In order to speculate motor performance with high precision, it is important to understand correctly motor parameters, such as reactance, in an actual operation state. This paper presents a study of three reactance evaluation methods: Dalton-Cameron method, the method applying direct magnetic field and the method considering cross-magnetizing reactance. Dalton-Cameron method and the method applying direct magnetic field are superior in simplicity of measurement. But the reactance under saturated magnetic field could not be calculated correctly by two former methods, because magnetic saturation in the actual operation state is not taken into consideration. In this paper, it is indicated that the results calculated by the two former methods have errors to the measured results, and that the reactance should be calculated by the method considering cross-magnetizing reactance, when we treat the machine that has a complicated magnetic circuit.
