The flywheel energy storage operating principle has many parallels with conventional battery-based energy storage. The flywheel goes through three stages during an operational cycle, like all types of energy storage systems: The flywheel speeds up: this is the charging process. Charging is interrupted once the flywheel reaches the maximum ...
The minimum speed of the flywheel is typically half its full speed, the storage energy is be given by ½ (1 2-0.5 2) I f w f 2 where I f is the rotor moment of inertia in kgm 2 and the w f maximum rotational speed in rad/s. The power level is controlled by the size of the M/G, so this is independent of the rotor.
