  • Large capacity hollow-type flywheel energy storage device
    Patent number: 8134264
    Abstract: Disclosed is a large capacity hollow-type flywheel energy storage device. The energy storage device includes a hollow shaft, a vacuum chamber receiving the hollow shaft, a flywheel having a predetermined weight and disposed at an inner edge of the vacuum chamber, and a hub connecting the flywheel to the hollow shaft and disposed in the vacuum chamber to be rotatable together with the flywheel. A superconductive bearing and an electromagnet bearing are disposed inside and outside the hollow shaft, respectively, such that magnetic forces thereof can be shielded from each other. Thus, magnetic interference between the superconductive bearing and the electromagnet bearing is shielded by the magnet shield interposed therebetween, thereby preventing rotation loss by stabilizing a structural mechanism during rotation while improving design adaptability.
