Function of Flywheel. A flywheel is a heavy wheel attached to a rotating shaft so as to smooth out the delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use. Flywheels are found in almost all types of automobiles

The flywheel is connected, via a fixed ratio transmission, to an induction motor, M3EH 160D 4, with the nominal power of 136.5 kW and maximum rotational speed of 6500 rpm, capable of rotating the flywheel up to 40,000 rpm.

High power UPS system. A 50 MW/650 MJ storage, based on 25 industry established flywheels, was investigated in 2001.
