“…Kotegawa T proposed a stator structure with trapezoidal tips and conical yokes, and the experimental results show that this structure reduces the maximum displacement of the stator surface by 42% and achieves vibration and noise reduction [11] . Most related studies have shown that grooving in the stator yoke has a better vibration and noise reduction effect than grooving in the stator tooth [12] . Although the grooving of the stator and rotor teeth can reduce the vibration, the torque is mostly lost.…”

Switched reluctance motors have many advantages over traditional adjustable speed drives, but vibration and noise problems are particularly acute due to their double salient pole construction and switching power supply. Therefore, taking effective measures and means to optimize the switched reluctance motor system to improve vibration and noise has important theoretical and practical significance for its promotion and application. In order to provide a clear solution to the problem of SRM vibration and noise reduction, this paper introduces the sources and theoretical research status of vibration and noise of switched reluctance motors and focuses on a series of research methods to reduce vibration and noise of switched reluctance motors from the aspects of motor body structure, parameters, and control strategy technology.

“…Acoustic noise mitigation involves reducing the peak radial force [107] and shifting the structural resonance frequency of the stator away from the excitation frequencies [109]. The above can be met through: (i) Design strategies (magnetic design of the stator and rotor) [107–120]. (ii) Commutation strategies [121–141].…”

“…Similarly, the radial force was found to decrease with the introduction of windows in both the stator and rotor teeth [116], double‐stator configuration [117] and mutual coupling in between SRM phases [118, 119]. A major reduction in the radial force was observed for increasing the teeth number in the stator and rotor by 26 times [120].…”

Some key features to be satisfied by electric motors catering a wide range of applications are high specific power, lower manufacturing cost, rugged construction, and fault‐tolerant operation. Switched reluctance motor is one such motor technology satisfying all the above requirements and is an emerging competitor to the induction and permanent magnet motors in domestic, industrial and electric vehicle applications. The present‐day research on this motor is moving towards improving efficiency at lower speeds, power density, and the torque density. Certain challenges in achieving the same are (a) minimising the losses, (b) mitigation of torque ripple, noise, and vibration, and (c) material advancements. A review based on the estimation and mitigation techniques of each of these over the past three to four decades has been dealt with in this study. The salient features and results in each section provide a clear understanding of how each of these challenges can be overcome in the aspect of design and control strategies.
