The usage of switched reluctance machines (SRMs) in acoustically critical applications like vehicles requires low noise emissions. This paper gives a brief introduction to noise development in SRMs with a special focus on the influence of the radial force. Based on this analysis in the time and the frequency domain, several noise reduction control strategies are presented and investigated for their effectiveness using simulation techniques and measurements. One of them is a new approach for partial load operation applying a single current pulse close to the unaligned position.
