ABSTRACT:
A flywheel device in which a rotating body is rotatably supported within a casing, the rotating body comprising a rotor rotated at a high speed and a flywheel rotated integrally with the rotor to accumulate rotating energies capable of being converted into electric energies at a time of a power failure. A protective ring is provided beween the outer surface of the rotating body and the inner circumferential wall of the casing. Upon the occurrence of an abnormally high speed of the rotating body, the rotor of the rotating body engages the protective ring. The protective ring is free of fixed engagement with the casing so that when engaged by the rotor the weight of the protective ring is added to that of the rotating body to act as a braking force.
