This tutorial on magnetic noise control techniques of electric machines was presented at the International Conference on Electrical Machines in Valencia, 5th September 2022 by J. Le Besnerais. The tutorial
The noise emitted by Electric Drive Units (EDU) of Hybrid Electric Vehicles or full Electric Vehicles (HEV/EV) is a key contributor to the overall perceived quality of the vehicle. This
Acoustic noise sources in Hybrid Electric Vehicles or full Electric Vehicles (HEV/EV) must be controlled to guarantee an adequate level of acoustic comfort to both passers-by, drivers, and passengers. This
Electromagnetic forces can be a major source of unpleasant noise in electric machines. The presentation focuses on understanding how magnetic noise and vibration are generated by slotting harmonics and switching
