Reduction of vibration and acoustic noise in permanent magnet synchronous motor by optimizing magnetic forces

Two methodologies are proposed in this paper to reduce electromagnetic vibration and noise of permanent magnet synchronous motor. A multiphysics model is firstly established to predict the vibration and noise. Experimental tests are conducted to validate the model. Then, the source of the vibration...
