The use of aluminum in fabricated cage windings of large induction motors has been explored, and it was found that aluminum and its alloys present a viable alternative to copper and its alloys. This paper enumerates the advantages and limitations of aluminum as a cage material, outlines the considerations necessary in the utilization of the material for this application, and summarizes the results of a testing program which demonstrated the adequacy of aluminum alloy cages in full scale machines.
