Fly wheel density
Webdesign of high energy density flywheels to operate at the maximum rotational speed. Although the exact relationship depends on the flywheel design, in general, the maximum rotational velocity and specific energy of a flywheel are proportional to the allowable working strength divided by the density of the rotor material: Figure 1. WebOct 5, 2011 · Basic concepts. Flywheels are nothing more than discs or cylinders that spin around a fixed axis. The amount of energy a flywheel can store is proportional to its mass ( m ), the square of the speed at which it spins ( w) and the square if its radius ( r ). The general equation for a solid disc is of this form: E = 1/4 · m · r2 ...
