Accuracy Analysis Of Rotor Frequency Calculation For Induction Motor Drive

Abstract

This paper deals with the accuracy analysis of rotor frequency calculations for an analyticalformula of the optimal linkage flux. First, an equivalent circuit of the induction machine and a loss modelare described. Furthermore, the calculation of the rotor frequency is performed for two cases, which arecompared. The results show that the rotor frequency can be calculated in a simplified form without a largedifference in accuracy.
