Abstract :
For the comfort and security of users, noise of electric motors is a critical issue. The harmonic content of the magnetic pressure inside the air gap being the source of the sound radiated by the stator, it suits to know the impact of field weakening. We will show that for some load angles the pressure harmonics change so that the field weakening could be heard.
