Abstract:

Inverter-fed Permanent Magnet Synchronous Machines （PMSMs） are subject to substantial current harmonic excitations， which critically affect their electromagnetic vibration and noise characteristics. The accurate modeling and efficient computation of these effects have emerged as key research focuses in recent years. While the conventional finite element method offers high precision， its complex implementation procedures and substantial computational costs limit its applicability， particularly during the early stages of motor development where rapid iteration is essential. Consequently， there is a pressing need for modeling and computational approaches that can achieve favorable balance between accuracy and efficiency in the analysis of electromagnetic vibration and noise in inverter-fed PMSMs. To address this issue， this paper presents a comprehensive review of the state-of-the-art modeling and computational techniques for electromagnetic vibration and noise analysis in inverter-fed PMSMs. The review systematically examines key factors such as current harmonic types， electromagnetic force generation， structural modal behavior， vibration responses， and radiated noise. For each aspect， the underlying principles， methodological strengths and weaknesses， and recent research advances are summarized. Finally， future research directions are discussed to highlight opportunities for further theoretical development and practical application in the field.
