Flywheel energy storage
A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.

How the Flywheel Works. The flywheel energy storage system works like a dynamic battery that stores energy by spinning a mass around an axis. Electrical input spins the flywheel hub up to a high speed and a standby charge keeps the unit spinning until its called upon to release . its energy. The energy is proportional to its mass and speed

While modern flywheels operate at a surface speed of 500 m s –1 or more, flywheels in stationary steam engines seldom ran at surface speed exceeding 20 m s –1 [12] nsequently, since kinetic energy scales with the square of speed, a 50 t (where t is a metric tonne) flywheel from the industrial age would store just 5 kW h.

Generator flywheel and diesel were on one axis with a coupling towards the diesel. The flywheel was constructed as an engine around that axis, so the stator is the axis at 1500 rpm and the flywheel turns around at max. 4400 rpm. If energy needs to be provided, the outer rotor is slowed down by a brake in that axis, so the energy is transferred.
