この発明は回転電機の固定子製造方法に関するものてあ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a stator for a rotating electric machine.
従来、一般に知られている銅板外枠回転電機として第１
図および第２図に示すものがあつた。Conventionally, it was the first known copper plate outer frame rotating electric machine.
The items shown in Figures and Figure 2 were found.
図において、１は固定子鉄心、２はこれと所定間隙を介

、８は回転子２と一体に回転する回転軸である。In the figure, 1 is a stator core, 2 is a rotor that faces the stator core through a predetermined gap, and 3 is an outer frame that is provided around the stator core 1 by bending a thin steel plate into a corrugated shape. It is composed of a cooling fin 31 formed of a corrugated peak portion and a contact surface portion 32 formed of a corrugated trough portion and in contact with the outer periphery of the stator core and a flange to be described later. 4 is steel plate outer frame 3
5 is a bracket attached to the flange 4, 6 is an internal fan, 7 is an external fan, and 8 is a rotating shaft that rotates together with the rotor 2.
なお、９は内部ファン６によつて通気される内気通路、
１０は外部ファン７によつて通気される外気通路である
。Note that 9 is an internal air passage ventilated by the internal fan 6;
10 is an outside air passage ventilated by an external fan 7.
次にこれらの構成について説明する。Next, these configurations will be explained.

による外気通路１０が形成されている。An outer frame 3 made of a thin steel plate formed into a corrugated shape is attached to the outer periphery of the stator core 1 so as to seal the inside air, and an inside air passage 9 for an internal fan 6 is provided inside the outer frame 3, and an external fan 7 is provided for the outside.
An outside air passage 10 is formed.

において、外枠と固定子鉄心の溶着の際、固定子鉄心表
面に被覆された絶縁剤が溶融し、溶接部にブローホール
として介在し、溶接部の強度低下および熱伝導の減少に
よる冷却効果の悪化などの欠点があつた。Therefore, when the rotor 2 rotates, the cooling air is directed by the internal fan 6 and external fan 7, which are respectively attached to the rotating shaft 8, in the directions indicated by the dotted line arrow (inside air path) and the solid line arrow (outside air path) in FIG. It circulates and passes through the air to cool the rotating electrical machine. The outer frame 3 is fixed to the outer periphery of the stator core 1 at a contact surface 32 by welding or the like. In conventional configurations like this, when the outer frame and stator core are welded, the insulating material coated on the surface of the stator core melts and forms blowholes in the weld, reducing the strength of the weld and causing heat conduction. There were drawbacks such as deterioration of the cooling effect due to a decrease in the amount of water.
この発明は上記のような欠点を除去するためになされた
もので、外枠と固定子鉄心の溶着部にブローホールが発
生しない回転電機の固定子製造方法を提供することを目
的としている。The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a method for manufacturing a stator for a rotating electric machine in which blowholes do not occur at the welded portion of the outer frame and the stator core.
以下この発明の一実施例を第３図および第４図について
説明する。An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.
図において、１１は積層された固定子鉄心１の外周を溶
融して固着された溶着部である。なお、その他の構成は
従来と同様なので説明を省略する。In the figure, reference numeral 11 denotes a welded portion that is fixed by melting the outer periphery of the stacked stator cores 1. Note that the other configurations are the same as the conventional one, so explanations will be omitted.
上記のように積層固定子鉄心１の外周をバーナ等で溶融
し、固定子鉄心１の表面に被覆された絶縁剤を完全に燃
焼させ溶着部１１を形成する。As described above, the outer periphery of the laminated stator core 1 is melted using a burner or the like, and the insulating agent coated on the surface of the stator core 1 is completely burned to form the welded portion 11.
この溶着部１１に外枠３の接面部３２を溶接等で固着す

外周を予め溶融して溶着部を形成し、この溶着部と外枠
とを溶接等で固着するように構成したので、絶縁剤の燃
焼によるブローホールの発生がなく、強固で熱伝導性の
よい固着部が得られる効果がある。The contact surface portion 32 of the outer frame 3 is fixed to this welded portion 11 by welding or the like. As described above, according to the present invention, the outer periphery of the laminated stator core is melted in advance to form a welded part, and the welded part and the outer frame are fixed by welding or the like, so that the insulating material burns out. This has the effect of providing a strong bonded part with good thermal conductivity without the occurrence of blowholes.
