What is a flywheel energy storage calculator?

Our flywheel energy storage calculator allows you to calculate the capacity of an interesting type of battery!

How do you calculate kinetic energy stored in a flywheel?

Consider a flywheel with a certain mass and radius, spinning at a specified angular velocity. By inputting these values into the calculator, you receive the total kinetic energy stored. For instance, if a flywheel with a mass of 20 kg and a radius of 0.5 m spins at 3000 RPM, the calculator will provide the energy stored in Joules.

How is energy stored mechanically in a flywheel?

Energy is stored mechanically in a flywheel as kinetic energy. Kinetic energy in a flywheel can be expressed as I = moment of inertia (kg m2, lb ft2) Moment of inertia quantifies the rotational inertia of a rigid body and can be expressed as k = inertial constant - depends on the shape of the flywheel

How does a flywheel work?

They do so by accelerating a rotor to a high speed and maintaining the energy in the system as rotational energy. When energy is needed from the system, the flywheel's rotational speed is reduced to release the stored energy, typically to perform work or balance energy demand.

What is kinetic energy in a flywheel?

A flywheel can be used to smooth energy fluctuations and make the energy flow intermittent operating machine more uniform. Flywheels are used in most combustion piston engines. Energy is stored mechanically in a flywheel as kinetic energy. Kinetic energy in a flywheel can be expressed as I = moment of inertia (kg m2, lb ft2)

How much energy does a flywheel store?

Assuming a 28 in wheel with mass m = 2.87 lb, the energy stored is 3.25 J. To find this result: I = 2.87 × 1 × 14² = 3.9 lb·ft². How does a flywheel store energy? A flywheel can store energy thanks to the conservation of angular momentum.
