• The articles studies the effect of stator magnetic wedges on the electromagnetically-induced acoustic noise and vibration of a squirrel cage induction machine. Firstly, a review of previous studies analysing the effects of magnetic wedges both on electromagnetics and vibro-acoustic domain is done. Then, simulations are performed with MANATEE® software to quantify the reduction of noise and vibrations due to Maxwell forces with the use of magnetic wedges in a squirrel cage induction machine presenting a strong resonance due to slotting effect. A sensitivity study is carried on the magnetic permeability of the wedge and it is shown that the maximum sound pressure level and vibration reduction only reaches 2 dB with a relative magnetic wedge permeability of 20.
