Abstract
Improved cooling is provided for the end regions of the stator core of a large dynamoelectric machine. For this purpose, a solid rigid vent plate is placed in contact with the finger plate at each end of the core. The vent plates are non-magnetic plates of the same configuration as the core laminations and have radial grooves in at least one surface. Coolant gas flows through the grooves to directly cool the finger plate and the end laminations of the stator core.
