Technological Characteristics of EMUs Traction Motor Motor Light-Weight Design Motor light-weight design is adopted, making the base weight reduced by 30% and cover weight reduced by 50% compared with the traditional way. The ratio between power and motor weight is raised to 1.14. Technology of High-Speed Rotor The design of conducting bar, guard ring and end ring is optimized to ensure reliable high-speed running of the rotor. Motor insulation Technology Motor insulation system is adopted, increasing the reliability of motor High-Speed Insulation Bearing and Special Lubrication Structure High-speed...

YQ-600 Traction Motor for 500km/h EMUs It is MOR's project in 2010. Motor is designed for test vehicle, with maximum design speed as 500km/h. Intercity EMUs YQ-300 and YQ-275 traction motors are installed in the CRH6- 200km/h and CRH6-160km/h intercity EMUs, which mainly serve as short-distance commuter passenger transport between cities and between urban and suburban areas. The rated speeds are 200km/h and 160km/h comparatively, which could meet the requirement of running speed on the one hand, and that of frequent starting and stopping on the other. Parameters of EMUs Traction Motor

EMUs Traction Transformer Silicone Oil Cooling Grade F Oil-immersed Transformer Cooling insulating medium of traction transformer adopts simethicone oil, winding uses grade-H Nomex insulation paper, major insulation material applies grade-H polyamide A plate, and other insulation materials are not lower than grade-F, which forms the technical system of silicone oil grade-F insulation oil-immersed traction transformer. The successful application of grade-F insulation oil-immersed traction transformer lays a technical foundation for higher grade insulation oil-immersed traction transformer. Light-Weight...
