Flywheel energy storage for x‐ray machines
Medical Physics, 1984X‐ray image quality for stop‐motion exposures is greatly affected by the system power capability. High power levels are required for adequate resolution, which often precludes the use of mobile x‐ray systems for stop‐motion exposures. Currently available mobile systems use (1) 90‐V nickel–cadmium batteries capable of 120 A, (2) a power line of 220 V ac,

Superconducting energy storage flywheel—An attractive technology for energy storage
Journal of Shanghai Jiaotong University (Science), 2010Flywheel energy storage (FES) can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. The superconducting energy storage flywheel comprising of magnetic and superconducting bearings is fit for energy storage on account of its high efficiency, long cycle life, wide operating temperature range ...

Topology optimization of energy storage flywheel
Structural and Multidisciplinary Optimization, 2016To increase the energy storage density, one of the critical evaluations of flywheel performance, topology optimization is used to obtain the optimized topology layout of the flywheel rotor geometry. Based on the variable density method, a two-dimensional flywheel rotor topology optimization model is first established and divided into three regions ...
