China become one of the world's few masters of the high-speed permanent magnet traction system technology
By CSR zhuzhou developed China's first set of "permanent magnet high-speed synchronous traction system" for the first time to complete orbit, and passed the trial operation of the China railway corporation review, is about to start the vehicle type test and running inspection. This is a "permanent magnet high speed railway" in China, marked the country become one of the world's few masters of the high-speed permanent magnet traction system technology.
According to introducing, the high-speed train permanent magnet synchronous traction system containing traction inverter, the network control system, permanent magnet synchronous traction motor, etc., and the first two generation of dc system, asynchronous system, compared with speed stability, high efficiency, small volume, light weight, low noise, high reliability advantages, energy saving can reach more than 10%. Among them, the independent research and development by CSR zhuzhou jd188 type of high-power permanent magnet synchronous traction motor rated power of 690 kw, and is the most powerful domestic rail transit field of Permanent magnetic material synchronous traction motor.
"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
