Expert Insight: The Pivotal Role of Bearings in Electric Vehicles (EVs)

1.Article Highlights
I. High-Speed Performance

EV motors often operate at speeds between 15,000 and 20,000 RPM. This demands exceptional centrifugal force tolerance, superior lubricant retention, and precise heat management from the bearings.
II. Combating Electrical Erosion
Induced currents from high-frequency inverters can lead to electrical erosion (EDM effect) within the bearing. Utilizing ceramic ball bearings (hybrid bearings) or insulated coatings is the industry standard for preventing such damage.
III. Range Extension and NVH Performance
Low-friction torque technology directly reduces energy loss, thereby extending the driving range. Furthermore, precision manufacturing significantly lowers operational noise, meeting the stringent NVH requirements of EVs.
