A Flywheel System Configured for Electrical Storage rundown time. Standby power loss can be minimized by means of a good bearing system, a low electromagnetic drag MG, and internal vacuum for low aerodynamic drag. Given the electric flywheel does not need a shaft seal, a hermetically sealed casing can minimize the operation of the vacuum pump.
The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to (Equation 1) E = 1 2 I ω 2 [J], where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm2], and ω is the angular speed [rad/s].
