Modeling iron, mechanical and rotor copper losses in induction machine with the design of experiments

Abstract

In the field of optimization of hybrid renewable energy systems, maximum power extraction is still an important issue. For simulation purposes, accurate models are needed including all the losses in the different components of such systems. Among them, iron, mechanical and rotor copper losses in electrical machines are not always taken into account and are rather difficult to evaluate at variable speed and with PWM supply. This paper presents a practical and easy way for global loss modeling of an induction machine with the help of the Design of Experiments. This technique is simple since it requires a limited number of experiments and it provides the possibility to take into account several factors and their interactions.

The ECL Optimization and Experiment of HSPMSM with Improved Method

“…The computation of core loss and copper loss of coils has related mature method. The core loss [30][31][32][33][34][35] is calculated by loss coefficient method, while the copper loss [36][37][38][39][40][41][42][43] can be calculated by analysis method with AC effect considered. Besides, to measure the loss effectively and precisely, some improve modification of experiment has been proposed [44][45].…”
