There were other methods. In addition, in FIG. 6, 14 is a stator coil.

テータコア１２の軸心とが一致し難いという欠点があっ
た。However, in the conventional fixing method described above, the frame 11 is fixed one by one by driving the bottle 13, inserting a screw, or by spot welding. There was a drawback that it was difficult for the axis of the stator core 12 to coincide with the axis of the stator core 12.
また、ステータコア１２の一部がフレーム１１に固定さ
れているため一部に大きな応力がかかり、薄い珪素鋼板
の積層体で構成されるステータコア１２に歪みを与え、
振動、磁気音及び固定力が弱い等の欠点があった。In addition, since a part of the stator core 12 is fixed to the frame 11, a large stress is applied to the part, which causes distortion in the stator core 12, which is made of a laminated body of thin silicon steel plates.
It had drawbacks such as vibration, magnetic noise, and weak fixing force.
また、フレーム１１とステータコア１２の間にギャップ
があるたのステータコア１２等からの熱の放散が悪いと
いう欠点もあった。Furthermore, since there is a gap between the frame 11 and the stator core 12, there is also a drawback that heat dissipation from the stator core 12 and the like is poor.
本発明は上述の点に鑑みてなされたもので、上記問題点

により、前記ステータコアをフレーム内に固定した。In order to solve the above-mentioned problems, the present invention makes the inner diameter of the frame slightly larger to the extent that the stator core can be easily inserted, the stator core is inserted into the frame, and a plurality of belt-shaped molten beads are formed in the longitudinal direction of the outer peripheral surface of the frame. The stator core was fixed within the frame by shrinking the inner diameter of the frame as the belt-shaped molten bead cooled.

のフレームとステータコアの固定に好適である。By fixing the electromechanical frame and the stator core in the above method, the stator core comes into contact with the inner circumferential surface of the frame over most of its outer circumferential surface, so that the axis of the frame and the axis of the stator core can easily be aligned. Stable rotation characteristics can be obtained. It is particularly suitable for fixing the frame and stator core of a submersible motor for deep wells with a narrow diameter and a long length.

とになるから、磁気的不平衡がなくなり、始動が滑らか
となり、磁気音及び振動等も発生しない。Furthermore, since the axis of the frame and the stator core are aligned, the mechanical center and the magnetic center are aligned, which eliminates magnetic imbalance, smooths startup, and eliminates magnetic noise. No vibrations occur.

ームとステータコアとの固定力が極めて強固になる。In addition, the frame tightens and fixes the stator core with force due to the contraction of the multiple belt-shaped molten beats formed in the longitudinal direction of the outer peripheral surface of the frame during cooling, so the fixing force between the frame and stator core is extremely high. Become strong.
また、ステータコアがその外周面の大半部分でフレーム

That is, a collet 18-2 is arranged around the outer periphery of the tungsten electrode 18-3, and a gas nozzle 18-1 is arranged around the outer periphery of the cholera 1B-2. When a predetermined voltage is applied to the tungsten electrode 18-3, an arc 20 is generated in the gap between the tip of the tungsten electrode 18-3 and the frame 11. Further, argon gas 19 is injected from the gas nozzle 18 - 1 around the eroding arc 20 .

。After forming the band-shaped molten bead 11a, the frame 11
is rotated by a predetermined angle (60° in FIG. 4(a)) to form the same belt-shaped molten bead 11a, and a plurality of belt-shaped molten beets 11a are formed on the outer peripheral surface of the frame 11 at predetermined intervals.

１２の軸心とはずれることはない。As mentioned above, the outer surface of the frame 11 is covered with a belt-shaped molten beet.
a, the inner diameter of the frame 11 contracts due to cooling of the band-shaped molten bead 11a, and the stator core 1
2 is firmly fixed within the frame 11. Moreover, since the band-shaped molten bead 11a is formed symmetrically on both sides of the frame 1'1, the axial center of the frame 11 and the axial center of the stator core 12 do not deviate from each other.

この部分の軸心もずれることなくステータコア１２の軸
心とフレーム１１の軸心は一致する。In addition, since the range in which the band-shaped molten bead 11a is formed is formed a predetermined distance inward from both ends of the stator core 12, the inner diameter of the frame 11 in this area contracts until it comes into close contact with the outer peripheral surface of the stator core 12, but exceeds both ends of the stator core 12. Since there is no change in the inner diameter dimension of the frame 11 at this portion, the axis of the stator core 12 and the axis of the frame 11 coincide with each other without shifting the axis of this portion.

安全な固定力であることが確認できた。Furthermore, as described above, the stator core 12 is provided within the frame 11.
When the stator core 12 is fixed, most of the outer surface of the stator core 12 is in close contact with the inner surface of the frame 11, so there is no gap between the inner surface of the frame 11 and the outer surface of the stator core 12, and the heat generated inside the stator core 12 is efficiently transferred to the frame 11. In the frame 11 and stator core 12 having the above-mentioned shapes, for example, the stator core 12 has an outer diameter of 170 ml+, a wall thickness of 0.6111 m, and an inner diameter of 170 m. Using the frame 11 of .3■, apply a current of 15 OA to the tungsten electrode 18-3 of the TIG welding torch 18, and
When the G welding torch 18 is allowed to move at 1°0 II in/min and the stator core 12 is fixed within the frame 11 by forming six belt-shaped molten beets lla on the outer periphery of the frame 11, the fixing force of the stator core 12 is approximately 1000 kg- m
becomes. Normally, the torque applied between the frame 11 and the stator core 12 due to the starting torque of a submersible electric motor configured with the frame 11 and stator core 12 having the above dimensions is 25
kg-m, it was confirmed that the fixing force of 1000 kg-m is a sufficiently safe fixing force.

When the belt-shaped molten bead 11a is formed in the same way as above at the position of the outer surface corresponding to the squared surface 12d, the frame 11
It deforms and contracts as shown by the dashed line and bites into the inner circumferential surface of the frame 11, further improving the fixing effect.
