“…This observed variation can be explained in termsof the magnetic super exchange interaction which has a direct relationwith Curie temperature [13,22]. Further, the strength of ABinteraction, which is the interaction existing between the antiparallel uncompensated electron spin of A and B sublattices is the mostdominant [23]. This interaction is observed to decrease with Cusubstitution as indicated by the magnetization measurements thusaccounting for the fall in Curie temperature.…”

“…The main purpose of the rare earth free electric machines is to reach almost the same torque density as in commercially available neodymium PMSMs, without efficiency deterioration. Major part of these attempts is done for hybrid electric vehicle applications [20][21][22][23][24][25][26][27]. Common measures in order to increase the power density of PMSMs are high angular speeds [28], increase the number of pole pairs and increasing the tangential stress [29].…”

“…In [6,7], FSCW and integral slot distributed winding (ISDW) V-shape IPM motors are presented, investigating the effect of the PM geometry and the winding topology on the performance. The feasibility of a low cost ISDW ferrite-assisted synchronous reluctance machine has been evaluated in [8]. At last, different cooling systems of an FSCW spoke-type IPM motor are compared in [9].…”

“…All the topologies share a uniform airgap, provide a comparable performance and are good candidates for the FreedomCAR application. On the other hand, they do not achieve the most challenging specifications that are efficiency (even only electrical) >95% at a partial load (20% rated torque), at a high speed range and a line-to-line back EMF <600 V peak , respectively, at maximum speed [4][5][6][7][8][9][10].…”

In recent years, electric mobility is becoming a growing reality because of the increase of the oil demand and cost as well as the environmental effect of the conventional internal combustion engines. Since about a decade, in the USA, a publicprivate cooperative research initiative, called FreedomCAR (US Drive by mid 2012) has been working for developing high efficiency and cost competitive technologies for the electrification of private transport. This research presents the design and the comparison of two high performance, radial magnetisation, interior permanent magnets and synchronous motors, according to the FreedomCAR targets, equipped with different rotor shape geometries. The first is characterised by a nonuniform airgap, whereas the second presents a conventional rotor shape. Both the machines are equipped with the same stator and a fractional slot concentrated winding. This paper highlights the benefits for using a non-uniform airgap rotor design, especially concerning the efficiency, that represents the most difficult target to be satisfied.

“…Strong and rare-earth PMs like NdFeB and SmCo offer good performance. However, they are not recommended in some applications due to their high cost [8]. On the other side, the PM-assisted SynRM with non-rare-earth PMs can be considered an alternative for PM machines that use fewer PMs [7]- [11].…”

Optimized Design of Rotor Barriers in PM-Assisted Synchronous Reluctance Machines With Taguchi Method

et al. 2022

In recent years, PM-assisted synchronous reluctance machines simplicity, robustness, efficiency, and temperature capacity (SynRMs) make them a viable alternative in various applications. The poor power factor (PF) and high torque ripple are the main challenges of SynRMs, which necessitate robust optimization improving the mentioned demerits. However, the optimization algorithms usually rely on complex analytical models; in this paper, in order to optimize, the design of experiments with the Taguchi method has been used. Taguchi is a simple and effective optimization method and requires a small number of experiments and experience. Also, to select the best combination in multi-objective optimization, the TOPSIS method has been utilized to prioritize the optimal solutions. The proposed method is evaluated by finite element analysis (FEA).INDEX TERMS Permanent magnet (PM)-assisted synchronous reluctance machine (SynRM), multiobjective optimization, Taguchi method, finite element analysis (FEA), torque ripple.
