A flywheel is a rotating mechanical device that is used to store rotational energy that can be called up instantaneously. At the most basic level, a flywheel contains a spinning mass in its center that is driven by a motor – and when energy is needed, the spinning force drives a device similar to a turbine to produce electricity, slowing the rate of rotation.
Electric Flywheel Basics. The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to. E = 1 2 I ω 2 [ J], (Equation 1) where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2 ], and ω is the angular speed [rad/s].
A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration is controlled by the mass and speed of the flywheel.
Electrical flywheels are kept spinning at a desired state of charge, and a more useful measure of performance is standby power loss, as opposed to rundown

A flywheel is a mechanical device which stores energy in the form of rotational momentum. Torque can be applied to a flywheel to cause it to spin, increasing its rotational momentum.

There are a few key reasons. First, flywheels are quick to adapt to changes in power demand, so they can supply power when it is most needed. This is particularly crucial for renewable energy sources because they can be unpredictable. Second, unlike batteries, flywheels have a long lifespan and don''t lose their effectiveness over time.
A flywheel is a mechanical device that uses the conservation of angular momentum to store rotational energy, a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed.

1 Answer. A flywheel diode, also known as a freewheeling diode or a snubber diode, is a diode used to protect electronic circuits from voltage spikes or "back electromotive force" (EMF) that can occur when an inductive load is suddenly switched off. Inductive loads include devices like motors, solenoids, transformers, or relays.
A flywheel energy storage system can be described as a mechanical battery, in that it does not create electricity, it simply converts and stores the energy as kinetic energy until it is needed.
