Article read: Over the past 11 years, a total of 10 million tests accumulated 150G data, cost 100 million yuan, China's Zhuzhou Electric Locomotive Research Institute Co., Ltd. (hereinafter referred to as "Zhuzhou Institute") to capture the third generation of rail transit traction technology , That is, permanent magnet synchronous motor traction system (hereinafter referred to as "permanent magnet traction system"), complete independent intellectual property rights, as China's high-speed rail win market a major strategic tool. "Whoever owns permanent magnet traction system, whoever owns the right of high-speed rail" [Found Chinese original technology] China's high-speed rail used the world's most advanced traction technology China Economic Weekly reporter Cao Chang trainee reporter Li Yonghua | Zhuzhou, Hunan Province It took 11 years and accumulatively 10 million tests to accumulate 150G data and cost 100 million yuan. The Zhuzhou Electric Locomotive Research Institute Co., Ltd. (hereinafter referred to as "Zhuzhou Institute") of China National Trucks has overcome the third generation of rail transit traction technology, Magnet Synchronous Motor Traction System (hereinafter referred to as "Permanent Magnet Traction System"), with complete independent intellectual property rights, has become a major strategic weapon for the Chinese high-speed railway to win the market. On May 16, 2015, the permanent magnet synchronous motor used by Changsha Metro Line 1 was successfully delivered. This is the first time in China will be loaded with permanent magnet synchronous motor train loading and unloading applications in the entire subway. Ding Rongjun, academician of Chinese Academy of Engineering and general manager of Zhuzhou University revealed that at present, Zhuzhou has developed a 690kW permanent magnet traction system that can be used for high-speed rail car with a speed of 500 kilometers per hour and will soon be in small batch production. This marks one of the few countries in the world that have mastered the technology of the high-speed railway permanent magnet traction system after becoming a country like Germany, Japan and France. "China has completely independent intellectual property rights of permanent magnet traction system has taken the pace of industrialization, China's rail transit 'permanent magnet traction era' has finally arrived." Ding Rongjun said. From the "subway" to "high-speed rail use": "Climb Hengshan went to Mount Everest" Traction drive system in the industry known as the "train of the heart," its performance to some extent determines the train's power quality, energy consumption and control characteristics, but also affect the train economy, comfort and reliability, energy saving The key to upgrade. The first generation of world rail vehicle traction system is a DC traction system, the second generation is the AC induction motor traction system started in the 1970s and is the current mainstream technology. According to Feng Jianghua, deputy general manager of Zhuzhou, "For the traction technology of the rail transit, the permanent magnet traction system is a revolution. Who owns the permanent magnet traction system will have the right to speak for the high-speed rail."
