A Piecewise Variable Parameter Model for Precise Analysis of Iron Losses in Induction Motors

This study proposes a two-term piecewise variable parameter model for precise prediction of iron losses in induction motors. In this model, two additional flux density terms reflect the non-linear magnetisation and the harmonic fields in the motors, and the main loss parameters are piecewisely variable with the magnitude and frequency of flux density, so that higher accuracy of iron loss predictio...
