Abstract
A reactor device is provided with a yoke section incorporating an elliptical wire-wound iron core and an iron-core leg section having wire-wound iron cores stacked one on another. The reactor device may have significantly deteriorated magnetic properties due to an abnormal current caused by a magnetic flux developed in the leg section. The short circuit of the abnormal current is cut by providing a cut portion from the center of the end surface of a wire-wound iron core in the leg section to the outer shape thereof and then insulating the cut portion. Use is made of a fixture jig to maintain the shape of the iron core even after the iron core has been cut, and at a final stage, use is made of a band or tape for maintaining the shape. The band used for maintaining the shape is adapted to prevent a magnetic flux developed in the iron core from making one turn.
