The magnetic performance, rigidity and mechanical precision of an iron core assembly can be improved. A plurality of plate-shaped core segments are disposed in succession to form a plurality of first and second core members respectively. Edge portions of adjacent core segments of the first and second core members are coupled with each other. The first and second core members are alternately laminated one over another in such a manner that first inter-segment positions each defined between adjacent two first core segments of the first core member are offset from second inter-segment positions each defined between adjacent two second core segments of the second core member in a longitudinal direction of the first and second core members, with those edge portions of the respective first and second core segments which adjoin each other in a laminating direction in which the first and second core members are laminated being overlapped each other. The core segments of the first and second core members are rotated relative to each other through the coupling means so as to form an enclosed or ring-like configuration.

1. 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.
