Abstract
In the method of the invention a laminated rotor is made using four different types of laminae, to form a stack of laminae into which molten conductor metal is poured to form cast conductors through aligned conductor slots in each of the laminae while transition laminae function to prevent the flow of metal into the coolant ducts of the stacked assembly. Practice of the method of the invention provides for making a plurality of laminated rotor assemblies, all of which utilize standard duct laminae configurations, but some of which have different configurations of conductor slots in either or both the main rotor laminae and the vent laminae used therein. In the method of the invention standardized sets of duct laminae are used in making a plurality of different rotor assemblies, which have, respectively, different sizes and shapes of conductor slots through the main rotor and/or vent laminae thereof.
