SD50 COMPLETES EMD'S HIGH-ADHESION RANGE

The SD50, Electro-Motive's latest six-axle heavy-haul freight loco, goes into production this summer. Permanent parallel connection of traction motors with no field weakening cuts maintenance costs, while optimum use of adhesion is assured by super-series solid-state control of torque which keeps all six motors close to the limit without allowing excessive slip on any axle. In this way, continuous tractive effort of 426 kN at 16 km/h can be specified with confidence, equivalent to 25 percent adhesion.
