Composite materials are widely used to build high-performance flywheels due to their high material strength and low mass density. The high degrees of freedom in material selection, design, and manufacturing techniques lead to a variety of rotor structures. This paper presents the characteristics of different composite rotors and the critical considerations in terms of designing, manufacturing, and testing them. The introduction starts with the limitations of a single filament-wound composite rim. Then, various rotor structures are presented as well as the critical issues regarding the composite rim design, rim-shaft connection, and rotor failure in order to make safe design recommendations. The aim is to summarize the current techniques and provide references for further developments.

“…A novel steel rotor flywheel was proposed by Tortella et al [ 15 ] with optimizing permanent magnets and excitation coils, which was for a hybrid suspension system. High rotation speed and high energy density in a rotor system were chosen as objects by Hiroshima et al [ 16 ] Then, authors took numerical calculations to design annular disks made of three‐dimensionally carbon‐fiber‐reinforced composites. Gowayed et al [ 17 ] applied an approach with parametric finite element analysis to take structural optimization of MDC flywheels based on a sequential quadratic programming method.…”

With the development of CFRP materials and co‐cured structure, CFRP/Al hybrid co‐cured materials have been widely used for high‐speed energy storage flywheels. Therefore, it has become a hot research topic, which is to design a CFRP/Al hybrid co‐cured flywheel with a reasonable structure. In this paper, a particle swarm optimization algorithm is presented for improving the energy storage density to optimize the structure of the CFRP/Al hybrid co‐cured high‐speed flywheel. First, the stress and structural analysis of the flywheel are carried out based on energy storage. The inner‐radius‐to‐outer‐radius λ and the radial wall thickness h are chosen as the objective function because the λ and h are the factors which influence the energy storage density of the flywheel. Based the Tsai‐Hill criterion, the assembly interference t is the constraint condition which is the factor to meet the stress of design requirements. Then, the mathematical model of the flywheel is established by the objective function and the restriction with the particle swarm optimization algorithm (PSO). Finally, a specific CFRP/Al hybrid co‐cured flywheel is presented for the structural optimization with PSO by improving the energy storage density. In addition, the optimized flywheel is carried out to examine the static and dynamic requirements by the finite element method. The results indicate the PSO can be effectively used to optimize the structure of the CFRP/Al hybrid co‐cured high‐speed flywheel.

“…In order to accumulate maximum of energy at high speed, if the flywheel diameter is less than 50 cm it has to operate at speeds above 15000 rpm in a low friction environment like vacuum in order to minimize friction [10]. Composite materials are the first choice in order to withstand the high centrifugal forces [11]- [13]. Hydrodynamic bearings are also used in such systems [14].…”
