Xiaomi breaks through 35,000-rpm motor technology! Newly created laser wound rotor

At the Xiaomi Auto Technology Conference on December 28, the first point Lei Jun talked about was the heart of electric vehicles—the motor.
To this end, Xiaomi has created a variety of super motors (HyperEngine).
In addition to the 21,000-rpm Xiaomi super motor V6/V6s that has been mass-produced and will be on the market for the first time, and the 27,200-rpm Xiaomi super motor V8s that has been mass-produced and will be on the market in 2025, Xiaomi is also pre-researching more advanced technologies.
Lei Jun revealed that Xiaomi Lab has completed the technical pre-research of the 35,000-rpm motor and adopted a new carbon fiber Aurora winding rotor process.
This technology uses laser in-situ solidification technology to realize carbon fiber winding rotors, thereby achieving higher yields, better pre-tightening force, and higher speeds.
Lei Jun emphasized that Xiaomi will continue to invest in motor research and development and strive to become an industry leader.
