“…Due to the doubly salient construction and fundamental excitation principles, the majority of the flux in SRM is in the radial direction. Although the torque ripple caused by fluctuations of F rt during motor excitation and demagnetization may also induce tangential vibration, it can be neglected compared with radial vibration, which has been also verified by the works of several researchers [1,18,26]. For instance, Cameron et al [18] designed a series of experiments to investigate the vibration in SRM, and the experimental results showed that radial vibration of the stator frame caused by radial electromagnetic forces is the dominant source of vibration in SRM.…”

Currently, vibration has been one crucial factor hindering the application of switched reluctance motor (SRM). Hence, it is of crucial importance to predict and suppress this undesirable vibration. This paper proposes a multi-physics analysis-based vibration prediction approach for SRM. It consists of three modules: digital controller and drive circuit module, electromagnetic field module, and mechanical module. In the mechanical module, it not only includes the influence of the stator, but also fully considers the influence of rotor, end cover, bearing, and other components of the motor on the system modal. Moreover, the vibration data under different control strategies areis obtained in real time, and data dynamic interaction between the three segments can be also be achieved. By combining the electromagnetic forces and the system structure modal, the vibration of SRM can be predicted. Finally, the effectiveness of the proposed method was verified on a 12/8 poles, 1.5KW SRM drive system test bench. The results demonstrate that the modal simulation method based on static pre-calculation achieves high accuracy, and the vibration spectrums predicted by the proposed method shows good agreement with the experimental results.

“…Switched reluctance motors have drawn increasing attention for EV application, not only because of their excellent performance, simple structure, low cost, robustness, and fault tolerance, but also because they do not employ rare-earth materials, which means SRM do not suffer the disadvantages of high price and environmental damage involved with mineral extraction and refining [138,139]. Although there are many advantages of SRMs compared to other traditional AC machines, they have an obvious disadvantage-acoustic noise-which results from radial vibration and torque ripple.…”

“…According to literature, the instantaneous torque equation of SRMs can be obtained based on the phase inductances (self and mutual) and phase currents [2] [3] [25]. Assuming the magnetic saturation can be neglected, the on-load torque of an m-phase SRM is given by (1) where m represents the phase number, . is a inductance matrix.…”

“…In addition, without permanent magnets or field windings on the rotor, they are particularly suitable for harsh environment operations such as high speed and high temperature. Due to these significant advantages, SRMs have attracted increasing interest in electric vehicles, aerospace and other safety-critical applications [1]- [2]. However, the doubly salient structure together with the special rectangular wave current supply cause high torque ripple, high vibrations and acoustic noise compared with other types of machines.…”

Such machines are similar to switched reluctance machines but supplied with sinewave currents. The investigations in this paper are as follows: first, a general analytical torque model based on Fourier Series analysis of inductances has been built for machines with different phase numbers, slot/pole number combinations and also winding configurations. The instantaneous torque for DS-SRMs with any given phase number can then be accurately predicted. Using such model, contribution of each order inductance harmonic to torque can be investigated separately. It is found that the torque ripple frequency of the DS-SRM only depends on phase number. For example, for a m-phase machine, there will be m×k th order torque ripple if , where m is phase number and k is a natural number. This study also explains why certain phase numbers inherently produce lower torque ripple than others. The findings in this paper provide a future direction for potential torque ripple reduction methods either from machine design or advanced control. The simulations have been validated by experiments using a 6-phase DS-SRMs.Index Terms-Doubly-salient, multiphase machine, synchronous reluctance machine, torque harmonic.
