TLDR
In this article, the results of an extensive study into the production of acoustic noise and vibration in the switched reluctance motor drive have been presented, and the results can be used to derive control laws for the power electronic controller to reduce the acoustic noises and vibration produced by the motor.
Abstract: 
This paper describes the results of an extensive study into the production of acoustic noise and vibration in the switched reluctance motor drive. Time domain analysis has been used to draw conclusions about the effects of changing the operating parameters of the power electronic controller on the vibration and acoustic noise. Experimental results have been taken from a four phase switched reluctance motor drive with one, two or four phase excitation. The results of this time domain study reveal important information which would not be apparent from frequency spectra. The results can be used to derive control laws for the power electronic controller to reduce the acoustic noise and vibration produced by the motor.

Vibration modes and acoustic noise in a four-phase switched reluctance motor

R.S. Colby, +2 more
TL;DR: In this article, structural finite element analysis is used to compute the natural vibration modes and frequencies of a four-phase, 8/6 SRM, and an approximate formula is derived to predict the frequency of the fundamental vibration mode in terms of lamination dimensions and material properties.
