This paper describes the influence of rotor eccentricity on permanent magnet synchronous motor characteristics by using the finite element method and several experiments. The rotor eccentricity unbalances the magnetic force and thus increases the mechanical loss. Furthermore, a circulating current generated result in an increase of electric power loss in the permanent magnet synchronous motor with three-phase parallel winding of the stator coils. Therefore, we presented that the flux barrier rotor is effective to reduce the harmful effect of the rotor eccentricity.
