Numerical Investigation of Axial Flux Motors For Urban Air Vehicles

Kurzfassung

The primary objective of this thesis is to perform a detailed numerical analysis of the vibroacoustic behavior of an axial-flux-motor designed for urban air vehicles and to develop a structured workflow. The research aims to establish a process chain that includes simulating the electromagnetic properties, conducting structural-mechanical analyses, and evaluating the resulting Sound radiation patterns of the electric motor. ANSYS simulation tools, such as ANSYS Maxwell and ANSYS Mechanical, have been utilized throughout this analysis.The significance of this study lies in the intricate interaction between the electromagnetic properties, structural mechanics, and sound radiation of the axial flux motor, particularly in the application of urban air vehicles. By examining these interrelated aspects, the research provides valuable insights into the motor’s operational performance and environmental impact, emphasizing the importance of noise and vibration control in improving both motor performance and public perception. The objective is to develop a specialized workflow for computational noise analysis of AFMs, utilizing state-of-the-art harmonic workflow. This workflow aims to address the unique challenges faced by AFMs, such as effciency demands, noise compliance, and overall reliability under flight conditions. By overcoming these challenges, the goal is to contribute to advancements in Electric motor technology, enhancing the sustainability and performance of urban air vehicles.
