University of New South Wales (UNSW) engineers have created a new high-speed motor that can extend the range of electric vehicles. The design was inspired by the longest railway bridge in South Korea and is capable of speeds up to 100,000 rpm.
The maximum power and speed of 100,000 rpm achieved by this new motor has successfully surpassed and doubled the existing speed record of laminated IPMSMs (Internal Permanent Magnet Synchronous Motor), making it the world's fastest IPMSM ever made with commercially available laminates. materials. Most importantly, the engine is capable of producing very high power density and greatly reduces the use of rare earth materials, which would save on weight and construction costs.
The electric drive system is also scalable, and the power and speed can be adjusted. The researcher adds that it will take about 6-12 months to modify the engine, for example, according to the needs of Tesla.
