Abstract :
This paper presents a study on motor vibration reduction according to the stator shape design in a permanent magnet synchronous motor (PMSM). Three PMSM models, with different stator tooth width and yoke width, as well as slot opening and tooth tip geometry, are built and analyzed based on the comparison of local force and natural frequency of PMSM with modal analysis. Also, the vibration generated from the deformation of stator is analyzed with considering harmonic component, and the effectiveness of each design parameters on vibration reduction is concluded in final.
