Abstract A prediction model for electromagnetic vibration calculation of permanent magnet synchronous motor (PMSM) accounting for effects of electromagnetic force spatial distribution and stator equivalence is established in this paper.Firstly,Maxwell stress tensor method is used to analyze the spatial and frequency characteristics of electromagnetic force.The effects of current harmonics on the frequency of electromagnetic force are also taken into account.By using finite element method (FEM),the force acting on the surface of stator teeth is calculated firstly.Then the stator structural model accounting for material anisotropic of stator core and winding is built and modal test is conducted to validate this model.Finally,the mode superposition method is used to calculate the electromagnetic vibration when electromagnetic force is transferred from electromagnetic model to structural model.The calculated results agree well with those by test.Besides,the characteristics of distributed force and equivalent concentrated force are compared.It is shown in the research of this paper that the effects of electromagnetic force spatial distribution and stator equivalence are key factors for vibration calculation.The current harmonics close to the switching frequency significantly influence the vibration according to the simulation and test results.

Key words： Permanent magnet synchronous motor electromagnetic vibration spatial distribution of electromagnetic force stator equivalence current harmonics
