Soby T. Varghese; K. R. Rajagopal; Bhim Singh Abstract t is well known in the market that the copper rotor motor can give good efficiency at par with the new era motors, and can handle higher temperatures to qualify for electric vehicle application. Being a heavy metal, die-cast copper rotor manufacturing needs absolute care for faithful rotor

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.

ABSTRACT This thesis describes, in a manufacturing context, the development of new waterbased core technology for light alloys. Cores used for steel casting are made from fused silica and are removed using hot sodium hydroxide under refluxing (pressurising hot acids). However, aluminium and other light alloys are attacked by sodium hydroxide. Currently there is no
