Abstract :
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. Design modifications to better utilize copper in the rotor and resulting motor performance for two other industrial motors are then reported
