A recent innovation in electrical energy storage is the use of flywheel energy storage, also called flywheel power storage. A typical system consists of a massive flywheel disc suspended by magnetic bearings inside a vacuum chamber to reduce friction, connected to a combination electric motor/electric generator. The wheels are generally made of high-tensile-strength fibers (such as carbon fibers) embedded in epoxy resins, or some other high-strength composite material. The system stores power by driving the motor to increase the speed of the sp ....etc

With the ever-increasing demand for energy, we have to focus our attention on greener alternatives. The main problems with non-conventional energy sources are that they need storage. Flywheel batteries seem to solve this problem to a great extend. Flywheel energy storage systems are non-polluting; need no replacement and little maintenance. The basic working of flywheel batteries and their applications are discussed in brief. Flywheel batteries stores energy as rotational kinetic energy of the flywheel and this energy can be retrieved either th ....etc

Flywheel energy storage

INTRODUCTION
Flywheel energy storage systems store kinetic energy (i.e. energy produced by motion) by constantly spinning a compact rotor in a low-friction environment. When short-term back-up power is required (i.e. when utility power fluctuates or is lost), the rotor's inertia allows it to continue spinning and the resulting kinetic energy is converted to electricity.
Active Power's CleanSource® Flywheel Technology, as shown below, integrates the function of a motor, flywheel rotor and ....etc

Aerospace Flywheel Development

) INTRODUCTION
Presently, energy storage on the Space Station and satellites is accomplished using chemical batteries; most commonly nickel hydrogen or nickel cadmium. A flywheel energy storage system is an alternative technology that is being considered for future space missions. Flywheels offer the advantage of a longer lifetime, higher efficiency and a greater depth of discharge than batteries. A flywheel energy storage system is being considered as a replacement for the tradition ....etc

The dual mass flywheel, or DMF, eliminates excessive transmission gear rattle, reduces gear change/shift effort, and increases fuel economy. There are two basic types of Dual Mass Flywheels. The first is made up of a primary and secondary flywheel with a series of torsion springs and cushions. There is a friction ring located between the inner and outer flywheel that allows the inner and outer flywheel to slip. This feature is designed to alleviate any damage to the transmission when torque loads exceed the vehicle rating of the transmission. T ....etc
