STATIONARY ELECTROMAGNETIC INDUCTION APPARATUS

PURPOSE:To make it possible to secure the necessary iron core cross sectional area without impairing the magnetic characteristics of the iron core by a method wherein the iron core cut plates, which are cut off from a band-like magnetic material, are laminated in such a manner that the side edge part of an core out plate and the side edge part of other core cut plate are joined together. CONSTITUTION:Three sheets of a core cut plate 12a are picked out, they are placed on the position shown by the solid line of a leg part, then the three sheets of core cut plates 12c, 13a and 13c are picked out from the cut plate groops 12C, 13A and 13C, and they are placed on the position shown by the solid line of a yoke part 56, leg part 55 and yoke part 57. Then, the three sheets of core cut plates 12b are picked out from a cut plate group 12B, and they are stacked on the core cut plates 12a which are already placed. Subsequently, the three sheets of core cut plates 13b, 12d and 13d are picked out from the cut plate groups 13B, 12D and 13D, and they are placed on the position shown by a dotted line of yoke part or leg parts 55, 56 and 57 stacked on the already placed core cut plates 12c, 13a and 13c. As a result, the prescribed number of core cut plates can be laminated within the prescribed measurements of lamination without deterioration in magnetic characteristics.
