Ever since the introduction of the semi-bullet train by Modi-ji, China is envious of Indian Railway's progress. Now China has answered back with this new motor, promising to increase bullet train speed to 500km/hr. Can India answer this new challenge? I am confident that under Modi-ji's brilliant leadership, anything can be achieved. India will quickly surpass China to become a bullet train superpower by 2020!

China develops cutting-edge Permanent-Magnet Synchronous Electric-Machinery Traction System for High-Speed Rail
25 Jun, 2015 in Chinese Railways / Rail Enterprise, Industry and OEMs / World RailNews by rail
Beijing: After 10 million test runs, 100 million yuan (US$16.1 million), and over 11 years, the Zhuzhou Electric Locomotive Research Institute (ZELRI) under the auspices of high-speed rail equipment manufacturer CRRC Corp has successfully developed the permanent-magnet synchronous electric-machinery traction system, giving the nation’s high-speed rail industry an extra edge.
The system was delivered on May 16 for use on the trains traveling the No. 1 subway route in Changsha, capital of Hunan province. Ding Rongjun, president of ZELRI and a member of the Chinese Academy of Engineering, said that the company has been able to turn out a 699 kW model for the new system, suited for use on a high-speed rail train with speeds of up to 500 km/h. This puts China in the same category with Germany, Japan and France as one of the few countries that possess such technology, said the report.
The permanent-magnet traction system boasts cutting-edge technology that greatly improves the power quality, energy efficiency and controllability of trains. New cars will be more economical, comfortable and reliable.
ZELRI started research on the advanced traction system in 2003 and has overcome numerous obstacles in the development process. After gain victory over the overheating problem, it produced technology neck-and-neck with a few leading international rail-equipment manufacturers including Siemens and Bombardier.
The system was first installed on a trial basis in late 2011 in some trains on route No. 2 of the subway in Shenyang, Liaoning province in northeastern China. The new equipment operated without any malfunctions for 70,000 kilometers of train travel as of the end of May 2015.
Under the instruction of the central government, ZELRI started the effort in 2011, upgrading the wattage of the system from 190 kW, suited for use in a city subway, to 690 kW, suited for a high-speed rail train with speeds of up to 500 km/h. It successfully rolled out the upgraded model in October 2014.
“We expect to adapt the system on the nation’s high-speed rail trains in the near future,” said Li Yifeng, chief designer of ZELRI, according to the report.
Data show that the substitution of the permanent-magnet synchronic traction system with the existing system will boost the power of the electric machinery of the high-speed rail trains by 60% and cut its degeneration by 70%.
