【Abstract】 Flywheel energy storage(FES) is an advanced energy storage technology that has bright prospect for application and has been used practically. High-speed bearing technology is one of the key factors that restricts the efficiency and life of FES system. The merit and demerit of mechanical bearing, permanent magnetic bearing, active magnetic bearing and superconducting magnetic bearing are analyzed and compared. The recent cases of R&D of bearing technology in FES system at home and abroad are reviewed.更多还原
