Influence of non-ideal magnetic core effects on the experimental determination of the magnetic characteristics of a switched reluctance motor

Abstract

This paper proposes an alternative method to obtain the experimental determination of the flux Iinkage current-position characteristics of a switched reluctance motor. Simulations are performed using different models of a phase of the motor. The results are compared with experimental measurements showing the influence of non-ideal effects associated with the magnetic core on determining the flux current-position characteristics.

Non‐linear model of the switched reluctance motor with included core losses’ effects

“…However, since the analytical equations for prediction fluxes in [13] are not accurate enough, the use of the proposed method is limited. An assessment of the average value of the equivalent core-loss resistance in steady state is presented in [14][15][16]. However, this is not acceptable for dynamic modelling, according to [17], since the equivalent core-loss resistance in these models does not depend on the magnetising current.…”

Energy Transformations in a Self-Excited Switched Reluctance Generator

“…If generation is performed using constant power, as in the case of hydropower turbines, electronically-controlled loads are used as a voltage-stabilizing element [12,13]. These generators are based on a fourth-degree model, whereas a switching reluctance machine (SRM) has a second-degree model for each phase [14,15]. Since the phase-to-phase coupling is lower, the model is less complex.…”
