However, welding causes thermal deformation and the welding operation itself is not easy.
そこで最近は通しボル ト による締結方法を採用する場合が 多く なつてきた。 その場合ステータコアと前後のハウジング との締結組立工程においては、 ステ一タコアの孔であって、 上記通しボル ト挿入用の孔には通しピンを挿入し、 この通し ピンをステータコァの両端において治具に仮保持させること によって該ステ一タコアを仮固定し、 この状態で巻線を施す 作業を行う。 巻線を施す作業の終了後、 上記通しピンを引き 抜き、 代わりに通しボルトを挿入して前後のハゥジングとス テータコァとを締結している。 Therefore, recently, the bolt-type fastening method has often been adopted. In this case, in the fastening assembly process between the stator core and the front and rear housings, a through pin is inserted into the hole of the stator core, which is a hole for inserting the through bolt, and the through pins are jigs at both ends of the stator core. The stator core is temporarily fixed by temporarily holding it, and winding work is performed in this state. After the work of applying the winding is completed, the through pin is pulled out and a through bolt is inserted instead, and the front and rear housings and the stator core are fastened.
然しながら上述の通しボル ト による締結方法は、 小型 （又 は中型） のモータにおいては通しピンの長さは比較的短く、

In addition, since it is light in weight, it is easy to pull out after inserting and winding.However, in the case of a large motor, for example, a motor whose weight exceeds 400 kg, the length of the through pin is long and the weight It was not easy to handle because of the large size, and the fastening method using through bolts was not adopted.

The stator core 10 of the motor is formed by laminating a plurality of (many) annular element plates 40. Each of these Holes are provided near the outer periphery of the annular element plates 40 at the same positions so as to form through holes 42 when the respective annular element plates 40 are stacked to form the stator core 10. . Each of the annular element plates 40 is provided with a plurality of (for example, four) holes at equal angular positions in the circumferential direction. Therefore, the stator core 10 has a plurality of through-holes 42 parallel to the rotation center axis 44 of the motor. It is necessary to apply a winding to this slot hole, and the stator core 10 must be temporarily fixed during this winding work. Therefore, in the present embodiment, a through pin longer than the length of the stator core 10 is provided in the through hole 42 of the stator core 10.
