A review of flywheel energy storage systems: state of the art and
The ex-isting energy storage systems use various technologies, including hydro-electricity, batteries, supercapacitors, thermal storage, energy storage flywheels,[2] and others.
Technology: Flywheel Energy Storage
Their main advantage is their immediate response, since the energy does not need to pass any power electronics. However, only a small percentage of the energy stored in them can be accessed, given

Cogging torque optimization of axial flux motor for flywheel energy
Axial flux motors with amorphous alloy stator cores are very suitable for flywheel energy storage systems due to their high efficiency and high power density.
Design and Analysis of a Low Torque Ripple Permanent Magnet
Permanent magnet synchronous machines (PMSMs) are commonly used in FESS due to their high torque and power densities. One of the critical requirements for PMSMs in FESS is low
Flywheel energy storage
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than
Flywheel energy storage cogging torque
Shen et al. proposed an external rotor coreless, bearingless permanent magnet synchronous motor to address the issues of high cogging torque and high core losses at high speeds in flywheel energy
