It’s mainly used by the previous DF and DF4 diesel locomotive. The series generator has been exported to Uzbekistan Kazakhstan and North Korea etc. Technical Feature 1.Motor structure: being three-phase salient pole synchronous generator with horizontal single bearing structure, E32626QTY single-row cylindrical roller bearing is installed at shaft extension end with shat extension 1:10 taper to help transmission and the other end is connected to diesel engine by flexible coupling. 2. Ventilation method: It adopts protection radial self-ventilation with cooling air entering from end cover air inlet, blown by scoop-type fan installed at the two ends of rotor, blown by scoop-type fan installed at two ends of the rotor and discharged from two rows of air outlets below and above the frame. 3. Excitation: brush excitation with excitation through brush carrier and slip ring. Technical Advantage 1. To supply traction power for diesel locomotive with medium-speed diesel engine 2. Large power 3. High voltage 4. Wide voltage ratio 5. High insulation class 6. Stable performance
