Trac­tion sys­tem de­vel­oped for faster bullet trains

China Daily (Canada) - - FRONT PAGE -

China has de­vel­oped a per­ma­nent mag­net syn­chro­nous trac­tion sys­tem that will take bullet trains to an ul­tra­fast 500 kilo­me­ters per hour (311 mph).

The ad­vanced 690-kilo­watt trac­tion sys­tem was de­vel­oped by CRRC Corp, the coun­try’s train-mak­ing be­he­moth. It will soon en­ter mass pro­duc­tion, said Ding Rongjun, a mem­ber of the Chi­nese Academy of En­gi­neer­ing who heads the in­sti­tute. He said that only a hand­ful of coun­tries are ca­pa­ble of man­u­fac­tur­ing the so­phis­ti­cated ap­pa­ra­tus, in­clud­ing Ger­many and Ja­pan.

Feng Jianghua, deputy di­rec­tor of the in­sti­tute, said the tech­nol­ogy will re­shape the high-speed rail­way in­dus­try be­cause trac­tion equip­ment is the most im­por­tant part of a bullet train.

Most high-speed trains in ser­vice are pro­pelled by al­ter­nat­ing cur­rent asyn­chro­nous mo­tors, a trac­tion sys­tem first de­vel­oped in the 1970s.
