A flywheel is supported by a rolling-element bearing and is coupled to a motor-generator in a typical arrangement. To reduce friction and energy waste, the flywheel and sometimes the motor–generator are encased in a vacuum chamber. A massive steel flywheel rotates on mechanical bearings in first-generation flywheel

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.
The weapons elevators have a load capacity of 42,000 pounds and must move at 2 feet per second even when the sea is rough. The aircraft elevator has a load capacity of 500,000 pounds and must also be moved at 2 feet per second. The aircraft carrier rudder requires a 500 hp motor running at 3000 rpm with high torque.

Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy ; adding energy to the system correspondingly
