Abstract :
A high frequency (HF) modeling method of low-voltage DC motor impedance is proposed. The model suggested is dedicated to the estimation of conducted electromagnetic interferences (EMI) within the car body and combines the advantages of both an analytical and a behavioral approach. It can simulate the motorpsilas complex impedance from the continuous up to a frequency of approximately 1 GHz. Moreover, this model takes into account the skin effect in the winding and the eddy current effect in the laminated iron core. A parametric identification method was developed in order to improve the model.
