The role of flywheel energy storage device in aircraft carriers

Are flywheel energy storage systems suitable for commercial applications?

Among the different mechanical energy storage systems, flywheel energy storage systems (FESS) are considered suitable for commercial applications. An FESS, shown in Figure 1, is a spinning mass, composite or steel, secured within a vessel with very low ambient pressure.

What is flywheel energy storage system (fess)?

Flywheel Energy Storage System (FESS) is an electromechanical energy storage system which can exchange electrical power with the electric network. It consists of an electrical machine, back-to-back converter, DC link capacitor and a massive disk.

What stabilizes the Flywheel Energy Storage System?

The stability of the Flywheel Energy Storage System (FESS) is increased by a feedback system monitoring the shaft position. Active magnetic bearing accommodates coils that can adjust the amount of electromagnetic force in the system, thereby reducing vibrations in the rotating mass.
