Abstract
Improved cooling is provided for the end regions of the stator cores of large dynamoelectric machines where substantial losses result from the presence of axial magnetic flux. Additional cooling is provided in the tooth portion of the end regions of the core by means of axial vents in the slots for flow of coolant gas between the winding conductors and the slot walls, thus cooling the teeth and reducing excessive heating, while the heated slot wall is spaced from the winding insulation and direct contact is prevented.
