Abstract

The work presents a fast and accurate empirical stray loss model for inverter fed three-phase induction motors (IMs). The model is intended to quantify the SL both at the design stage and, normal operation of the IM. The development of the model considers the variations of frequency, switching frequency and motor’s loading. Test data of 128 operating points of two training IMs are used to develop the model. The accuracy and prediction capability of the proposed model is presented with the measured SL values for 128 operating points of another set of two IMs of the same specifications and different geometries.
