This paper describes the influence of rotor eccentricity on the vibration characteristics of a concentrated winding interior permanent magnet synchronous motor (IPMSM) by using a finite element method (FEM) and several measurements. The rotor eccentricity primarily caused an increase in radial electromagnetic force. In addition, an IPMSM with rotor eccentricity has higher vibration acceleration than an IPMSM without rotor eccentricity.
