An elliptical yoke formed by deformation heat treatment and a double concentric stratified annular body made of a non-oriented silicon steel strip are pressed from the peripheral direction and deformation heat treated to form an ellipse having a shorter length and the same width than the ellipse of the yoke. It consists of a stacked body of iron core legs formed by stacking a plurality of horseshoe-shaped iron core legs obtained by forming a body and dividing it into two in the longitudinal direction, and wrapping a winding around the core legs, and two ellipsoids. Two core leg stacks are arranged upright between the horseshoe-shaped core legs so that the split surfaces of the horseshoe-shaped core legs face each other, and the annular body surfaces of the core legs abut against the annular body surfaces of the yoke. It was thought that a predetermined magnetic resistance could be obtained by connecting the two, and based on this knowledge, the planar butting type reactor of the present invention was invented.

られる。 That is, FIG. 7A shows the case of the conventional annular stratified core leg, and FIG. 7B shows the case of the horseshoe-shaped core leg of the present invention, but as is clear from these figures, they are the same. Considering the cross-sectional area,
The length from the tightening bolt penetration part P to the cut surface is 50 in the case of an annular shape, and 39.3 in the case of a horseshoe shape. When you combine this with an oval yoke,
As shown in FIG. 7C, the length L of the yoke is shorter than the legs of the annular cylinder, and therefore, the effect of reducing the weight and shortening the magnetic path length can be observed.
