“…Mechanical vibration and noise in electric motors have three main sources [5], [8], [10], [14] • Mechanical noise: originated by the mechanical components of the motor such as fasteners, rotating parts like bearings and shaft. Noise associated to rotor dynamics includes both lateral and torsional dynamics [15].…”

“…The complicated formulation and high computational time of the VWP method has led to wider adoption of the Maxwell stress tensor method [84]. However, the VWP method leads to more accurate results, while the MT method presents the additional difficulty in defining the integration path [10], [84]. A synthetic comparison between the two methods is reported in table II.…”

“…In order to conduct a modal analysis, the first step is to calculate the structure's eigenfrequencies and modes [106], the information obtained could be compared with analytical model results previously described. By the finite-element modal approach, it is possible to analyse the various motor components, this allows to study how geometric parameters affect electric motor characteristics [10]. This type of analysis is very important for the design and optimisation stages.…”

This paper provides an overview of current Noise Vibration and Harshness (NVH) challenges for the design of Permanent Magnet Synchronous Motors (PMSMs) for automotive applications. Particular attention is devoted to analytical and numerical methods utilized in NVH modelling. Electromagnetic force computation, motor structural modelling and acoustic emission calculation are reviewed focusing on NVH emissions. The literature reveals, as expected, that analytical methods are simpler than numerical ones, and are usually employed during the preliminary design stage. Numerical methods are adopted in the detailed design stage as the computational cost increases. PMSMs are selected for high performance and high efficiency motor drives, they are widely adopted in the actual transition to vehicle electrification. The paper provides guidelines for facing NVH design issues of PMSMs.
