat transformer feeds the four externally ventilated, eight-pole traction motors with DC choke, which are controlled via a stepless thyristor bridge. 1043.004 to 010 in addition have a thyristor controlled DC resistance brake at 2400 kW continuous power. The safety devices and the braking system in accordance with the ÖBB 1141 series, the locomotives but as the Rc2 were equipped with disc brakes.
