Abstract

PURPOSE: To manufacture with high efficiency a transformer with use of an iron core keeping its high magnetic characteristics by cutting a circular body around which amorphous magnetic alloy thin bands are wound into a plurality of iron core blocks, and rendering them to re- joining, formation of a rectangular iron core, annealing, winding of a wire thereon, and spacer insertion for each block, etc.
CONSTITUTION: A circularly-wound iron core 3 is formed by inserting a spacer 4 each time an amorphous magnetic alloy thin band 2 is wound on a core predetermined times, which core 3 is then cut radially thereof along a cut surface A into iron core blocks 3aW3d. Longitudinal laminated surfaces 3al, 3a2 for example of each of the blocks 3aW3d are slanted stepwise, and those blocks 3aW3d are wound successively on an iron core such that the spacer 4 covers a connection portion between those surfaces. The circularly wound iron core is made to be a rectangularly wound iron core using a rectangular iron core. Annealing of the resulting rectangularly wound iron core assures a high magnetic characteristic of the iron core without causing any distortion of the core. In succession, an aperture of the iron core 9 is opened through which aperture a wire 10 is wound around the core together with a magnetic spacer 11 inserted into the aperture. Hereby, a transformer with the iron core keeping high magnetic characteristics can be manufactured effectively without causing disturbance of magnetic lines around the joining portions and without insertion of a spacer for each sheet of alloy thin band.
