Abstract :
The new model has hysteresis loss coefficients variable with frequency and a combined coefficient for eddy-current and excess losses that is variable with induction. The described mathematical algorithm employed for identifying the coefficients is based on a minimum of 15 measured curves, covering frequencies between 20 Hz and 2 kHz and inductions from 0.05T up to 2T. Over the entire range, the errors of the proposed model are considerably lower than those of the conventional model. Examples of application to electrical machine analysis are also included
