What is a flywheel system?

Flywheel systems are composed of various materials including those with steel flywheel rotors and resin/glass or resin/carbon-fiber composite rotors. Flywheels store rotational kinetic energy in the form of a spinning cylinder or disc, then use this stored kinetic energy to regenerate electricity at a later time.

How does a flywheel energy unit work?

D. Power Electronics The flywheel energy unit produces variable frequency AC current. To reliably operate the system, power electronics devices must be installed in order to keep the frequency constant so that it can be connected to the grid. Power converters for energy storage systems are based on SCR, GTO or IGBT switches.

How does a flywheel work?
