Zhuzhou Electric Locomotive Research Institute Limited Company, Zhuzhou Research Institute for short, attached to CRRC Corporation Limited, spent 11 eleven years, did experiments more than 10 million times, accumulated 150 G of data and eventually conquered the third generation of rail transport traction technology, namely permanent magnetic synchronous motor traction system (PM traction system for short in the following passage. Zhuzhou Research Institute completely owns intellectual property right, which will become a powerful strategic tool of China high speed rail to win the market. Permanent magnetic synchronous traction technology will change situation of multiple industry in China, including compressor industry.
On May 16th in 2015, permanent magnet synchronous motors used in Route 1 of Zhangsha Subway are successfully delivered. This is the first time that PM synchronous motors have been applied to a whole train of subway.
Di Rongjun, Chinese Academy of Engineering and general manager of Zhuzhou Research Institute, reveals that so far Zhuzhou Research Institute has successfully developed 690K w permanent magnet traction system that is applicable for high speed trains with speed at 500km per hour and the traction system will soon get into small batch production. This marks that China will become one of the few who master high speed rail permanent traction system technology after German, Japan, France, ext.
Ding Rongjun indicates, “PM traction system with entire intellectual property right owned by China has entered into industrialization. ‘Generation of Permanent Magnetic Traction’ has finally arrived.”
