供することにある。[Detailed description of the invention] This invention relates to the positioning of a bracket and a field core in a small electric motor, and its purpose is to
The object of the present invention is to provide a small-sized electric motor that can be easily assembled and requires significantly less bracket material by fitting the bracket and the field core.
従来、界磁コアの位置決め４は（図示せず）ブラケット
内に界磁コアを圧入することにより行われていた。Conventionally, positioning 4 of the field core has been performed by press-fitting the field core into a bracket (not shown).
しかしながら、このような方法ではブラケットの形状は
大きなものとなり余分な材料を必要とし、また、圧入作
業、位置決め作業が必要であり作業性の悪い欠点があっ
た。However, in this method, the shape of the bracket becomes large and extra material is required, and press-fitting and positioning work are required, resulting in poor workability.
本考案は以上の欠点に鑑み、これを改良するブラケット
を提供することにある。SUMMARY OF THE INVENTION In view of the above drawbacks, the present invention aims to provide a bracket that improves the above drawbacks.
以下、一実施例を示す図面に基き本考案を説明する。Hereinafter, the present invention will be explained based on the drawings showing one embodiment.
第１図において、１はブラケット、１ａは成形段部、１
ｂは打抜部を示す。In FIG. 1, 1 is a bracket, 1a is a molded step, 1
b indicates a punched portion.
第２図、第３図は上記各部分の断面図である。FIGS. 2 and 3 are cross-sectional views of each of the above parts.
第１図、第３図、第４図および第６図に示すように、ブ
ラケット１に界磁コア２が嵌合できるよう、第１図、第
２図および第５図に示すような成形段部１ａを残し、打
抜き部１ｂを設ける。As shown in FIGS. 1, 3, 4 and 6, in order to fit the field core 2 into the bracket 1, a molding step as shown in FIGS. A punched portion 1b is provided, leaving the portion 1a.
このようにしてきたブラケット１に、界磁コア２を打抜
き部１ｂにて嵌合し、成形段部１ａにて界磁コア２を受
けるようにして位置決めを行う。The field core 2 is fitted into the bracket 1 thus prepared at the punched portion 1b, and positioned so that the field core 2 is received at the molded stepped portion 1a.
上記のごとく嵌合、位置決めを行った後、第７図に示す

の種々の効果が得られるものである。As described above, in the small electric motor of the present invention, the field core can be easily positioned by providing a punched part and a molded part in the bracket, and the field core is press-fitted into the bracket and positioned as in the conventional case. Since there is no need for a detailed assembly process, it is possible to reduce the number of man-hours and the amount of bracket material used.Also, because an extremely simple structure with good workability is obtained, it is possible to significantly reduce the occurrence of defects. It is effective.
