Reference numeral 0b denotes an air passage that penetrates through the rotor winding 30 in the axial direction, and is arranged along the winding direction in two rows in the radial direction of the rotor winding 30. Then, similarly to the salient pole type rotor in the first embodiment, during the rotation operation of the salient pole type rotor, the cooling air flows directly into the ventilation hole 30a from the rotating shaft 13 side of the rotor winding 30. The cooling air flows into the ventilation hole 30b through the ventilation path 23.

a, 30b are arranged in two rows,
The cooling effect can be enhanced by increasing the contact area between the cooling wind flowing through the a and 30b and the rotor winding 30, and the rotor winding 30 can be uniformly cooled in the radial direction. In the second embodiment, the ventilation holes 30
a, 30b are arranged in two rows.
When the number of rows of the ventilation holes 30a and 30b is increased, the contact area between the cooling air and the rotor winding 30 is increased, and the cooling effect is further improved. However, if the number of rows of the ventilation holes 30a and 30b is too large, the electric resistance of the rotor winding 30 increases and the amount of heat generation increases. Further, there is a problem that the mechanical strength of the rotor winding 30 is reduced. In consideration of these problems, it is appropriate that the number of rows of the ventilation holes 30a and 30b is 2 to 4 rows. In the second embodiment, the ventilation holes 30a and 30b are arranged side by side in the radial direction of the rotor winding 18, but the same effect can be obtained even if the ventilation holes 30a and 30b are arranged in a staggered manner. .
