Induction motor is the most widely used to obtain the driving force in the industrial site. Induction motor is generally applied to the constant speed operation. Induction motor generates a high current at startup. So analysis for both steady state operation and start-up transient is required. In most cases, an equivalent circuit is used for the characteristics analysis of the induction motor. In this study, the two programs are applied to analyze for the rated speed as well as entire speed range. We confirmed that calculation results of the two programs are similar to each other.
