Parameter identification of a finite element based model of wound rotor induction machines

Purpose - The aim of the paper is to explain and clarify the pre-processing for a finite element based wound rotor induction machine model. Design/methodology/approach - The paper presents two algorithms. The first one speeds up the FE-simulations by changing the input parameter permutation scheme only. The second algorithm speeds up the quint-cubic spline parameter calculation by utilizing the continuity conditions between adjacent segments. Findings - The paper provides comparisons of the calculation cost to show the advantages of the presented algorithms. Originality/value - The algorithms explained in this paper allow a practical application of the finite element based model approach for a wound rotor induction machine. Therefore, this work completes the development of the finite element based wound rotor induction machine model.
