Stored Kinetic Energy vs Flywheel Mass (m)

Vedi formula →

Formula

## Flywheel Rotational Energy A flywheel stores kinetic energy in its rotating mass. ### Formulas **I = 0.5 m R^2** (moment of inertia for a solid disc) **E = 0.5 I omega^2** (rotational kinetic energy) where m is mass, R is outer radius, and omega = 2 pi N / 60 is angular velocity. The usable energy is the difference between energy at maximum and minimum operating speeds.

Esempio Risolto

A 50 kg solid disc flywheel, 200 mm radius, spinning at 3000 RPM.

  1. 01R = 0.2 m
  2. 02I = 0.5 x 50 x 0.04 = 1.0 kg-m^2
  3. 03omega = 2 x pi x 3000 / 60 = 314.16 rad/s
  4. 04E = 0.5 x 1.0 x 314.16^2 = 49,348 J = 49.3 kJ
