Description
The manufacturer makes generators for diesel locomotives, diesel trains, track machines and special vehicles together with traction generators for mining dump trucks. The generator is coupled directly to the diesel engine and becomes the central source of energy. It feeds the traction motors and the on-board network. Almost every diesel rolling stock unit, apart from the starter battery, needs such a source for stable traction and on-board power supply.
The program covers power from 30 to 5000 kVA at voltages from 400 to 3000 V. The standard version is a self-ventilated synchronous generator with electromagnetic brushless excitation. The electronic excitation and control system also monitors and protects the generator, and the program includes a 24 V digital excitation controller. Induction generators and permanent-magnet synchronous generators are also available.
A characteristic feature is the frameless (housing-free) design with a built-in exciter. The unit can be suspended under the car body or installed vertically in the locomotive engine room. The generators are made in single- and double-bearing versions, the choice depending on the diesel design. The number of poles is 4–8, the degree of protection from IP21 to IP66, the insulation system VPI-180. Brushless excitation without slip rings reduces maintenance on rolling stock. Cooling can be by water, forced ventilation or self-ventilation. For diesel-hydraulic machines there are auxiliary generators with a hydrostatic drive that feed the on-board network.
A self-ventilated generator is cooled by a fan on its own shaft and needs no separate cooling drive. The generators operate on hundreds of rolling stock units in different climatic conditions. Rail machine production at the Dresden plant is certified for welding of railway structures to EN 15085-2. Traction and on-board generators are part of the drive packages of locomotives, high-speed trains, track and special machines, and individual power supply components are developed for mining equipment.
The generators are also selected as a replacement for traction and auxiliary generators of locomotives of the ГП, ГС, ГСТ series and similar, including during modernization of the locomotive fleet. The final choice is made by application and main parameters together with a manager.
