フアンカバー、１０は端子箱である。 A generally known stator for this type of rotating electric machine is shown in FIGS. 1 and 2. In the figure, 1 is a stator core, 2 is a rotor core, and 3 is a corrugated steel plate outer frame that is attached to the outer periphery of the stator core 1 and is formed by corrugating a thin steel plate to form axial fins 3a. 4 is a flange, 5 is a bracket, 6 is a rotating shaft, 7 is an internal fan, 8 is an external fan, 9 is an external fan cover, and 10 is a terminal box.

３ａの内部を内気の通風路、フイン３ａ間を外部
通風路としているものである。 As described above, the conventional rotating electrical machine has the corrugated steel plate outer frame 3 attached to the outer periphery of the stator core 1, and the inside of the fins 3a is used as an internal air ventilation path, and the space between the fins 3a is used as an external ventilation path.
従来は以上のように固定子鉄心１の外周に波形
鋼板外枠３を装着しただけであるため、軸方向、
あるいは周方向に対する剛性が悪く、回転電機全
体に対し変形が生ずる欠点があつた。 Conventionally, as described above, only the corrugated steel plate outer frame 3 was attached to the outer periphery of the stator core 1.
Another disadvantage is that the rigidity in the circumferential direction is poor, resulting in deformation of the entire rotating electric machine.
この考案は以上のような欠点を解消することを

部材を固着することによつて剛性をもたせるよう
に構成した固定子を提供するものである。 This idea was made with the aim of eliminating the above-mentioned drawbacks.The fins of the outer frame of the corrugated steel plate were skipped at required locations, and reinforcing members were fixed to these locations to provide rigidity. The present invention provides a stator constructed in the following manner.
以下この考案の一実施例を図に基づいて説明す

た部分に固着され軸方向に上記フイン１１ａと平
行して固着された平角状の補強材である。 An embodiment of this invention will be described below based on the drawings. In FIGS. 3 and 4, reference numeral 11 denotes a corrugated steel plate outer frame that is attached to the outer periphery of the stator core and is made by bending a thin steel plate in a wave shape to form a plurality of axial fins 11a. In this case, the fins 11a are skipped at required positions in the circumferential direction. Reference numeral 12 denotes a rectangular reinforcing member that is fixed to the portion of the corrugated steel plate outer frame 11 where the fin 11a is skipped, and is fixed in parallel with the fin 11a in the axial direction.
なおその他の構成は従来と同様であるから説明
を省略する。 Note that the other configurations are the same as those of the prior art, so explanations will be omitted.
この考案は以上のように、固定子鉄心１の外周

所要個所だけスキツプさせ、このスキツプさせた
部分に補強材を固着するように構成したもので、
これにより軸方向、周方向に対する剛性UPが期
待できる。 As described above, this invention is constructed so that the fins 11a of the corrugated steel plate outer frame 11 attached to the outer periphery of the stator core 1 are skipped at required locations, and reinforcing material is fixed to the skipped locations. ,
This can be expected to increase rigidity in the axial and circumferential directions.
なお、内部通風路がいくらか少なくなるが、こ
の分は固定子鉄心１から補強材１２への直接伝達
される熱の移動によつて冷却を行なうとになるの
で、十分カバーできる。 It should be noted that although the internal ventilation passages are somewhat reduced, this can be sufficiently compensated for by cooling by the transfer of heat directly transferred from the stator core 1 to the reinforcing material 12.
この実施例では補強材１２の平角状のものを使
用した例を示したが、この形状は適当に変更して
よいことはもちろんである。 Although this embodiment shows an example in which a rectangular reinforcing member 12 is used, it goes without saying that this shape may be changed as appropriate.
以上のようにこの考案によれば、回転電機の剛
性を増すことができ性能、品質の良好な回転電機
の固定子を得ることができる。 As described above, according to this invention, the rigidity of the rotating electrical machine can be increased and a stator for the rotating electrical machine with good performance and quality can be obtained.
