転電機。 A large number of axial heat dissipation fins are provided radially on the outer periphery of both ends of a cylindrical frame except for the center part, and a ventilation cover is attached to the outer periphery of the frame to surround it and has a cooling air inlet in the center part. In an external ventilation rotating electric machine, an axial partition plate is provided on the inner surface of the inlet of the cover to uniformly divide the cooling air in the circumferential direction, and a circle is formed on the outer periphery of the frame at the same axial position as the inlet. An external ventilation rotating electric machine characterized in that the circumferential ventilation passage is narrowed by increasing the length of the heat dissipation fins as the distance from the suction port increases.
