Electric motors using copper rotors are significantly more energyRecent
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
