樹脂４のヒンジ７にボルト８によって固定さねている。DETAILED DESCRIPTION OF THE INVENTION [Field of Commercial Use and Prior Art] The present invention relates to a resin mold type intensifier used in household washing machines and the like. Small electric motors used in washing machines, etc., generally have a stator attached to a frame with fixed bearings, but in order to simplify insulation and prevent fires, the stator is molded with resin. Relaxation frailty;
May be used. Figure 1 shows a conventional electric motor of this type, with 1 a stator core, 2 a coil, and 6 one bearing.
The dough 4 is molded with resin 4 to form the stator side. 5 is a bracket that supports the other bearing 6, and is fixed to the hinge 7 of the molded resin 4 with bolts 8.

Furthermore, if the hinge 7 of the molded resin is damaged due to poor molding or carelessness in handling, there is a drawback that assembly becomes impossible. The object of the present invention is to provide a resin molded electric motor free from such drawbacks.

施例を示している。[Structure of the Invention] The resin mold mold 111 of the present invention has the following features:
In a structure in which a stator side including a stator core and a coil is molded with TM resin and supported by a bracket, a part of the stator core is exposed outside the mold resin, and a through hole is provided in the exposed part. An embodiment of the present invention, which is characterized by the following, will be described with reference to FIGS. 2 to 4. In FIG. 2, numerals 2 to 10 indicate the same components as in FIG. 1, and the structure thereof is also the same. In the present invention, a portion of the stator core 1 is exposed outside the molded resin 4, and the exposed portion 11 is provided with a through hole 12. In Figure 2, since the hinge 7 is missing, the bracket 5 is attached to the auxiliary metal fitting 13.
FIG. 4 shows an example in which a deformable bracket 14 is used.

(1) Since a part of the stator core 1 is exposed outside the molded resin 4, cooling is performed effectively. The through holes 12 increase the heat dissipation area and improve the cooling effect. (2) If the hinge 7 is poorly formed or damaged, the conventional product shown in FIG. is possible.

Because it is possible to do this, there is less loss during punching and the material utilization rate is high. (4) In the conventional structure shown in Fig. 1, the stator core and the entire coil are molded, making it difficult to position them during molding, but in the present invention, a part of the stator core is exposed. This makes positioning easy and improves assembly productivity.
