ける等の課題を有していた。Problems to be Solved by the Invention However, in such a structure, when the resin molding material 3 is removed, the stator coil 2 is pushed up to the press-fitted part of the bearing nozzle 4 due to the flow of unassimilated resin. If the stator coil L'2 is pushed out, the dielectric strength and lightning surge voltage between the live part and the bearing housing 4 do not meet the standards, or the stator coil L'2 is pushed out to the bearing housing contact surface.
There were problems such as damaging the stator coil 2 when press-fitting the bearing housing.
本発明は上記課題に鑑み、樹脂製モールド材の流れによ

。Operation With the above configuration, when resin molding is performed, the coil is stopped at the bottom of the groove by the mold forming the groove, and is fixed to the bearing housing with an interval equal to the depth of the groove. Therefore, a design can be made that sufficiently satisfies dielectric strength and lightning surge.

いる。EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. In the figure, the stator is constructed by winding stake coils/I/9 around the stator core 8, which is the main part of the stator, and the entire stator is molded with a resin molding material 1o.
It is covered with The bearing 13 for holding the shaft 12 with the rotor 11 compressed is still attached to the bearing 14.
The resin mold material 10 is held at the central portion thereof and is compressed.

As shown in FIG. 2, when a stator coil ZV9 or the like is molded with a molding material 10 made of wood M''iI, the stator coil 9 is likely to be pushed out toward the inner circumference by the flow of the resin molding material 1o. By forming a plurality of convex portions around the part of the mold that contacts the bearing housing 14 during molding, the flow of the stator coil/L/9 is stopped at the convex portions.
It is not pushed out to the contact surface with the bearing nozzle 14.

Since the insulation distance of the stator coil can be ensured, a design that satisfies the dielectric strength and lightning surge resistance can be achieved.
