Abstract：In allusion to the problem of the surface-mounted permanent magnet motor with the rotor eccentricity, a static eccentric analytical model was established based on the boundary perturbation method, where the analytical expressions of eccentric no-load air-gap magnetic field flux density were deduced by the use of magnetic vector potential. The eccentric disturbance ε is dimensionless in the analytical model. Comparing the flux density and the unbalanced magnetic force of the analytical results with the finite element analysis results, the correctness and effectiveness of the eccentric model is demonstrated.
