This paper presents a unified predictive modeling for common-mode (CM) and differential-mode (DM) impedance estimation of a Permanent Magnet Synchronous Motor (PMSM). This methodology combines 2D Finite Element modeling and generated lumped parameter circuit in Spice environment. It is then used to determine the consequences of design choices and evaluate the importance of controlling the winding process in the PMSM manufacturing. By doing so and by changing parts of the PMSM design, the overall high frequency response of the system with regards to input parameters can help in satisfying EMC high frequency constraints (between 1 kHz and 10 MHz).
