A various types of rotor stampings (laminations) 1 can be die cast using copper instead of using aluminum; and making die cast copper rotors which will save electrical energy of motor due to higher conductivity of copper which is near double than conductivity of aluminum. To Invent a method for die cast copper in rotor stampings (laminations) and make Rotor according to different types and desired size’s. A method of making economical affordable die cast copper rotors. A method of melting copper for die casting one can allow minimum metal oxidization. Method of making economical suitable dies which can reduce the overall cost of rotor making. Drawing: 10 Sheets Total Pages: 28. Fig. Nil
