This paper adds to the growing body of data showing improved efficiency and cooler running temperatures for copper rotor motors. Test data for motors where copper has simply been substituted for aluminum with no change in design are presented for a series of motors built in India for pumping water for agriculture and two industrial motors are described.(More)

generally focused on the common aluminum-, zinc-and magnesium-based die casting alloys. This report differs in that it deals with pressure die casting of a relatively high melting metal, pure copper. Short mold life is the limiting factor in achieving a cost effective die casting operation for high melting metals and alloys. This study, where the primary(More)
