다이캐스트 구리 모터 로터: 구리와 알루미늄 모터 테스트 비교 결과 Edwin F. BrushJr.John G. CowieDale T. PetersDarryl J. Van Son Abstract Motor manufacturers have long realized that because the electrical conductivity of copper is nearly 60% higher than that of aluminum, substituting copper for aluminum in the squirrel cage of the induction motor would markedly increase the electrical energy efficiency of the machine. Most
구리 다이캐스팅으로 IE4 효율 수준을 달성하기 위한 15kW, 2극 유도 전동기의 설계 최적화 Abstract This paper describes the design and simulation of 15 kW, 2 pole, 50 Hz, three phase induction motor to achieve IE4 efficiency level as defined by the International Electrotechnical Commission (IEC). For achieving higher efficiency, the motor is designed, optimized and
Daniel Liang, Xu Yang, Jiabin Yu, Victor Zhou Abstract This paper introduces the recent technological progress in China on the manufacture of die cast Copper Motor Rotors (CMR) for induction motors. This manufacturing process provides a simple and practical means for large-scale economical production of high-efficiency induction motors. Rotor die casting obstacles/solutions are presented along

1. Overview: 2. Research Background: In metalcasting, cores are essential components utilized to create internal geometries and voids within cast products. The selection and performance of cores are significantly influenced by the casting technique employed, ranging from gravity casting to high pressure die casting. As component designs become increasingly complex and environmental regulations more stringent,
