In the current societal landscape, there is a notable inclination towards the acceptance and adoption of electric vehicles, prompting heightened attention from academia and literature towards research and technological advancements in all aspects of electric vehicle design. As the most crucial component of an electric vehicle, the motor holds particular significance. Thus, this thesis centers on the analysis and examination of an electric motor for a small-scale transportation vehicle. The primary aim is to investigate the causes of noise and vibrations in electric motors, alongside conducting an analysis of Sound Pressure Level and order tracking to assess the motor's acoustic performance. Subsequently, employing the techniques outlined in this study, the objective is to propose a motor design that maintains motor performance while reducing noise and vibration production. This redesign of the base motor will entail the application of advanced motor design techniques, specifically focusing on the geometric design of internal motor components.
