PURPOSE:To improve rigidity and magnetic characteristics of a core by providing amorphous magnetic alloy thin plates in the inside of the wound core in such a manner that a pair of U-shaped reinforcing plates butt with each other at the leg side of the wound core to couple one portion of the reinforcing plates with a core clamp on the side of a yoke member. CONSTITUTION:A pair of U-shaped reinforcing plates 6 are set in an opposing relation with each other on the periphery of a winding center during winding process of a wound core 2. Amorphous magnetic alloy thin belts are wound spirally up to the fixed size on the periphery to form the wound core 2. At this time, both ends of the reinforcing plate 6 are completely butted with each other. The reinforcing plate 6 is constructed so as to be bent or welded at a portion corresponding to a yoke member of the core in the laminationwise direction of the laminated core. A non-magnetic plate having a hole is welded with a portion of a brim of the reinforcing plate. One portion of each reinforcing plate 6 contacted with the side of the yoke member of the wound core 2 is connected with upper and loweer clamps 7 and 8 fixed on the side of the yoke member of the wound core 2 via a clamp member 9 respectively to improve rigidity and magnetic characteristics of the wound core 2. |
