Abstract
PURPOSE:To manufacture the thickness dimension of a laminated core with a high accuracy by manufacturing only plural prescribed number of the continuously blanked plural shaped magnetic thin plates, punching the plate to remove the prescribed part thereafter and laminating them continuously. CONSTITUTION:From a roll 1b, a high permeability magnetic sheet hoop material 1 is pull out core materials 5 and 5' of patterns P1-P12 and P0 are continuously blanked and the core materials 5 and 5' are continuously housed to a housing jig 7. The core material 5 is of a prescribed shape, and the core 5' is of the shape to remove the part of A and A as shown in the figure. Next, a laser light 8 is projected through a lens 9 to the continuous lamination of the core materials 5 and 5' and laser beam welding is performed. Thus, a bulk sample is welded at a part 11, for the core material 5', the welded part is removed A and A, and therefore, only it is not welded. Consequently, the core material 5' becomes a separating plate, a laminating core 10 is obtained and the core material 5' is thrown away. After the laminating core 10 is magnetically annealed in the hydrogen gas of 1,100 deg.C, an epoxy resin is vacuum- impregnated and hardened and the laminating layer 10 is obtained.
