The record was achieved in a distance of 600 metres.
Chinese researchers have accelerated a 1.1-tonne test vehicle on a maglev track to a top speed of 650 kilometres per hour in just seven seconds over a distance of 600 meters, setting a new world record in the process, according to the research team.
"You can see that at the seven-second mark, the speed has increased to 650 kilometers per hour after 600 meters. This speed index is the highest ever worldwide," said Li Weichao, director of the High-Speed Maglev Electromagnetic Propulsion Technology Innovation Center at Donghu Laboratory in central China's Hubei Province.
According to a report by China Central Television (CCTV), the magnetic levitation (maglev) system, equipped with powerful electromagnetic propulsion and precise speed measurement and positioning capabilities, can bring a vehicle to a complete stop from high speeds within just 200 meters of track.
This powerful acceleration and braking control make the high-speed maglev test track a vital platform for the research, development, and testing for China’s high-speed railway network.
The achievement was made possible by the lab's self-developed high-speed maglev test track that stretches only 1,000 meters in length.
Unlike conventional speed tests that require long tracks, usually 30 to 40 kilometers, the new test track has employed a short-distance acceleration method, which demands ultra-precise speed and positioning measurements.
"The current speed measurement and positioning accuracy can reach up to 4 millimeters," said Li.
"There are numerous potential uses in civilian scenarios. The technology from this test track is already being promoted and used in other research facilities,” Li added.
Li added that the speed of 650 km/h is not the ultimate goal for the test line. "Its typical operating speed is 800 km/h. The entire construction is expected to be completed by the end of this year, and the platform will meet the conditions for acceptance."
