る。In the AC generator in which the fans 20 and 22 are attached to the rotor 4, when the rotation speed of the rotor 4 is low, the elastic blades 21 have a discharge angle θ as shown by the solid line in FIG. There is. When the rotation speed becomes high, each elastic blade 21 is elastically curved in the anti-rotational direction by the wind pressure, as shown by the chain line in FIG. 2 (the chain line shows only two) in the upper side. As a result, the ejection angle θ becomes smaller. Similarly, in the fan 22, the upper side of each elastic blade 23 is elastically curved in the anti-rotation direction due to the wind pressure, and the discharge angle θ is reduced. The elastic blades 21 and 23 of the fans 20 and 22 are arranged such that the centrifugal force acts on the upper side in the radial direction due to the rotation, but the force in the counter-rotation direction due to the wind pressure exerts a greater force.

When the rotation speed N becomes high, the cooling air flow rate Q becomes smaller than the conventional Q 1 . Therefore, the wind sound level P is also lower than the conventional P 1 , and the noise is reduced. It should be noted that although the temperature rise T of each component is higher than the conventional temperature T 1 due to the decrease of the air volume Q, it is lower than the temperature rise at the intermediate portion of the rotation speed N, and there is no problem.
