“…This comparison is verified using an appropriate transient FEM model built in Ansys Electronics simulation software. The transient FEM model, including the SRM geometry, materials, a winding and magnetic circuit, boundary conditions, a mesh, and an external supply circuit in the form of AHBC is defined according to [25,27,28]. The specific core losses at different frequencies and flux densities for the silicon steel sheets used (M350-50A) are shown in Figure 4.…”

To accurately predict motor performance, considering the effects of core losses is of great importance, especially at speeds much higher than the base where the core losses represent a considerable portion of the total drive losses. Neglecting the effects of core losses leads to an error in the switched reluctance motor (SRM) performance prediction. In this study, a previously developed non-linear SRM model with multiphase coupling is extended by considering the instantaneous effects of core losses on the SRM performance. Using the new model, the nature of these effects is determined. A comparison of the simulation results of the proposed, basic, and finite element method (FEM) model confirms the importance of considering the effects of core losses on motor performance. Besides the FEM model, the accuracy of the proposed model is verified by experiments.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Permanent magnet synchronous motors, and especially the interior permanent magnet topology, are extensively selected for automotive applications as they offer high torque density and efficiency and a wide-flux weakening range [6][7][8]. Induction machines (IMs) constitute a viable choice due to their lower cost, robustness, high overload capability and lack of rare-earth materials [9][10][11]. However, they inherently exhibit poorer flux weakening behavior in terms of reduced high-speed torque and power, linked to high values of leakage inductance.…”

Design Aspects and Performance Evaluation of Pole-Phase Changing Induction Machines

Pole-phase changing induction machines (IMs) offer the capability to extend the torque-speed envelope compared to their fixed pole-phase counterparts. Dynamic pole-changing can achieve higher torque levels at lower speeds, utilizing higher pole numbers, and extended flux-weakening range with lower pole-number operations. This paper investigates the design impact on the optimum pole-phase changing behavior and respective split of the operating region to different pole-phase operations. Additionally, the improvement in terms of the overall torque per ampere capability and efficiency is illustrated. For the purposes of the analysis, two different IMs with wound independently-controlled stator coils (WICSC) and different original pole numbers are evaluated in an effort to quantify the extent of the benefits of pole-phase changing. These geometries correspond to machines that were originally designed with 2- and 6 magnetic poles, respectively. It is shown that, in the case of the original 2-pole WICSC machine, shifting to a higher pole number is notably beneficial in terms of efficiency in a significant part of the operating region, whereas in the original 6-pole, both higher and lower pole numbers significantly enhance the overall torque capability and efficiency. The results highlight the notable benefits of pole-phase changing IMs and offer deep insight towards the derivation of standard design guidelines for these machines.
