ABSTRACT:
A laminated rotor for a dynamoelectric machine is formed by stacking a plurality of sets of punched laminae on one another to define axial coolant passageways, radial vents and coolant ducts and axial conductor-receiving slots through the assembled rotor. Each of the sets of laminae include a group of main rotor laminae, a group of vent laminae, a group of duct laminae and a transition lamina positioned between the vent laminae and duct laminae. In addition, a transition lamina is positioned between each set of stacked laminae thereby to arrange one transition lamina on opposite sides of each group of duct laminae, to effectively block molten metal from flowing out of the conductor slots into the coolant ducts of the duct laminae.
