    • A rotating electrical machine includes: a rotor comprising a rotor core and a field winding wound round the rotor core; and a stator comprising a stator core and a stator winding wound round the stator core. The stator is arranged in opposition to the rotor with a predetermined spacing therebetween. the stator core is formed by punching a split piece, which comprises teeth for insertion of the stator winding thereinto and a core back on an outer periphery thereof, from a magnetic steel sheet, and laminating a plurality of those circular configurations in an axial direction, in which a plurality of the split pieces are arranged in a circle in a circumferential direction. The stator core has magnetic steel sheets, which are different in magnetic permeability in a diametrical direction, laminated at an axial end region of and in an axial central region of the stator core.

    • 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.
    • 提供了一种特别是大容量的电动旋转机械,其中确保了其轴向中心部分的体积的冷却空气,以使得转子和定子的轴向上的温度分布一致。 电动旋转机械中的每个气体冷却器被分成不少于两个通道部分,其中流动沿彼此相反的两个方向流动,并且形成定子冷却连接通道,以便连接不小于 两个通道部分位于定子2的径向向外的部分中,并且由电动旋转机械中的气体冷却器中的通道部分间隔开。 通过这种布置,可以将冷气导入定子的轴向中心部分,而不增加总的通风阻力,因此,可以防止定子和转子的轴向中心部分的温度升高的发生, 在具有特别大容量的电动旋转机械中引起。
