A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration is controlled by the mass and speed of the flywheel.

comprised of an energy storage rotor, a motor-generator system, bearings, power electronics, controls and housing. Conventional flywheel designs have a large diameter energy storage rotor attached to a smaller diameter section which is used as a motor/generator. The cost to build and maintain such a system can be substantial.

Generally, the flywheel rotor is composed of the shaft, hub and rim (Fig. 1). The rim is the main energy storage component. Since the flywheel stores kinetic energy, the energy capacity of a rotor has the relation with its rotating speed and material (eq.1). 1 2 2 EI= ω (1) Where, I is moment of inertial (determined by the material

The housing of the flywheel is a component that is essentially responsible for three main tasks: Interface of the connection between moving parts of the flywheel

A flywheel based energy storage apparatus includes a housing and a hub-less flywheel mounted within the housing. The hub-less flywheel has a mass which is shifted radially outwards from a central axis of the hub-less flywheel thus increasing the energy density of the apparatus. The flywheel includes an outer axially extending

The proposed flywheel system for NASA has a composite rotor and magnetic bearings, capable of storing an excess of 15 MJ and peak power of 4.1 kW, with a net efficiency of 93.7%. Based on the estimates by NASA, replacing space station batteries with flywheels will result in more than US$200 million savings [7,8].

Energy storage systems (ESS) provide a means for improving the efficiency of electrical systems when there are imbalances between supply and demand. Additionally, they are a key element for improving the stability and quality of electrical networks. They add flexibility into the electrical system by mitigating the supply intermittency, recently made worse by
