China has developed a new electric motor for 400 km / h high-speed trains
A panel of experts in China has approved a design draft for high-speed trains that could run at a speed of 400 kilometers per hour and will be in service before 2022 for the Beijing Winter Olympics. An intelligent high-speed train connecting Beijing with Zhangjiakou, Hebei Province in northern China, a Chinese official said Tuesday.
This is the world's first high-speed train capable of exceeding a maximum speed of 350 km / h, said Bayin Zhaolu, a senior official in Jilin Province, northeast China, at a press conference by the State Council, the Chinese Cabinet.
Developed by local companies in Jilin, the train will deploy China's own BeiDou satellite navigation system for the first time and offer "impressive capabilities" in the areas of intelligent driving, intelligent service and intelligent maintenance, "said Bayin.
It is expected that the train will go into production by the end of the year.
Jilin companies are also developing a new generation of subways that use world-leading autonomous operating systems, Bayin said. "A subway, made of carbon fiber, could inspect, schedule, drive, stop, turn and wash itself," said the official.
The windows in the train work with a touchscreen display system that allows passengers to watch TV and send texts and images, according to Bayin.
The nation has also prepared plans to build a super-fast maglev between Chengdu, the capital of southwest China's Sichuan province, and the Chongqing community in southwest China, which would run between 600k / h and 800k / h per hour, the Securities Times reported in July ,
A novel traction motor that can drive high-speed trains at a speed of 400 kilometers per hour has been successfully developed by a Chinese company.
CRRC Zhuzhou Electric Co., LTD. announced on Tuesday that it is the first Chinese high-speed trains with a permanent magnet traction system that can support a train speed of 400 km / h and close the domestic technology gap, reported the news agency Xinhua.
Li Guang, deputy director of the traction motor research center of this company, told Xinhua that this permanent magnet traction motor brings many advantages such as higher work efficiency.
Li said that this new engine uses a kind of new rare earth material compared to the traditional traction motor to solve the problem of permanent magnetic loss, and that the new cooling technology can make the interior of the machine more environmentally friendly and equalize the temperature of every part of the machine.
All of the engine's performance indicators have reached the highest international level and are capable of driving China's cross-border high-speed trains at a speed of 400 km / h, according to Xinhua's report.
