WebOct 10, 2024 · E = 0.5*I*ω 2. = 0.5*0.714*335 2. = 40,000 Joules. If it takes 10mins = 600 seconds to stop then a very rough estimate of the power required to overcome friction and other losses in the flywheel is. 40,000/600 = 67W. In other words it takes <100W to keep the flywheel turning at a constant speed. WebA flywheel energy storage (FES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems that is most appropriate for small- and medium-scale uses and shorter period applications. In an FES system, the surplus electricity is stored in a high rotational velocity disk-shaped flywheel.
