4.1 Pulley. A pulley is a wheel on an axel or shaft that is designed to support movement and change of direction of a taut cable. The supporting shells are called blocks. A pulley may also be called a sheave or drum and may have a groove or grooves between two flanges around its circumference.
Flywheel Energy Storage
When energy is required, the motor functions as a generator, because the flywheel transfers rotational energy to it. This is converted back into electrical energy, thus completing the cycle. As the flywheel spins faster, it experiences greater force and thus stores more energy. Flywheels are thus showing immense promise in the field of energy ...
Flywheels
The kinetic energy stored in flywheels - the moment of inertia. 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.

Flywheel Power Calculator
It provides a convenient way to determine the power output of a rotating flywheel. The formula used by the Flywheel Power Calculator is: Flywheel Power = (0.5 * Moment of Inertia * Angular Velocity^2) / Time. In this formula, the Moment of Inertia represents the rotational mass of the flywheel, measured in kilogram-meter squared (kg-m^2).

Aerodynamic drag and bearing friction are the main sources of standby losses in the flywheel rotor part of a flywheel energy storage system (FESS). Although these losses are typically small in a ...
Flywheel energy storage
A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.
