    • Drip-proof type electrical rotating machine having inlets and outlets for air flow formed below a rotating shaft supported by a frame. The inlets are formed on end brackets located at both sides of a stator core, and cooling fans rotating together with the rotating shaft are provided on a rotor in opposite to both of the end brackets. Air guides are provided between the inlet and the cooling fans, each air guide being provided with an air passing hole. When the air guide is assembled into the frame, the distance from the axis of the rotating shaft to an above edge of the air passing hole is shorter than the distance from the shaft axis to an lower edge of the air passing hole. With such a construction, the upper edge portion of each air passing hole above the rotating shaft substantially prevents air taken-in from backwardly flowing out therethrough, and the lower edge portion under the shaft permits an effective air suction therethrough from the inlet, thus resulting in improvement of cooling effect of the rotating machine.
    • 防滴型旋转电机具有形成在由框架支撑的旋转轴下方的用于气流的入口和出口。 入口形成在位于定子芯的两侧的端托架上,并且与转轴一起旋转的冷却风扇设置在与两个端托架相对的转子上。 在入口和冷却风扇之间设置有空气引导件,每个空气引导件都设有通气孔。 当空气引导件组装到框架中时,从旋转轴的轴线到通气孔的上边缘的距离比从空气通过孔的轴线到下边缘的距离短。 通过这样的结构,旋转轴上方的每个空气通过孔的上边缘部分基本上防止从其中向外流出的空气,并且轴下方的下边缘部分允许有效的空气从入口吸入,从而导致 在改善旋转机器的冷却效果。
