た。 In such a mounting structure, it is necessary to machine screw holes for bolt fastening in the stator frame 5 and the stator core holding cover 6, and the larger the machine, the more man-hours are required, which tends to increase the manufacturing cost. It was hot.
本考案は上述した欠点を除去するもので、加工
工数の少ない経済的な固定子コイル支持具の取付
構造を提供せんとするものである。以下本考案を
実施例図面に基づき詳細に説明する。 The present invention aims to eliminate the above-mentioned drawbacks and provide an economical stator coil support mounting structure that requires less processing steps. The present invention will be explained in detail below based on the drawings of the embodiments.

ることは言うまでもない。 In FIGS. 3 and 4, the coil support 4 is composed of a support rod 4a and a support base 4b as in the conventional case, but as shown in the figure, the support rod 4a is composed of a support base 4b.
In addition, instead of the plurality of holes for fastening bolts, holes are drilled at appropriate positions in the support base 4b through which the studs 8 for tightening the stator core are inserted. The length of the stud 8 for tightening the core is made slightly longer, and the coil support 4 is fastened to the stator core holding cover 6 using the nut 9 using the tip end thereof. In addition, the third
Although the illustrations in FIGS. 4 and 4 show the case where the stator coil support 4 is attached to the stator core holding cover 6, it goes without saying that it is similarly fastened when attached to the other stator frame 5. .

大きく、信頼性の高い固定子コイル支持具４の取
付構造になる。 In such a mounting structure, it is not necessary to machine screw holes in the fixed frame 5 and the stator core holding cover 6, and the manufacturing cost is reduced. Furthermore, the fastening strength is sufficiently large, resulting in a highly reliable mounting structure for the stator coil support 4.
以上説明したように本考案によれば、従来に比
べ経済的で、しかも締結強度も十分に大きく信頼
性の高い固定子コイル支持具の取付構造が得られ
る。 As explained above, according to the present invention, it is possible to obtain a mounting structure for a stator coil support that is more economical than the conventional one and has sufficiently large fastening strength and high reliability.
