“…The second time, the Wayne Kerr Precision Impedance Analyzers (6500B) was used to measure the CM mode impedance and phase angle of SMIP in therunning phase in the frequency range from 100 Hz to 30 MHz. Different high-frequency models for CM and DM characteristics have been suggested for the three-phase induction motors [45], electrical equivalent circuits or Lumped Parameter Models are the most advanced modeling approaches for capturing the behavior of electrical machines in high frequencies. These models may be created using various methods.…”

The Single-Phase Induction Motor (SPIM) has gained widespread adoption in various power applications. This article introduces a new study and analysis of SPIM, focusing on its high-frequency (HF) modeling within the conducted electromagnetic interference (EMI) frequency range of interest (150 kHz -30MHz). This research is crucial for ensuring electromagnetic compatibility (EMC), evaluating electromagnetic interference issues, optimizing machine design, and complying with EMC standards. To identify common-mode current propagation paths accurately, a precise impedance analyzer is required to determine the common-mode impedances models of the high-frequency motor. The article proposes an HF modeling method based on a genetic algorithm (GA), which offers the advantages of high accuracy, versatility, and fast simulation time. This approach effectively reproduces models, trends, and relationships observed in real data, indicating a high level of fidelity and reliability in its predictions. Case studies validate the efficiency of the proposed HF modeling method. These precise predictions of undesired HF phenomena provide valuable insights into identifying areas where parasitic currents may propagate in the motor and understanding the impact of each motor phase on the overall behavior of the motor's commonmode impedance.INDEX TERMS AC motor, common-mode (CM), EMC characterization, high-frequency.
