An electric motor coil element embodying this invention is manufactured by the steps of closely winding a single wire about a columnar bobbin to provide a cylindrical original winding having a diameter d, setting a 2n number of equal division points on the periphery of said cylindrical original winding to divide said periphery into equal parts, specifying the bending lines which pass through the equal division points at prescribed angles phi 1 and phi 2 to the reference lines which are set in parallel with the axis of said cylindrical original winding and pass through said equal division points, and bending the segments of said original cylindrical winding is such a manner that said bending lines project alternately inward and outward along the periphery of an imaginary block form having a prescribed shape. |
