摘要
The ability of high-temperature superconducting (HTS) bearings to exhibit low rotational loss makes possible high-efficiency flywheel energy storage (FES). In this paper, we discuss the general benefit of high-efficiency FES acid a possible route to develop the I-ITS bearings required to achieve it. We describe a method to characterize superconducting bearings in terms of an effective coeffcient of friction and present an expression for the coefficient that is general For most geometries. We also report a coefficient of friction of 3 x 10(-7) for an 0.32 kg rotor. Initial experiments with a 12 kg rotor are also described.
