Abstract:
1. A laminated core for an electromagnetic device, comprising a plurality of generally identical blocks, wherein each block includes: a laminated body that includes a plurality of amorphous alloy plates, which are stacked one after another in a stacking direction such that each adjacent two of the plurality of amorphous alloy plates directly contact with each other; first and second clamping plates that contact opposed first and second end surfaces, respectively, of the laminated body in the stacking direction, wherein a thickness of each of the first and second clamping plates in the stacking direction is larger than that of each of the plurality of amorphous alloy plates; and at least one holding member, which contacts with the first and second clamping plates and maintains a predetermined space between the first and second clamping plates while the laminated body is clamped between the first and second clamping plates, wherein: each holding member is spaced from the laminated body; and the laminated body, the first and second clamping plates and the at least one holding member are integrated together in each block.
