About Photovoltaic Energy StorageAn efficient flywheel stores as much energy per unit weight as possible. As the flywheel is spun up, increasing its angular velocity, ω, it stores more energy. The limit is set by failure caused by centrifugal loading: if the centrifugal stress exceeds the tensile strength (or fatigue strength), the flywheel flies apart.
About Photovoltaic Energy StorageIn this study, a novel magnetic suspension flywheel battery with a multi-function air gap is proposed. Based on the unique multi-function air gap, the degrees of freedom between the control magnetic circuits can be independent of each other, reducing the coupling effect between degrees of freedom. The proposed flywheel battery system …
