    摘要： Efficient ventilation and cooling for a rotor is realized at a low cost by reducing the pressure loss at inlet flow passages, which lead to axial flow passages through which cooling gas flows to the rotor. Inlet flow passages leading to axial flow passages for cooling an interior of the rotor are composed of convex portions, which are formed axially on surfaces of a rotor spindle between and below coil ends of the rotor, and concave grooves formed between the convex portions. Also, the convex portions are designed to have a height increasing toward a downstream side, and assuming that L designates an length of the convex portions, L is greater than a radial difference between the positions of a maximum radius and a minimum radius of the convex portions.

    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.

    摘要： A rotating electric machine exhibits a substantially level axial temperature rise distribution by supplying a coolant which is sufficiently cooled to a central portion of an iron core which is most distant from each of the axial ends of the iron core. A plurality of ventilating passages, which continuously extend in the peripheral direction, are provided in the axial direction between a stator frame and a stator iron core, and coolers are provided in the ventilating passages. A coolant boosted by a booster is cooled by the coolers and is allowed to flow to a central portion of the stator iron core in the direction from the outer peripheral side to the inner peripheral side of the stator iron core via ventilating passages which communicate with the central portion of the stator iron core.
