Flywheel energy storage device
WebA flywheel energy storage device has a central shaft, a flywheel having a flywheel rotor supported by and mounted for rotation around said shaft, and a motor/generator having a stator and a rotor. The rotor is formed integrally with the flywheel rotor. The stator has an outer cylinder that is cooled by a liquid flowing in contact with its cylindrical surface.

WebAmong energy storage devices, superconducting magnetic energy storage (SMES) is one of the most efficient energy storages with 98% efficiency. However, unlike flywheel storage, energy storage time in the SMES is possible for a short time. Another problem with this storage that can be mentioned is that it is expensive in terms of economics.
