PURPOSE:To easily obtain a laminated iron core using amorphous magnetic alloy thin plate by forming a frame like a picture frame by bending at a right angle the areas corresponding to the corners of iron core of a belt shaped amorphous magnetic alloy thin plate and continuously laminating such frames. CONSTITUTION:The iron core blocks 11-14 are formed by continuously bending the four corners of amorphous magnetic alloy thin plate 15 with a press. Next, distortion is eliminated by executing annealing process to the blocks 11-14. Since the iron core as a whole can be divided into the blocks 11-14 in the laminating direction and can be annealed, distribution of temperature of iron core as a whole can be uniformed during the annealing process. The blocks 11- 14 are impregnated with resin such as epoxy resin and are integrated. Moreover, the blocks 11-14 are combined and tightened by tightening bolts. Thereby, it is no longer necessary to cut the hard and brittle thin plates 15 with a cutter and the iron core blocks can be formed easily and continuously during the bending process. |
