Abstract

This paper proposed an efficient approach for predicting electromagnetic interference emission of motor and its drive system under field-circuit and transmission line(TL) coupling.As the common mode interference circuit is the main source of electromagnetic emission

its propagation path is analyzed.On this basis

the key components' models in common mode interference conduction path are established

such as AC induction motor's equivalent circuit modell

drive system's inputs' and outputs' harness model of shielded cable and so on.Then

each part circuit model is connected according to the system's actual combination and the system's EMI prediction model is obtained.Finally

CST MWS and CST CS studio joint simulation method is used to analyze the proposed prediction model and the results are in good agreement with experiment measurement

which validate the accuracy of our proposed approach.
