PURPOSE:To obtain a laminated iron core which has smaller magnetic reluctance at a junction by joining in mutually reverse direction laminated blocks wherein plural amorphous magnetic alloy plates are laid sliding to the longer direction one by one and the angle of the end slope is set at a specific value. CONSTITUTION:The yoke 11 and the leg 12 of a laminated iron core are joined perpendicularly and the laminated iron core for a transformer, etc. is made. In this construction, the yoke 11, e.g., has two laminated blocks 13 laid one upon another and the leg 12 has also two laminated blocks 14 laid one upon another. These blocks 13 and 14 are made laminating plural amorphous magnetic alloy plates 15, both the end surfaces 13a and 14a are shifted to the longer direction and the slope angle theta at the end is made to satisfy tantheta=0.05-0.25. Simultaneously, the end surfaces 13a and 14a are joined to make reverse slopes face to face, the gap between these end surfaces is made smaller and the magnetic reluctance against passing magnetic flux is reduced. |
