Abstract
In a method for correcting a coil wound in two layers, the coil is corrected as follows: a conductor is wound from an outside layer toward an inside layer to form a first row; the conductor is wound from the inside layer toward the outside layer to form a second row; the conductor is wound from the outside layer toward the inside layer to form a third row; a crossover portion is formed by connecting adjacent rows of the conductor; and a load is applied to the crossover portion from a coil correcting die through a crossover-portion correcting die so as to push first and second ends of the crossover portion along adjacent rows and move an intermediate portion of the crossover portion to an adjacent row.
Claims19
A method for correcting a coil made of a conductor wound in two layers that are an inside layer and an outside layer, comprising the steps of:
- providing a coil that includes a first row formed of the conductor wound from the outside layer toward the inside layer, a second row formed of the conductor wound from the inside layer toward the outside layer, a third row of the conductor wound from the outside layer toward the inside layer, and crossover portions of the conductor connecting the adjacent rows;
- providing a coil correcting die configured to apply a load to the coil in an arrangement direction of the first row, the second row, and the third row, to correct the coil;
- clamping the crossover portions by crossover-portion correcting dies placed on both sides of each crossover portion in the arrangement direction;
- and
- applying the load to the crossover portions by the coil correcting die through the crossover-portion correcting dies to make a first end portion and a second end portion of each crossover portion extend along the adjacent rows, and make an intermediate portion between the first end portion and the second end portion extend to shift to the adjacent rows.
