Abstract
In a dynamoelectric machine, stacked turns are provided with registering openings for the flow of a cooling medium from a subslot radially within the rotor in a direction radially outwardly to cool the turns. Turbulators are provided in each of the turns to enhance the turbulent flow of the cooling medium which enhances the heat transfer between the heated turn and the cooling medium. The turbulators are formed by a coining operation after the openings are punched through the turn to form an inwardly directed rib effecting turbulent flow in that region and enhanced cooling effects.
