Traction system developed for faster bullet trains
China has developed a permanent magnet synchronous traction system that will take bullet trains to an ultrafast 500 kilometers per hour (311 mph).
The advanced 690-kilowatt traction system was developed by CRRC Corp, the country’s train-making behemoth. It will soon enter mass production, said Ding Rongjun, a member of the Chinese Academy of Engineering who heads the institute. He said that only a handful of countries are capable of manufacturing the sophisticated apparatus, including Germany and Japan.
Feng Jianghua, deputy director of the institute, said the technology will reshape the high-speed railway industry because traction equipment is the most important part of a bullet train.
Most high-speed trains in service are propelled by alternating current asynchronous motors, a traction system first developed in the 1970s.
