“…Vibration dampers are also applied where the fuel rail is connected to the cylinder head and the transmission is connected to the engine block [70]. Vibration dampers with a smaller cross section applied axially between the stator poles and housing can reduce the radial acceleration of the housing surface by 10 folds [71]. Poor thermal conductivity of VEMs should also be considered when they are applied between the stator and housing for vibration damping [72].…”

“…Visco-Elastic Materials (VEMs) can be economical and various grades of VEM cater to a wide range of frequency requirements [151]. VEMs can be applied between the stator and housing [71] and between the housing and endcaps as vibration dampers. Free Layer Dampers (FLDs) can be applied to the endcaps as they are relatively thinner than the housing.…”

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.
