Being with lattice coil 400 differences in lattice coil 500, is that totally 4 on 2 groups of 2 lines (4A, 4B, 4a and 4b) are arranged around the radical of rolling up the wire rod on the core 2.The wire rod running face is relative positive 2a and these two faces of back side 2c, and the amount of feeding of wire rod is the amount of 2 wire rods on face separately.The plane 2b of other two faces and bottom surface not feeding of the 2d amount of feeding.Thus, the wire rod multilayer around the volume core 2 on the time, at positive 2a and back side 2c, the winding direction of the wire rod on lower floor and upper strata is opposite.Like this, lattice coil 500, the cross part 5 that on positive 2a and back side 2c, has the wire rod intersection on lower floor and upper strata.In addition, lattice coil 500 in the end of positive 2a and back side 2c, has the torsional part 6 that 2 wire rods that rise to the upper strata from lower floor reverse and the arrangement of wire rod is replaced.
Followingly describe with regard to the method for winding of lattice coil 500 with reference to Fig. 8.
(1) be that the same one side of the volume core 2 of square shape begins to twine 2 groups of 2 wire rod 4A, 4B, 4a and 4b side by side from section.
(2) as shown in Figure 8, at the amount of feeding of the amount of positive 2a and 2 wire rods of back side 2c feeding, at the plane 2b and bottom surface not feeding of the 2d amount of feeding.In addition, in volume core 2 ends, the gap of the amount of 0.5 wire rod of residue and being wound the line.
(3) at positive 2a end face as the wire rod running face, shown in Fig. 8 (a), the amount of feeding of the wire rod 4A of volume in-core side and the amount of 2 wire rods of 4B feeding and being wound the line.In addition, 2 wire rod 4a in the volume core outside and 4b when rising to the wire rod 4A of lower floor and 4B and going up, are reversed and the arrangement of wire rod is replaced.In addition, the concrete method for winding of wire rod 4a and 4b is identical with the method for winding of the torsional part 6 of lattice coil 400.
(4) plane 2b below, shown in Fig. 8 (b), 4A, 4B, 4a and 4b under the situation of the not feeding amount of feeding by on volume core 2 ends.
(5) at the back side 2c as the wire rod running face that follows, shown in Fig. 8 (c), 2 wire rod 4A of lower floor and 4B are reversed and the arrangement of wire rod is replaced when lower floor rises to the upper strata.In addition, 2 wire rod 4a on upper strata and 4b are with the amount of feeding of the amount of 2 wire rods of lower floor's winding direction feeding on the contrary and wound the line.In addition, the concrete method for winding of wire rod 4A and 4B is identical with the method for winding of the torsional part 6 of lattice coil 400.
