This presentation will give an overview of the many factors influencing the e-nvh performance in a BEV car. Examples of successful noise mitigation actions will be presented, challenges related to dealing with high frequency noise components in measurements will be discussed and finally some of the methods and techniques will be covered

• Overview of electric drive unit phenomena for both PMSM and ASM machines
• Reduction of e-motor harmonics through optimized rotor design
• Optimization of the electric drive unit encapsulations
• Challenges related to inverter switching harmonics in complete vehicle
