Electrification in the automotive market has grown rapidly over the last decade as a result of new government regulations imposed to reduce emissions. This has resulted in an increase in the market share of electric vehicles. With the advancement of this technology, engineers have faced new challenges in the design of new vehicles, one of which is related to NVH and occupant comfort. As a result, considerable effort is being expended to reduce noise and vibration while increasing efficiency in order to achieve better ranges. The main goal of this thesis work is to investigate and comprehend the primary causes of noise and vibration generation in electric machines, as well as the impact of design choices on electric machine losses and noise generation.
