NSK develops world's highest speed bearing for EV motors! https://www.nsk.com/company/news/2020/0318a.html Smaller, lighter motors are being pursued by the auto industry to boost EV efficiency and range. But the smaller a motor gets, the faster its components must rotate in order to maintain the same power output as a larger motor. Current EV motors typically operate at around 12,000-18,000 rpm, but automakers are aiming for a dramatic increase up to 30,000 rpm. NSK, a world leader in bearing technology, has completed development of a new bearing capable of enduring the intense forces in EV motor applications at dmN = 1.4 million (e.g. 35 mm bore diameter bearing at 30,000 RPM). This opens up a whole new world of possibilities in EV, and will considerably advance EV motor downsizing and output, thereby contributing to increased fuel economy (reduced power consumption). Research continues as NSK aims to deliver the leading edge in technology necessary to realize a sustainable society that can coexist in harmony with the global environment. Look forward to another exciting announcement later this year! #NSK #EV #Automotive #Sustainable #Technology #Research
