Description

Flywheels are often used to provide continuous power output in systems where the energy source is not continuous. For example, a flywheel is used to smooth fast angular velocity fluctuations of the crankshaft in a reciproing engine. In this case, a crankshaft flywheel stores energy when torque is exerted on it by a firing piston, and returns it to the piston to compress a fresh charge of air and fuel. Another example is the friction motor which powers devices such as toy cars. In unstressed and inexpensive cases, to save on cost, the bulk of the mass of the flywheel is toward the rim of the wheel. Pushing the mass away from the axis of rotation heightens rotational inertia for a given total mass.

Characteristic

1.Smoothing the power output of an energy source. For example, flywheels are used in reciproing engines because the active torque from the individual pistons is intermittent.
2.Energy storage systems
3.Delivering energy at rates beyond the ability of an energy source. This is achieved by collecting energy in a flywheel over time and then releasing it quickly, at rates that exceed the abilities of the energy source.
4.Controlling the orientation of a mechanical system, gyroscope and reaction wheel
5.The lumped moments of inertia of spokes, hub and shaft may be estimated as a percentage of the flywheel's moment of inertia.
