たことを特徴とする回転電機。 An air cooler that is attached to the upper part of the stator frame and through which cooling water can pass; a water leakage detection device that detects water leakage from the air cooler; and a tightening member for attaching the bearing device to the stator frame. In a rotating electric machine equipped with a rotary electric machine, a through hole is provided in the longitudinal center of the tightening bolt near the entrance through which the cooling air cooled by the air cooler is introduced into the inside of the rotary electric machine, and a through hole is provided in the longitudinal center of the tightening bolt. A rotating electric machine characterized in that the water leakage detection device is inserted to catch water droplets that leak from the air cooler and are blown away along with the flow of cooling air.
