A flywheel is a mechanical device that stores kinetic energy and allows for smooth power changes. To turn these massive wheels, a significant amount of power is required. It has a large measurement wheel with spokes, as well as a heavyweight edge attached to it.
Several tradeoffs are considered when designing a flywheel system, and the end results vary greatly depending on the end application requirements. Power flywheels, for example, such as the ABB short-circuit generator, can deliver 4,000 MVA and a short-circuit current of 100 kA rms for short periods of time. On the other hand, flywheel variations, such as a lightweight energy flywheel with a rotor specific energy of 195 Wh/kg, are comparable to Li-ion batteries.
Furthermore, during the power stroke, automotive flywheels store energy and deliver it during the idle stroke. As a result, the flywheel's speed increases when it absorbs energy and decreases when it releases energy. As a result, a flywheel does not maintain a constant speed; rather, it reduces speed fluctuation.
Different materials are used to make automotive flywheels. Small lead flywheels can be found in children's toys. Cast iron flywheels are used in old passenger car steam engines. Flywheels, which are used in automobiles to smooth power transmission, are made of cast or nodular iron, steel, or aluminium. High strength steel or composite flywheels have been proposed for use in vehicle power storage and braking systems.
Increase in adoption of automated manual transmission and growth in penetration of dual clutch transmission and continuous variable transmission (CVT) are the main factors that drive the global automotive flywheel market. Moreover, rise in production and sales of vehicles increases the demand for the adoption of flywheels in many applications. In addition, adoption of duel mass flywheels by various Original Equipment Manufacturer (OEM) to reduce the weight of the engine by developing lightweight components to enhance fuel efficiency is expected to boost the growth of the global automotive flywheel market over the forecast period. However, increase in adoption of electric vehicles restrains the growth of the global market. Furthermore, technological advancements in kinetic energy recovery system and rise in demand for different factors such as comfort, aesthetics & safety, and continuous improvement in technology provide lucrative opportunities for the expansion of the global automotive flywheel market.
