Abstract: This thesis aims to reveal the main vibration consequences induced by the electromagnetic and mechanical interaction in the PMSM. In this thesis, two classes of modeling approaches, i.e. analytical model based approaches and numerical model approaches are applied for the modeling of the different types of faulty PMSMs. For the analytical model based approaches, a lumped mass method and a gradient field method are used for mechanical vibration modeling and electrical Unbalanced Magnetic Pull (UMP) modeling respectively. For the numerical model approaches, the three-dimensional finite element method are adopted in the study of magnetic field distributions and evaluation of the UMPs and UMP-induced vibration under different types of faulty motors. To obtain experimental results, five types with four grades of fault motors were designed and fabricated. Simulation and experimental results verify the effectiveness of the derived parametric models for achieving high accuracy and their respective advantages.
