Abstract

This paper presents a comprehensive analysis on the rotor unbalanced magnetic pull (UMP) and the consequent mechanical response in 6 typical running conditions in a 20000 rpm high speed permanent magnet synchronous motor (HSPMSM) through finite element analysis (FEA) and experiment. The 6 running cases include normal full-load, normal half-load, normal no-load, static air-gap eccentricity (SAGE) full-load, SAGE half-load, and SAGE no-load. The mechanical responses include the force-caused deformation, the radial vibration, and the dynamic harmonic response due to UMP. It shows that the increment of the load will increase the rotor deformation as well as vibration, and the SAGE case will induce a larger deformation to the rotor and cause a more intensive vibration than the normal condition when with the same load. The harmonic response of the rotor will obtain a max deformation amplitude at 3180Hz and 6080Hz.
