とする外面通風形回転電機。 A ventilation cover with a U-shaped cross section is attached to the outer periphery of one end of the electric machine body, and an intake port is provided on the outer periphery of this ventilation cover, and the cooling air taken in from this intake port is uniformly guided in the axial direction toward the outer periphery of the main body. An air guide with a trapezoidal cross section is mounted on the inner surface of the ventilation cover with its small diameter section facing the main body and eccentrically formed so that the ventilation resistance between the air guide and the ventilation cover increases as the distance from the intake port in the circumferential direction increases. An externally ventilated rotating electric machine characterized by:
