  • Dynamoelectric machine having fluid cooling of back iron and end turns
    Patent number: 5363002
    Abstract: A dynamoelectric machine such as a generator has stator winding end turns which extend beyond the ends of a stator core of the apparatus. The end turns are cooled by conveying fluid coolant from back iron cooling grooves to fluid coolant exit ports through which the coolant is distributed onto the end turns. The cooling arrangement eliminates the need for separate spray rings or nozzles and is low in cost and easy to clean.
