摘要：
A method of improving the airflow through a low to medium speed salient pole dynamoelectric machine DEM is disclosed. The rotor rim on which the salient poles are mounted is shortened in comparison to prior art structures so that the ends of the salient poles (and the rotor windings) protrude a substantial distance beyond the edge of the rim. A stationary or rotating shield is placed in juxtaposed relationship with the rotating ends of the salient poles to provide an enclosure so that the protruding ends of the salient poles can function as a crude radial fan.
