Abstract:
1. 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.
