Electric Flywheel Basics. 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 [kgm 2 ], and ω is the angular speed [rad/s].
