“…The interaction between the spatial harmonics of MMF and the rotor geometry causes considerable torque ripples in SynRMs [54]. High torque ripples and as a consequence, the acoustic noise of these motors, have become a challenge, which persuaded considerable effort to cover this drawback in both design and control aspects [5,[55][56][57][58][59]. Some research works address the reduction of the torque ripples through optimization of the rotor structure [60,61].…”

“…This study shows that starting from the acquisition of the materials, through manufacturing, transporting, and marketing, SynRMs are competitive at the usage stage, and efficient at the recycling phase. Lack of rare-earth materials, low cost, comparable constant-power speed range, maximum torque per ampere, and efficiency of SynRMs, in particular, permanent magnet (PM)-assisted ones (PMSynRM), have made these motors an interesting choice in traction [2,3] and more-electrical aircraft applications [4][5][6]. Besides, the need for highly efficient motors in centrifugal machines, conveyor systems, fans and pumps, cranes, compressors, elevators, crushers, and general machine building (winders, extruders, and servo pumps) can be met by SynRM [7][8][9][10].…”

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.

“…In summary, the research on electromagnetic vibration and noise reduction methods of permanent magnet synchronous motors is mainly focused on improving the pole-slot matching, changing the pole arc coefficient, optimizing the structure of the stator tooth tip [15][16][17], as well as the rotor slanted pole [18], later active noise control methods [19,20], etc. As for the influence of the rotor slit structure on the electromagnetic vibration and noise of permanent magnet synchronous motors, there is little research currently.…”

The electromagnetic vibration noise level of a permanent magnet synchronous motor (PMSM) directly affects the Noise, Vibration, and Harshness (NVH) performance of an electric vehicle. Taking a PMSM for electric vehicle driving as an example, the electromagnetic noise characteristics were studied by combining ANSYS Workbench multi-physical field finite element analysis platform. The electromagnetic vibration force of the stator teeth of the motor is the main source of electromagnetic noise. The magnetic field of the motor can be optimized by changing the slot structure of the motor rotor, so as to improve the electromagnetic vibration force of the stator teeth and reduce the electromagnetic vibration noise of the motor. In order to optimize the magnetic field, three different rotor slot structures are proposed. The most suitable slot structure is found by comparing and analyzing the magnetic field, noise field, and electromagnetic force with the structure before optimization. By comparing the results before and after optimization, it can be seen that the optimized motor can effectively reduce the vibration noise of the motor and ensure the electromagnetic performance of the motor.

“…An optimized machine with magnets and minimizing the PM quantity can have improved machine performance in comparison to its counterpart interior and surface permanent magnet machines [7]. Numerus research papers have been published in optimization of SynRM and optimization of PMs, but optimization of PMSynRM as a whole object is never attempted due to the complication [10,[20][21][22][23][24][25][26]. Optimization process automatically vary the flux barrier dimensions.…”

CONTENTS 1. Introduction 2. Analysis of SynRM 3. Conclusion References Abstract-This paper presents the characteristics of permanent magnets in a synchronous reluctance machine by employing analytical and finite element methods. Four possible designs are studied and their characteristics are compared against a base synchronous reluctance machine with linear barriers to reveal machine characteristics. Then, the paper proposes a novel optimization topology to optimize permanent magnet synchronous reluctance machine as a single object for better machine performance. An explicit investigation is conducted to reveal the operational behavior of the machine such as torque, power factor and torque ripples with various machine parameters and compares them with the base design. The study reveals that permanent magnet synchronous reluctance machine can be optimized to have significantly high-power factor and torque with acceptable torque ripples.
