Introduction. A flywheel comprises a rotating mass that stores kinetic energy. When charging, a torque applied in the direction of rotation accelerates the rotor, increasing its speed and stored energy. When discharging, a braking torque decelerates the rotor, extracting energy while performing useful work.
Revterra stores energy in the motion of a flywheel. Electric energy is converted into kinetic energy by a spinning rotor. When needed, that kinetic energy is converted back to electricity. Revterra''s innovative approach leverages passively stable magnetic bearings and low-cost steel alloys to improve efficiency and reduce cost.

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.
