Abstract :
This article introduces the recent technological progress of manufacturing copper rotors through die-casting techniques, which provides a simple and practical means for large-scale economical production of efficient and ultra-efficient induction motors. It also illustrates examples of using cast copper rotors to manufacture high efficient single-phase motors as well as high efficient motors at IE3 and IE4 efficiency levels and analyzes the technical characteristics of cast copper rotor motors.
