ABSTRACT:
A plurality of salient poles and a stator are adapted to be cooled only by cooling gas which is passed through a plurality of fluid passageways formed in a yoke of a rotor. By the arrangement that all the cooling gas discharged through the fluid passageways is used for cooling the rotor and the stator, cooling efficiency can be increased due to enhanced flow characteristics of the cooling gas.
