⚡ Flywheel Energy Storage Calculator 🔄

How to use this calculator:

1. Select the shape of your flywheel (Solid Disk, Thin Ring, Hollow Cylinder, or Custom)
2. Enter the mass of the flywheel in kilograms
3. Enter the outer radius (and inner radius if applicable)
4. Set the rotational speed in RPM
5. Optionally set minimum RPM for discharge time calculation
6. Enter load power to calculate discharge time
7. View results and charts

Key Concepts:

Kinetic Energy (E): The energy stored in the rotating flywheel, calculated as E = ½ × I × ω²

Moment of Inertia (I): A measure of resistance to angular acceleration, depends on mass distribution

Angular Velocity (ω): The rotational speed in radians per second, converted from RPM

Discharge Time: How long the flywheel can deliver power before reaching minimum RPM
