A ventilation system for an electric rotating device is provided to make the excellent temperature uniformity by dividing the air circulating to the radial direction between steel and sheet bunches. A ventilation system for an electric rotating device(5) comprises a casing(2) and a stator(6). A stator is mounted on the casing. The electric rotating device comprises an air feed parts(27,31), a second air circulating part(21) and air collection parts(28,32). The air feed part throws the ventilation air into the axial direction to the electric rotating device from the first air circulating part. The first air circulating part circulates the ventilation air to the axial direction within a rotor area. The second air circulating part circulates ventilation air to the axial direction within a stator area. The air collecting part collects the ventilation air coming from the second air circulating part. The ventilation air consecutively circulates within the electric rotating device. |
