The question is about the asynchronous machine and saturation effect. Does anyone know how the coeffiecients of the fifth degree polynomial function are calculated through the measurements Vll_noload, Il_noload?

use curve fitting toolbox to determined coefficients of nonlinear characteristic.

if i use x->Ill_noload and y->Vll_noload will i take the right coeffiecients for the saturation effect block?
