The flywheel housing is solid and sits outside of the flywheel. The flywheel is the part of the engine that rotates and delivers power to the alternator. 2. Springs. The flywheel is consists of two-phase bent springs in parallel. The outer arc is adjusted to raise the spring when the engine is operating.
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.
As you can see, both flywheels and supercapacitors have their pros and cons. Flywheels have a higher energy density, and supercapacitors have higher power density. Ultimately, the choice between the two will depend on the specific application and requirements. Whatever you choose, know that you''re making a step towards a more
