Behavioral high-frequency modeling of electrical motors

Reliable simulations of electromagnetic interference in motor drive power electronic systems ask for accurate high-frequency motor models. A methodology for creating frequency dependent behavioral circuit models of ac electrical motors is presented in this paper. It is based on the rational function fitting of measured motor network parameters. Stable, causal, and passive equivalent circuits are obtained and their accuracy verified by comparing the simulation results with frequency domain common- and differential-mode measurements.
