The equivalent circuit has been used to calculate performance of induction motors. In this calculation, the primary and secondary leakage reactance correspond to half the reactance determined by the locked rotor test. The present paper investigates the most suitable search coil for determining the stator leakage reactance that accounts for the current that flows in the end ring. This coil was applied to two induction motors in order to determine stator leakage reactance. One of the sample motors was equipped with a squirrel-cage rotor with semi-closed slots and end rings. In this motor, the core stack length of this rotor was equal to that of the stator. The other motor was equipped with a squirrel-cage rotor with closed slots and end rings. The core stack length of this rotor was also equal to that of the stator. Two equivalent circuits were used in the simulation in order to determine stator leakage reactance during asynchronous operation. When the leakage flux due to the current that flows in the end ring is accounted for, the results of simulation are in good agreement with those of the search coil test. Thus, leakage flux due to end ring current does contribute to overall stator leakage reactance.
