Abstract

PURPOSE:To eliminate an iron loss of a wound core by inserting a jig with a special magnetic steel plate wound on the core, externally pressing and heat treating it, and then immersing and curing the pressed resin, thereby increasing the occupying rate of the core and limiting the internal stress of the core. CONSTITUTION:A thin magnetic steel plate 2 produced by a superhigh speed quenching method is wound on a wound core 1, is inserted into a jig 3, the part wound with a coil of the plate 2 is pressed externally and is heat treated. After the heat treatment is completed and cooling is performed, resin is immersed in the pressed state, and the pressing is released after the immersed resin 6 is hardened. The plate 2 is preferably formed of a 6.5%-silicon steel or iron-boron- carbon-silicon amorphous alloy steel plate produced by a superhigh speed quenching method of 150mu or less thick, with hardness (Vickers) higher than 200.
