A steel alloy flywheel with an energy storage capacity of 125 kWh and a composite flywheel with an energy storage capacity of 10 kWh have been successfully developed. Permanent magnet (PM) motors with power of 250–1000 kW were designed, manufactured, and tested in many FES assemblies.
In China, the energy density of alloy steel flywheels, which are more widely used in engineering, is 6–13 Wh/kg, which is only 25–40% of that of composite flywheels, and a thicker protective shell needs to be set, so the flywheel energy storage system is heavier.
