に設けられた外扇と、この外扇によつて発生した
冷却風を導入して、上記ブラケツト内の内気を冷
却するエアクーラとを備えた回転電機において、
上記外扇によつて発生した冷却風の一部を、上記
内気の熱の影響を受けないように導入する冷却風
路と、この冷却風路に導入した上記冷却風を、上
記回転子軸の他端を支持する反外扇側軸受部近傍
に導出する導風箱とを備えた回転電機。 A rotor equipped with an external fan provided at one end of the rotor shaft whose end protrudes outside the bracket, and an air cooler that cools the inside air in the bracket by introducing cooling air generated by the external fan. In electrical equipment,
A cooling air path introduces a part of the cooling air generated by the outside fan so as not to be affected by the heat of the inside air, and the cooling air introduced into this cooling air path is connected to the rotor shaft. A rotating electric machine including a wind guide box led out near a bearing portion on the side opposite to the fan side that supports the other end.
