Abstract
Disclosed is an alternating current dynamoelectric machine which has damper plates of low resistivity material over the ends of the stator's tooth region to prevent axial flux from entering the stator's core. This invention also provides for cooling of the damper plates by the inclusion of cooling ducts within the damper plates. The flow of cooling fluid through the ducts cools the damper plates and also the end region of the dynamoelectric machine.
