30,000 RPM and Beyond: Anatomy of a Next-Generation EV Moto

In 2025, EV motors reached a new technological milestone by exceeding 30,000 rpm, according to IDTechEx. While ICE engines typically peak at 5,000–6,000 rpm, EV motors already operate at 10,000–15,000 rpm, covering the full speed range through a single-speed transmission.
Higher speeds enable greater power density and more compact motors, reducing bill of materials and freeing vehicle space. Following Tesla and Lucid (~20,000 rpm), BYD, Xiaomi, and GAC announced motors above 30,000 rpm in 2025. IDTechEx states that “increasing the max rpm from 10,000rpm to 20,000 rpm increased power density by 69%”, with a further 41% gain at 30,000 rpm.
However, challenges remain: AC losses, rotor integrity, cooling, gearing, and bearing durability. Solutions such as direct oil cooling, reinforced rotors, and ceramic bearings are emerging, but require trade-offs between performance and cost. With over 140 million EV motors forecast for 2036, high-speed motors are set to play a growing role alongside more moderate-speed designs.
