Abstract

This paper presents the finite element method for the calculation of open‐circuit characteristic of a squirrel cage machine with saturated core. The flux linkage with the stator winding and the winding inductances have been calculated using the edge element method. The calculations show that the equivalent inductance of a balanced three‐phase no‐loaded induction machine with saturated core may be defined like a quadrature‐axis inductance in synchronous machine. The algorithm of this inductance calculation has been proposed. The equivalent inductances have been used in the calculation of electromotive force. The results obtained from numerical calculations have been compared with the measured results.
