Acoustic Signature Analysis and Sound Source Localization for a Three-Phase AC Induction Motor

As part of the recent electrification of the transportation industry, internal combustion engines are being coupled with or replaced by electric motors. This movement towards an electrified drivetrain poses new noise, vibration, and harshness (NVH) challenges related to electric motors. In this pape...
