Abstract
In this paper, an accurate high-frequency model of induction motor is presented. The proposed model allows analyzation at the same time both the high-frequency phenomena up to some megahertz due to the static supply and the 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.
