Abstract

PURPOSE: To obtain stably characteristic iron core without less dispersion in quality and to make easier the manufacture of stamp-out iron core by laminating and adhering a magnetic plate having a high bending strength on a noncrystal magnetic alloy plate.
CONSTITUTION: A plural number of noncrystal magnetic alloy plates are laminated and adhered with the adhesive 3, and above these plates, the silicon steel plate 2 having a strong bending strength higher than the noncrystal magnetic alloy plate is adhered with the adhesive 3 to form the laminated plate 4. The laminated plate 4 is stamped out to the E-shape A and I-shape B to obtain the iron core of the transformer. Thus, in contrast to the conventional case in which only the noncrystal magnetic alloy plate 1 is stamped out to form the iron core, the bending of the end portion due to a force applied to the magnetic plate can be avoided at the time of the stamp-out processing, and thus the dimensional accuracy can also be raised. In addition, the butt joining of the E-shaped iron core and the I-shaped iron core can be completely performed without causing aperture and void, resulting in the enhancement of the characteristics of iron core
