Core Loss Estimation for an Inverter-Fed Induction Motor With More Accurate Realisation of Material Non-Linearity and Impact of Hysteresis Minor Loops

The work presents a fast and accurate core loss evaluation method for inverter-fed induction machines. proposed takes into account the influence of time variation magnetic permeability on eddy current loss. Furthermore, an approach to precisely evaluate hysteresis results obtained from are compared with existing methods 1.5 kW inverter-driven motor. shows sufficiently high accuracy reduced complexity implementation-time wide range inverter switching frequency motor’s loading.
