<P>PROBLEM TO BE SOLVED: To form a vertically wound coil which is formed by winding a square-shaped conducting wire so that a cylinder shape consisting of four bent portions and straight portions in alternately serial manner in a peripheral direction and is wound on a coil winding portion having a cross-section outer shape of a substantially rectangular quadrilateral, so that the radius of curve of a bent portion is set smaller to contribute to a space factor while eliminating the necessity of unwanted processing of the square-shaped conducting wire. <P>SOLUTION: A plurality of square-shaped conducting wires 34, 35 are wound so that the external periphery of internal square-shaped conducting wires 34 contacts the internal periphery of the external square-shaped conducting wires 35, thereby forming the vertically wound coil. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
