This paper presents the results of wideband behavioral modeling of an induction machine (IM). The proposed solution enables modeling the IM differential- and common-mode impedance for a frequency range from 1 kHz to 10 MHz. Methods of parameter extraction are derived from the measured IM impedances. The developed models of 1.5 kW and 7.5 kW induction machines are designed using the Saber Sketch scheme editor and simulated in the SABER simulator. Modeling validation is based on prediction of electromagnetic interference (EMI) emissions of common-mode and differential-mode current spectra of experimental inverter-fed IM drives.
