This paper presents methods to determine the operational impedance of rotating machines by Fourier transformation of the voltage and current measured when a step (or pulse) voltage is applied to the two stator winding terminals. These standstill tests using a small‐capacity DC power supply unit are tentatively termed DC testing methods. We also describe in detail the case using a DC power source with ripple and the case in which a step (or pulse) voltage is applied with current flowing. These methods are applied to a 5.5‐kW squirrel‐cage induction motor having semiclosed rotor slots. The validity of the proposed prediction methods is demonstrated by comparing the calculated and measured speed characteristics of the tested induction machine. © 2004 Wiley Periodicals, Inc.
