A Flywheel Energy Storage System with Active Magnetic Bearings

Abstract. A flywheel energy storage system (FESS) uses a high speed spinning mass (rotor) to store kinetic energy. The energy is input or output by a dual-direction motor/generator. To maintain it in a high efficiency, the flywheel works within a vacuum chamber. Active magnetic bearings (AMB) utilize magnetic force to support …

How do flywheels store energy?

An easy-to-understand explanation of how flywheels can be used for energy storage, as regenerative brakes, and for smoothing the power to a machine. The physics of flywheels Things moving in a straight line have momentum (a kind of "power" of motion) and kinetic energy (energy of motion) because they have mass (how much …

The ENERGY WHEEL

ncept of energy. Attributed to Haddon (1973), the energy theory is based on the observation that all injuries are the result of some undesirable contact be-tween a person and one or more s. urces of energy. In accordance with this theory, a hazard is more precisely defined as a source of energy that could cause injury,

Flywheel energy storage

This high-speed FESS stores 2.8 kWh energy, and can keep a 100-W light on for 24 hours. Some FESS design considerations such as cooling system, vacuum pump, and housing will be simplified since the ISS is situated in a vacuum space. In addition to storing energy, the flywheel in the ISS can be used in navigation.
