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 ...

Comparison of energy storage in flywheels and SMES
Physica C: Superconductivity, 2001Abstract Generally valid expressions and scaling rules are derived, which relate the stored magnetic energy in a SMES and flywheel to the required minimum amount of superconducting, structural and stabilizing material. Results are widely independent of details like magnet type and dimensions, the only specific design variable is a magnetic coil ...
