China high-speed railway successfully entering permanent magnet driving era

Neodymium Permanent Magnets Manufacturer – China Rare Earth Magnet Limited 

TQ-600 high speed EMU permanent magnet synchronous traction motors attracts much interest in Germany.

It is reported by Science and Technology Daily (Cao Shuwei) on Sept. 23rd that TQ-600 high speed EMU permanent magnet synchronous traction motors, on behalf of the development direction of future high-speed railway traction dynamics, makes its appearance at Innotrans, the biggest global exhibition for rail transit industry. Manufactured by CSR Zhuzhou Motor Co Ltd., the high-end motor is the brainchild when China successfully enters neodymium rare earth magnet driving era. With its internationally leading technology, it attracts much interest of customers in this industry worldwide as soon as it is on display.

As an international leader in the respect of insulation and ventilation, this product, made of a new type of rare earth permanent magnet material, effectively resolves a global tickler---loss of excitation of neodymium magnet. Its insulation technology combines the advantages of insulation structure of high-power locomotives and high-speed rail traction motor, having higher reliability of insulation. Also, its new sealed ventilation design guarantees the cleanness inside of motor cooling system. A train with 8 carriages, for example, adopts TQ-600 permanent magnet motors, which can increase its power by 65% of single motor, enabling its power to reach 600KW, even to 635KW. The total amount of motors will decline from 24 to 13, with an increase of power density of single motor. In this way, the weight of single motor will fall by a third, and the total weight of train motors will decrease by more than 3,100kg, equivalent to the weight of 50 adults. For a daily round trip of Beijing-Shanghai high-speed railway, it saves power energy by more than 1000, 000kw, further improving the competitive advantages of energy conservation, emission reduction, safety and comfort of Chinese high-speed railway.

It is understood that Innotrans is held every two years, founded in 1996 and it is the tenth exhibition this year. Innotrans is the biggest international exhibition with the fastest development and most professional audience in railway industry. As an energy-saving and environment-friendly transportation, railway transit has many advantages, such as, small area, low energy consumption, large carrying capacity and all weather. Therefore, governments all around the world make large scale investments in railway transit. According to CER, the top railway industry organization, the total amount of global railway market is 103.3 billion EURO, among which 71.8 billion EURO is attainable. Railway industry will be on rise in a decade, whose annual increase will reach 1.5%-2% by forecast, and in the next decade the railway market will be increased by 20%.
