Abstract

PURPOSE:To ameliorate the insulating property of winding, and to increase a space factor by stacking and winding wire rods with square sections, the length of each side thereof is equal, in a stone wall shape. CONSTITUTION:A pair of molding rollers to which V-shaped grooves having an angle of 45 deg. are mounted on the midway of a winding machine, and a wire blank with a circular section is molded to a regular square section through the molding rollers. Circular arc sections 28 with a fixed radius are shaped to the corner sections of the wire rod at that time. The wire rod molded is wound successively on a coil frame body 7, both ends thereof have flanges 30 and to which a corrugated winding guide groove 11 with a pitch conformed to the size of a diagonal line of the wire rod 27 molded on the surface of a winding core section 29 is formed, and the rod is stacked and wound in the stone wall shape that is arranged in a lattice form that the diagonal line of the wire rod 27 is made run parallel or crossed at right angles in the axial direction of the winding core section 29. Accordingly, since there are the circular arc sections 28 at the corner sections of the wire rods 27, the rate of deformation is small, the formation of pinholes can be decreased, infulating property is ameliorated, the arranging property of the winding is improved and the space factor can be increased.
