摘要： A rotating machine having a stator core and being equipped with coolers for cooling a cooling medium which is circulated inside the machine by the rotation of a fan installed near a rotating axis of the rotating machine. The coolers are installed in a ventilation passage for the cooling medium and include a primary cooler installed in a primary ventilation passage extending from an exhaust side of the fan to a suction side of the fan via the stator core, and a secondary cooler installed in a secondary ventilation passage extending from the exhaust side of the fan in the primary ventilation passage to an inside of an inner surface of the stator core via the stator core.

摘要： There is provided an electric rotary machine having, in particular, a large capacity, in which a volume of cooling air is ensured for the axially center part thereof so as to make the temperature distribution uniform in the axial direction of the rotor and the stator. Each of gas coolers in the electric rotary machine is divided into not less than two of passage parts in which streams run in two directions in opposite to each other are created, and a stator-cooling connection passage is formed so as to connect not less than two passage parts located in the radially outward part of the stator 2 and axially defined by partition walls with the passage parts in the gas coolers in the electric rotary machine. With this arrangement, cold gas can be led into the axially center part of the stator without increasing the total ventilation resistance, and accordingly, it is possible to prevent occurrence of temperature rise in the axially center parts of the stator and the rotor, which would be caused in the electric rotary machine having, in particular, a large capacity.
