1. Cast iron flywheel: After casting, it must go through more than two times of processing, which takes time, and it will cause material waste when casting or processing, and its cost is high.

2, aluminum alloy flywheel: aluminum alloy unit price is higher, so the cost is higher

3. Cement and concrete flywheel: This type of flywheel is made by pouring cement or concrete into a mold to solidify it. However, the flywheel formed by cement or concrete is easily broken due to the problem of the material itself. Therefore, it must be in the outer ring. The interior of the flywheel center is filled with a large amount of cement or concrete, which causes waste of materials. Moreover, the function of cement and concrete flywheels is not easy to change, and it is not environmentally friendly.

In addition to the above, the traditional flywheel design does not consider the optimization of the rotational inertia, in addition to wasting material costs, it also fails to achieve the sporting effect. Moreover, when the traditional flywheel is designed, The diversified demand for power generation or damping is not considered. When there is demand, it is necessary to increase the cost of the design, resulting in a situation of half the effort.

The main object of the present invention is to provide a combined flywheel structure of multifunctional design.
