Fabricated aluminum rotor construction for induction motors

The selection of material for induction motor rotor conductors is an old question and has been the subject of numerous papers and other literature for many years. This paper presents a new process being used in the construction of aluminum conductor rotors and reviews rotor construction from a slightly different point of view. The comparison is viewed using simple engineering concepts to illustrate the value of fabricated aluminum construction. The results of this new process have been impressive, particularly for two-pole motors, making fabricated aluminum construction the designer's choice.<>
