A rotating device and a rotating method for efficiently rotating a layered rotating body in a layer structure comprises a plurality of rotating plates arranged in layers. A device and a method for the rotation of the layered rotating body are provided capable of efficiently converting sequentially entered rotative driving power into the rotational energy of the whole of the layered rotating body of a layer structure. The rotating device of this invention comprises a layered rotating body in a layer structure, having a plurality of rotating plates (11 to 17) arranged in layers in a spaced relationship equally apart from each other and their rotating axes (3) aligned coaxially, in which, on each of said layered rotating plates (11 to 17) of the layered rotating body, groups of magnetic poles (31 to 37) are provided on the surfaces of the respective rotating plates facing neighboring layers, said groups of the magnetic poles (31 to 37) are made equal in polarity to those (31 to 37) on the respective rotating plates (11 to 17) facing the opposite neighboring layers, and each magnetic pole in said groups of the magnetic poles (31 to 37) is arranged so as to be alternately opposite in the rotational direction to each other in the groups of the magnetic poles (31 to 37) in neighboring layers. Such a rotating device as described hereinabove can be employed as, for example, a flywheel energy storage system when the rotating plates are utilized as flywheel disks and rotated at a high speed to store rotational energy of the flywheel disks.
