Flywheel is usually applied in energy storage systems to maintain the energy in the system as rotational energy. Providing energy at rates higher than the capacity of the energy source. This is done by getting energy in a flywheel over time. Then releasing it quickly at rates that exceed the energy source''s capabilities.
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.
For minimal weight and high energy storage capacity, a flywheel can be fabricated from high-strength steel and designed as a conical disc, thick in the center and thin around the rim.
