Induction motor high frequency model

Abstract

In this paper, an accurate high frequency model of an induction motor is presented. The proposed model allows analysis, at the same time, of both high frequency phenomena up to some MHz due to the static supply, and low frequency phenomena usually analyzed by means of the dq motor model. The high frequency model has been obtained by means of a frequency and time domain analysis and has been verified on a wide spread of induction motors starting from 4 up to 55 kW. The proposed model can be used to evaluate the high frequency leakage currents, which are the cause of electromagnetic interference to electronic and electric equipment.
