“…For the sake of different purposes, such as design [26], control [73], fault diagnosing [74,75], thermal analysis [76], loss determination [77], motor parameter calculation [52], stability analysis [78], and efficiency improvements [79], modeling is an inseparable part of many studies in motor drive areas. In the modeling of SynRM, parameters' estimation preciseness, the computation time of the parameter determination, and some factors for different motor operation areas, linearity and nonlinearity of the model have been crucial criteria to consider.…”

Recent studies show that synchronous reluctance motors (SynRMs) present promising technologies. As a result, research on trending SynRMs drive systems has expanded. This work disseminates the recent developments of design, modeling, and more specifically, control of these motors. Firstly, a brief study of the dominant motor technologies compared to SynRMs is carried out. Secondly, the most prominent motor control methods are studied and classified, which can come in handy for researchers and industries to opt for a proper control method for motor drive systems. Finally, the control strategies for different speed regions of SynRM are studied and the transitions between trajectories are analyzed.

“…References [15,16] calculated the motor Q-axis inductance and D-axis and gave the motor magnetic circuit distribution method. The comparison of the synchronous reluctance machine's and the permanent Magnet-Assisted synchronous reluctance machine's performance characteristics in references [17,18] show that the PMA-SynRM motor has a higher efficiency, power factor, and torque density. However, it also increases the material cost and manufacturing difficulty.…”

This paper proposes a novel modular permanent magnet-assisted synchronous reluctance motor (MPMA-SynRM) structure. The rotor is composed of two types of rotor modules that are axially combined. This article analyses and explains the combined angle of the axial assembly of different rotor modules. The MPMA-SynRM rotor module is optimized using a differential evolution algorithm and the MPMA-SynRM space vector diagram is established to give the torque calculation an analytical expression. Whether there is axial magnetic isolation between different rotors is analysed, and various segment numbers, pole arc coefficients, and length ratios are used for different rotor modules to affect the electromagnetic influence of the MPMA-SynRM's cogging torque. Detailed analyses of the MPMA-SynRM loss, efficiency, and permanent magnet demagnetization state are given. The no-load back EMF, power factor, efficiency, eddy current loss, and cogging torque of the MPMA-SynRM with traditional Nd-Fe-B permanent magnet motors and permanent magnet auxiliary synchronous reluctance motors are compared, and a prototype is made to prove the performance of this motor.

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.
