storage systems (FESS) are summarized, showing the potential of axial-flux permanent-magnet (AFPM) machines in such applications. Design examples of high-speed AFPM machines a e pro ided and
The ex-isting energy storage systems use various technologies, including hydro-electricity, batteries, supercapacitors, thermal storage, energy storage flywheels,[2] and others.
Flywheel energy storage stores electrical energy in the form of mechanical energy in a high-speed rotating rotor. The core technology is the rotor material, support bearing, and
Flywheel energy storage is defined as a method for storing electricity in the form of kinetic energy by spinning a flywheel at high speeds, which is facilitated by magnetic levitation in an evacuated chamber.
The energy storage capacity of an FESS can be enhanced by increasing the speed and size of the flywheel rotor. However, a significant

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10, up to 10, cycles of use), high specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 133 kWh. Rapid charging of
In this application, the speed of the flywheel varies only slightly between pulses and relatively little energy is stored in the rotor. For example, the massive rotor of the Corliss Centennial Engine stored
Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm.
The flywheel was brought to full speed (9,000 rotations per minute [rpm]) which is equivalent to the maximum energy storage capacity of 32kWh for the M32 flywheel.
