A device and method for efficiently rotating a rotating body in a layer structure consisting of a plurality of rotating plates arranged in layers and intends to provide a device for and method of rotation capable of efficiently converting sequentially input rotative driving power into the rotational energy of the whole of the rotating body in a layer structure. A rotating device of this invention comprises a layered rotating body composed of a plurality of rotating plates (11 to 17) arranged in layers with distances therebetween and their rotating axes (3) aligned, in which, on each of said layered rotating plates (11 to 17) of the rotating body, groups of magnetic poles (31 to 37) are provided on the respective surfaces of the plates facing neighboring layers, said groups of magnetic poles (31 to 37) are made equal in polarity to those (31 to 37) on the opposing rotating plate (11 to 17) surfaces in the neighboring layers, and each magnetic pole in said groups (31 to 37) is arranged so as to be alternately opposite in the rotational direction to each one in groups (31 to 37) on opposing plates (11 to 17) in neighboring layers. Such a rotating device as above can be used as for example, a flywheel energy storage system when the rotating plates are used as flywheel disks and rotated at high speed to store rotational energy of the flywheel disks. <IMAGE> |
