5:40 pm - 5:50 pm Closing remarks by the conference chairman, Dr. Dirk Neumeister


This workshop’s primary goal is to provide an in-depth look on noise and vibration behavior
of electric motors since an electric powertrain features additional and different components
as well as new operation modes compared to a conventional powertrain.
The workshop is aimed to provide some concrete examples on e-motor integration.
In this workshop you will be able to:
• Provide design guideline of how to optimize emotor for NVH
• Vehicle integration techniques for motor/invertor whine sound reduction
• Demonstrate NVH analysis method to achieve best in class motor
