The switched reluctance machine (SRM) has long been associated with high torque ripple as well as with producing excessive levels of audible noise. The correlation between torque ripple and acoustic noise has been subject to debate over the past decade. While there is no strong consensus, one perspective is that the correlation is weak at best, while the other presumes that a machine with high torque ripple is inherently noisy. This paper neither supports nor refutes these historical perspectives of the SRM. Rather, it presents evidence of multiple factors that affect torque ripple and acoustic noise. This evidence supports both views to varying degrees and has been collected experimentally from an SRM developed for a hybrid vehicle starter-alternator application.
