Abstract:
An iron core assembly comprising:a plurality of layers of plate-shaped core segments having end portions, said core segments disposed in planar succession in a planar direction in each of the plurality of layers; and couplers coupling the end portions of the core segments of a first layer of the plurality of layers to the end portions of the core segments of a second layer of the plurality of layers; wherein said core segments of the first layer are laminated to the core segments of the second layer in such a manner that the end portions of the core segments of the first layer are offset from the end portions of adjacent core segments of the second layer which adjoin each other in a laminating direction that is perpendicular to the planar direction, and wherein said core segments are rotatable relative to each other through said couplers so as to form an enclosed configuration, and wherein the couplers each include a protruding element at one end of the core segments and a recessed element at another end of the core segments, wherein one of the protruding elements rotatably engages with one of the recessed elements of an adjacent one of the core segments.
