...Hongchang Wang; Shuyun Jiang; Zupei Shen Active magnetic bearings and superconducting magnetic bearings were used on a high-speed flywheel energy storage system; however, their wide industrial acceptance is still a challenging task because of the complexity in designing the elaborate active control...

... ball and races during the touchdown. The thermal growths of bearing components are predicted using a one-dimensional thermal model, and the resulting expansions contribute to the calculation for the Hertzian contact loads. Numerical simulations for an energy-storage flywheel module reveal that a high...
