板であるので、そのスペーサの孔に鋼棒を挿入する際に
、スペーサは損傷し易いから組立てが困難である。The medium is a flexible disk with a thickness of 10 to 100 μm, and since holes are machined into it into which steel rods for lamination are inserted, the dimensional accuracy of these holes is low, and when inserting the steel rods, The holes and the medium may become deformed. For this reason, the laminated media cannot maintain concentricity, resulting in a problem that the media rotates in a vibrating state. Further, since the spacer is a membranous disc made of metal or plastic and having a diameter of 10 to 100 μm, the spacer is easily damaged when a steel rod is inserted into the hole of the spacer, making assembly difficult.
