5GMG201E1 main and auxiliary generator is introduced from GE. It is installed in HXN5 freight locomotive introduced from GE by CRRC Qishuyan Co.,ltd, which is a trunk line freight locomotive in China.It is a three-phase salient pole synchronous motor with horizontal single support structure and coaxial main and auxiliary generator. It adopts single-row cylindrical roller bearing with main and auxiliary generator and slip ring by the two ends of bearing. Rotor support is installed in the frame to support rotor in case of bearing damage prior to motor installing into locomotive.The motor input end is flange directly coupled with diesel engine crank shaft to transmit power.It adopts axial forced ventilation with cooling air inlet above the end cover outside auxiliary generator, a branch line cooling main generator stator and rotor, another branch line cooling auxiliary generator stator and rotor and the cooling air are converged at the rear end of main generator and then discharged at the rear.

1. Separation of three sets of windings for the auxiliary generator to reduce mutual disturbing of electricity consumption in the locomotive.
2. Coaxial main and auxiliary generator to facilitate locomotive configuration
3. Moving the slip ring outside to facilitate carbon brush replacement
4. Adopting steel slip ring, being wear-resistant and no manufacture defect
|
|
1. The auxiliary generator adopts the structure of an iron core and three sets of windings,
able to solve interaction effect between different electricity consumption parts in the locomotive
2. Integrated design of main and auxiliary generator to facilitate locomotive configuration despite the fact that there’s larger space for locomotive design
3. Slip ring is located outside end cover to facilitate carbon brush replacement and make it easy to maintain
4.Steel slip ring is adopted to prevent cast defect and easy wear that happen to copper slip ring.
