SPIDER BAFFLE FOR DOUBLE END VENTILATION IN DYNAMOELECTRIC MACHINE ABSTRACT OF THE DISCLOSURE In a double end ventilation dynamoelectric machine one side often runs at a higher temperature than the other side because the amount of air entering the rotor spider from each end is not equal. In addition there is turbulence and interaction where the two air streams meet. A vertical baffle is mounted between the rotor spider arms at an axial position to provide equal air flow from each end. This tends to equalize cooling as well as reduce the instability of the air. The sides of the baffle may be shaped to further improve flow and reduce pressure drop.
