Analysis of Induction Motor with die cast rotor

Abstract: This paper presents the choice between the utilizing a lower cost die cast or fabricated aluminium rotor versus the more expensive copper bar rotor. In industrialized countries Induction motors account for approximately 50% of the overall electricity use. In every field whether it is agricultural sector or the economical sector. The power consumption by a.c motors is quite enough. On an average the cost of energy consumed by the motor is nearly 60-100 times the initial cost of the motor. So the efficiency of motor is of great importance whether during the selection or during the operation. Small increase in motor efficiency can make an overall big difference between the total electricity consumption. Using copper in place of aluminium would result in a motor efficiency higher than that of the original aluminium-based motor. Consequently, the motor can then be scaled down in size, thus decreasing the individual costs of many other steps in the manufacturing process and theoretically lowering motor cost as a whole. This paper discusses the implementation of Die cast rotors, Motor efficiency, and increasing the prospect of the country by using DCR technology.
