Abstract
PURPOSE: To obtain a iron core cross section of good space factor, by varying the width of a steel band, and winding this steel band into an iron core of cross section nearly circular.
CONSTITUTION: In shaping steel band S1, its width d is continuously varied over a length l, following the locus of an ellipse with major axis l and minor axis d. By this, winding iron core RC1 of nearly circular cross section is obtained.
