When the rotating electric machine 1 rotates, cooling air is sucked in from the intake port 12 by the cooling fan inside the rotating electric machine 1, and the air passage 51 → the intake window 41 of the rotating electric machine 1 → the inside of the rotating electric machine 1 → the upper exhaust window 42 → ventilation. Path 36 → Central ventilation path 52 → Exhaust path 5
3 and is discharged from the exhaust port 13 to cool the rotating electric machine 1. The control device 5 is indirectly cooled by the wall 35 facing the intake channel 51 .

従来の回転電機収納室は以上のように、回転電
機から排出される風が通る排気窓が1個所しかな
いため、回転電機の発生熱量に見合うだけの冷却
風量を流すことが困難で、回転電機の出力が低く
抑えられているという欠点があつた。 As mentioned above, conventional rotating electrical machine storage rooms have only one exhaust window through which the air discharged from the rotating electrical machines passes, making it difficult to flow enough cooling air to match the amount of heat generated by the rotating electrical machines. The drawback was that the output was kept low.
この考案は上記のような従来の欠点を除去する
ためになされたもので、共通ベツド内に排気の通
風路を形成することにより、回転電機の排気窓が
2個所となり、冷却風量を増加することができる
回転電機装置を提供することを目的としている。 This idea was made to eliminate the above-mentioned drawbacks of the conventional system. By forming an exhaust ventilation path in the common bed, there are two exhaust windows for the rotating electric machine, increasing the amount of cooling air. The purpose of this invention is to provide a rotating electric machine that can perform the following functions.

めのスポンジ状ゴムからなるパツキンである。 An embodiment of this invention will be described below with reference to the drawings. 4 to 6, 15 is a lower exhaust window provided at the lower center of the frame 40 of the rotating electrical machine 1, 18 is an opening formed in the center of the top plate of the common bed 3, and 20 is an exhaust path. 53, an opening formed at the end of the top plate of the common bed 3, and 19 communicates between each opening 18 and 20 to utilize the space between the top plate and the bottom plate of the common bed 3. 37 is a ventilation passage that communicates between the lower exhaust window 15 of the rotating electrical machine 1 and the opening 18 of the common bed 3; 16 is a ventilation guide that surrounds this ventilation passage 37; It is composed of an L-shaped member provided between two mounting legs. Reference numeral 17 denotes a gasket made of sponge-like rubber for preventing leakage of exhaust gas between the ventilation guide 16 and the common bed 3.
なお、その他の構成は従来のものと同様である
から説明を省略する。 Note that the other configurations are the same as those of the conventional one, so explanations will be omitted.

に流れる。排気路53内に上及び下から入つて合
流した風は排気口13から排出される。 Next, the ventilation operation in this rotating electric machine device will be explained. The wind sucked in from the intake port 12 is introduced into the rotating electrical machine 1 through the intake window 41 of the rotating electrical machine 1 via the intake path 51. A portion of the wind that cools the rotating electric machine 1 flows from the upper exhaust window 42 to the exhaust passage 53 through the central ventilation passage 52 as in the conventional case. In addition, the remaining part of the air flows from the lower exhaust window 15 of the rotating electric machine 1 to the ventilation path 3.
7→ventilation path 19 of common bed 3→exhaust path 53 in this order. The wind that enters the exhaust passage 53 from above and below and merges is discharged from the exhaust port 13.

34に取付けてもよい。 Note that the sound reduction effect can be improved by pasting a sound absorbing material (not shown) around the ventilation passage 19 in the common bed 3. Further, the control device 5 may be attached to the floor 34 of the control device storage chamber 33.

回転電機の出力を大きくすることができるという
効果がある。 As described above, according to this invention, the top plate of the common bed is provided with openings that communicate with the lower exhaust window of the rotating electrical machine and the exhaust path of the cabinet, so that the exhaust air that cools the rotating electrical machine is routed to the common bed. Since the air is discharged through the ventilation path formed between the top plate and the bottom plate, the area of the exhaust window of the rotating electric machine can be approximately doubled compared to conventional ones.
Therefore, the amount of cooling air passing through the rotating electric machine increases, and if the size of the cabinet is the same as the conventional one,
This has the effect of increasing the output of the rotating electric machine.
