Fault Tolerance Analysis of Multiphase Ironless PMSM for Flywheel Batteries
2023 IEEE 14th International Symposium on Diagnostics for Electrical Machines, Power Electronics and Drives (SDEMPED), 2023This paper investigates the performances of an Ironless PMSM with two phase faults: open circuit of a phase and short circuit of a phase. The machine was specifically designed for a Flywheel Energy Storage System (FESS) and is reconfigurable as 3-Phase, 6-Phase and 12-Phase.

Feasibility of flywheel batteries for electric powered wheelchairs
Proceedings of the 20th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. Vol.20 Biomedical Engineering Towards the Year 2000 and Beyond (Cat. No.98CH36286), 2002Electric powered wheelchairs typically use chemical batteries as their energy source. While this provides effective mobility, the mass of lead-acid batteries is such that it makes the electric powered wheelchair bulky and difficult to transport. Alternative energy sources may lead to lighter and more flexible electric powered wheelchair designs.

Development and testing of the suspension system for a flywheel battery
Control Engineering Practice, 2001Abstract The purpose of this study is to develop a suspension system for flywheel energy storage, that is, a flywheel battery (FWB), on electrical or hybrid electrical vehicles (EV, HEV). If the FWB is operated on vehicles, the gyrodynamics increases the loads of the rotor support bearing and the occupied space of the FWB.

Stress Analysis of Isotropic Material Flywheel Battery Rotor
Applied Mechanics and Materials, 2014The strength of metal materials is far less than the new composite material, such as carbon fiber. However, the price of the metal material and manufacturing cost are much lower than composite materials, which makes isotropic material much more practical for flywheel rotor.

Research on switch compensation control for maglev flywheel battery
IEEJ Transactions on Electrical and Electronic Engineering, 2018In a maglev flywheel system, an unbalanced interference signal synchronous with the flywheel frequency will be produced because the flywheel rotor is uneven. This signal can reduce system control precision and stability, and make the system produce unbalance force vibration.
