Harbin Electric Inc.’s linear motor (LM) propulsion system, powering China’s first domestically developed and manufactured LM-driving metro train, was successfully tested and validated at Changchun Railway Vehicles Co. Ltd. (CRC), Changchun, China. The technology is the result of more than two years of joint efforts between Harbin Electric, the Institute of Electrical Engineering of Chinese Academy of Sciences, and CRC. Compared to traditional rotary motor-propelled metro transit, the LM-driving metro train is said by Harbin Electric to provide higher performance efficiency with lower energy consumption. The Harbin, China-based company also claims that the simplicity of the LM propulsion system enables the vehicle body to be more compact, reducing the cross section of underground tunnels by about 40% and accelerating construction of the tracks. The next step for this project is to produce a four-car train set for the Beijing Capital International Airport Link; the company expects to deliver the first four-car train in a few months.
