Formula

The primary formula used in the Flywheel Energy Storage Calculator is:

Energy (E) = 0.5 × I × ω²

Where:

• E = Energy stored (in joules)
• I = Moment of inertia (kg·m²)
• ω = Angular velocity (in radians/second)

This formula allows you to derive the stored energy based on both the physical characteristics of the flywheel and its operational parameters.

Example Calculation

To illustrate how the calculator works, let’s consider a practical example:

If we have a flywheel with a moment of inertia of 5 kg·m², and it rotates at an angular velocity of 100 radians/second, we can plug these values into the formula:

E = 0.5 × 5 kg·m² × (100 rad/s)²

Calculating further gives:

E = 0.5 × 5 × 10000 = 25000 Joules

This means our flywheel can store 25,000 joules of energy, which is a substantial amount for fast energy discharge needs.
