One of the ways to improve the efficiency of an induction motor without increasing of frame size is to change the rotor cage material from aluminum to copper. Thanks to such an operation, the rotor cage resistance is decreased by about 40% and rotor's resistance losses are also significantly decreased. In consequence the efficiency of induction motor is higher by 1 to a few percent (depending on motor size and power). The copper rotor cages have been manufactured for many years using prefabricated copper bars. Such a construction of rotor cage is relatively expensive in manufacturing, and this is the main reason why this construction is usually used only in high power induction motors. Low and middle power induction motors have, in more cases, the rotor cage manufactured as an aluminum casting because of simple and inexpensive manufacturing technology. Since a few years in foreign technical papers and books an increased interest in casting of rotor cages with copper can be observed. In this paper the advantages and benefits of using rotor cages with copper casting are presented and discussed on an example of 4 pole induction motor with frame size 132.
