同様の課題がある。By the way, in the above-mentioned conventional winding method for the integral type iron core, the winding guide 21 is attached to the coil end portion, and the molded grooved insulator 22 is attached to align the winding. In the case of direct winding, there is a problem that the molded grooved insulator 22 cannot be removed, the surface area of the coil end portion decreases, and the cooling performance of the winding deteriorates. As a result, the current density of the rotor winding must be reduced, leading to an increase in the size of the salient pole rotor. In addition, because it is necessary to make a molded grooved insulator each time,
It was linked to higher costs. The same problem as described above is also encountered in a method in which a split type molded insulator 23 used in a small-sized salient pole rotor is fitted into a salient pole portion and is directly wound in alignment.
