Electromagnetic vibration analysis of Permanent Magnet Synchronous Motor (PMSM) under eccentricity fault

Abstract

The electric vehicle (EV) market has witnessed a remarkable surge in recent years due to various benefits addressing consumer needs, industry demands, and environmental concerns. This paradigm shift towards electric mobility represents a pivotal moment in transportation history, revolutionizing vehicle conception, usage, and sustainable power sources. The migration towards electric vehicles is driven by several factors including environmental sustainability, technological advancements, economic viability, and cost savings, offering compelling solutions through innovations in battery technology and electric motors that extend driving ranges, accelerate charging times, and improve overall vehicle performance and affordability. Advancements in electric motor technologies are critical for enhancing EV performance, efficiency, reliability, and sustainability. Innovations such as optimization of installation space, enhanced power density, active noise and vibration control systems, and efficient thermal management solutions pave the way for continued growth and adoption of electric mobility. However, managing vibration in electric motor systems remains a significant challenge, particularly during high-speed operation, necessitating optimization of motor designs to minimize vibration while maintaining performance. This thesis aims to integrate structural simulation capabilities into the EMWorks 2D and 3D electromagnetic simulators, enabling analysis of dynamic and vibration behavior of electric machines under diverse fault conditions, notably rotor eccentricity. The thesis is structured into an introduction, three chapters, and a conclusion, with each chapter dedicated to exploring the proposed integration method for simulation features and examining the vibrational behavior of PMSM designs under fault conditions using numerical simulation.
