China has developed a permanent magnet traction motor for trains with speeds up to 400 kph, the developer said.
The newly-developed TQ-800 permanent magnet traction motor is expected to be used in a multinational interconnected high-speed train project, according to the CRRC Zhuzhou Electric Co., Ltd.
CRRC Zhuzhou Locomotive Co., Ltd. is one of the electric locomotive manufacturers in China. It is one of the subsidiaries of CRRC.
Adopting a fully-enclosed and directional cooling structure, the TQ-800 motor boasts high power density, excellent low-temperature adaptability and low maintenance cost, the company said.
The successful development of the motor breaks the monopoly of foreign technologies in this area and lays a solid foundation for the upgrade of rail transit technologies in China, it added.
The maximum speed of China’s bullet trains rose to 350 kph when the Fuxing (Rejuvenation) bullet trains started operation between Beijing and Shanghai on Sept. 21, 2017.
The Fuxing trains are a substantial upgrade on the previous Hexie (Harmony) bullet trains. Entirely designed and manufactured in China, the Fuxing train is more spacious and energy-efficient, with longer service life and better reliability.
Fuxing is a series of high-speed and higher-speed EMU trains operated by China Railway High-speed and developed by CRRC, which owns the independent intellectual property rights.
