Abstract:The paper presents an advanced quasi-FEA technique on the iron losses prediction using Bertotti's iron loss separation models, in which a curve fitting is taken into account for coefficients calculation of each model. Moreover, the skin effect and saturation consideration are applied in order to check the accuracy through the relative error distribution in the frequency domain of each model from low up to high frequencies 50 to 700 (Hz). Additionally, this comparative study presents a torquespeed-flux density … Show more
“…At this stage, the iron losses as function of temperature is calculated using Bertotti's iron loss separation models [29][30], in which skin effect has been accounted through following equation. The calculation results have been reported in Table 1.…”
