Today, the majority of the commercial electrified vehicles use Interior Permanent Magnet Motors (IPMSMs) for propulsion. An IPMSM can deliver high starting torque and high efficiency in the low-and medium-speed operation, which makes it attractive for propulsion applications. However, IPMSMs generally utilize rare-earth permanent magnets and there are growing concerns about the price volatility and supply chain of these materials. Switched Reluctance Motors (SRMs) can potentially replace IPMSMs in various applications including propulsion. An SRM has a simple and low-cost construction, and it can provide reliable operation at high-speed and high-temperature conditions. Compared to IPMSMs, SRMs radiate considerably higher acoustic noise, which have historically hindered their widespread acceptance. Various approaches to mitigate acoustic noise and vibration at the source level have already been explored in the literarture by improving the electromagnetic design and current control. This paper explores multiple noise and vibration mitigation methods that can be applied at the transmission stage. First, the noise comparison between the Internal Combustion Engine (ICE) and SRMs is discussed, and then the methods used for ICEs are presented for their applicability to SRMs.

Summary In comparison to one‐layer switched reluctance motor (SRM), a multi‐layer SRM is able to produce much larger output power and it can be considered as a good candidate for high‐power electric machine. For a multi‐layer SRM, different layers have the same performances and they are completely independent from electromagnetic point of view. Therefore, analysis of one layer can be only carried out to determine the electromagnetic characteristics of the multi‐layer SRM. In the present paper, a fast and simple magnetic equivalent circuit (MEC) model is introduced for one‐layer SRM and it is then used for performance prediction of the multi‐layer SRM. Due to high torque ripple of the SRM, a simple solution is suggested for different types of the multi‐layer SRM by which torque ripple of this motor can be reduced significantly. To evaluate the done modeling and the suggested torque ripple method, simulation results are presented for a typical multi‐layer 8/6 SRM.
