鉄心に係り、特に、回転電機鉄心の半径方向に通風ダク
トもつ回転電機鉄心に関する。Description: TECHNICAL FIELD The present invention relates to a rotary electric machine core such as an AC generator or an induction motor, and more particularly to a rotary electric machine core having a ventilation duct in a radial direction of the rotary electric machine core.

ウエルド３で溶着する。The rotating electric machine stator core has a structure as shown in FIG. The core blocks 1A1 to 4 in which a plurality of thin iron plates are laminated are provided between each other and to the core end ventilation ducts 2A1 to 5 for cooling the core. This ventilation duct is the fourth
As shown in the figure, the duct piece 2B1 is welded to the contact plate 2C1 by the spot weld 3.

鉄心スロツト４内に及ぶのを防止するためである。At this time, the abutting plate 2C1 is a single piece, and is processed by a punching die having a width G4 and a depth G5 larger than the dimensions of the iron core slot 4. G4 and G5 are usually 0.5 to 1.0 mm. This is because the heat generated when the duct piece 2B1 is welded to the contact plate 2C1 by the spot weld 3 prevents the deformation of the tooth 6 portion of the contact plate 2C1 from reaching the core slot 4.

G3 has a size of 1-2 mm.

ドで溶着する時に発生する熱でまくれが生じやすい。(Japanese Utility Model Laid-Open No. 59-164461, Fig. 2) [Problems to be solved by the invention] In such a stator core ventilation duct contact plate structure, the duct piece is applied to the contact plate at the tip of the contact plate teeth. The heat generated when welding with spot welds tends to cause blistering.

うにまくれｔが楔溝部よりギヤツプ側に発生する。As shown in Fig. 5, it is the tooth width W of the wedge groove of the plate.
Becomes very narrow, the composition of the tip end of the contact plate weakens, and due to the heat generated by the spot weld, a blistering t occurs on the gear gap side from the wedge groove as shown in FIG.

部分にワニスがたまる。For this reason, when the coil is inserted into the stator core slot and the core and the coil are integrated with an epoxy varnish or the like, there is a gap between the toothed plate brace portion and the core, and the varnish accumulates in this portion.
従つて、運転時に電磁振動等により、ワニスが落下し事
故に致ることがある。Therefore, the varnish may fall due to electromagnetic vibrations during operation, resulting in an accident.

明は達成される。In order to achieve the above object, it is necessary to have a structure in which the deformation (burl) of the tooth portion of the plate is minimized. Therefore, as a result of various studies, the present invention can be achieved by removing the portion on the gear side including the wedge groove portion where the spot weld of the contact plate portion is apt to be deformed (blown) due to heat.

る。When welding the duct piece to the plate with spot weld,
The object is achieved by removing the teeth of the wedge groove portion of the plate, which is most affected by the deformation (blurring) that occurs. At this time, the range in which the teeth of the contact plate are removed is best located at a position 1 to 2 mm away from the iron core wedge groove portion on the side opposite to the gear tap. The reason is that it is necessary to consider the deformation of the touch plate teeth portion and to change the length of the duct piece to be attached by deleting the touch plate teeth portion. Since the duct piece secures a space for passing air, the result of testing how much the duct piece opens in the axial direction of the iron core depending on the length of the duct piece was as shown in FIG. As a result, the hypotenuse is
There is no problem with opening the iron core even if the duct plate is removed and the duct piece is attached as described above. By carrying out at a distance of 1 to 2 mm to the gear side, the influence of the contact plate teeth inside the iron core wedge groove is eliminated.
以下、本発明の一実施例を第１図、第２図により説明す

ダクトピース長さでスポツトウエルドで取付ける。The slot 4 of the ventilation duct contact plate 2C1 is punched with a punching die having a large width G4 and depth G5 depending on the dimensions of the iron core slot 4 as in the conventional case. Next, remove the tooth part of the contact plate at a position G1 (1 to 2 mm) away from the iron core wedge groove on the side opposite to the gear and remove it to the inner and outer diameters as usual, and use spot welds with duct piece lengths that open G2 and G3 respectively. Install with.

より、当板テイースのまくれが発生せず、ワニスだまり
も起きない構造が得られる。By removing the toothed plate teeth on the gear tap side including the wedge groove portion, a structure can be obtained in which the toothed plate teeth do not curl up and varnish does not accumulate.
