Abstract

PURPOSE: To reduce the amount of iron and copper used for the transformer by forming an iron core in such a manner that the cross-sectional area of the core leg is asymmetric in the shape with the inner corner of the core window and the outer corner opposite thereto properly trimmed.
CONSTITUTION: A proper trimming is made on the inner corner 11a on the window side 13 of the leg 11 of a steel-strip-rolled iron core 1, the outer corner 11b opposite thereto, and inner and outer corners 12a and 12b of a yoke 12. The outer corners 11b and 12b shall be trimmed larger than the inner corners 11a and 12a in such a manner that an equaly bidivided line YY' drawn widthwise at the right angle to the lamination direction passes closer to the core window 13 than the point p equally bidividing the maximum dimension in terms of narrow width as to the shape of the section of the leg and the yoke. Accordingly, it is possible to lessen the circumferential length of the envelope at the end rim thereby reducing the amount of copper wire used and minimizing the volume of the core.
