DES-FR-3000E synchronous main alternator is a new product which is combined of structure of our traditional main alternator and advanced technique of the world. This alternator has high voltage regulating under constant power and can effectively reduce field weakening deep of traction machine. This improves reliability in operation of the locomotives.
The alternator is installed with improved bearing E32626QTY and this makes locomotives more reliable. DES-FR-3000E synchronous main alternator makes replacements and technical innovations of DES-FR-3000 series products. Its overall dimension, installation dimension and excited current are the same as DES-FR-3000B alternator.
