摘要：
This paper describes the influence of rotor eccentricity on permanent magnet synchronous motor characteristics. Specifically, we studied the influence of rotor eccentricity on permanent magnet synchronous motor characteristics by conducting a magnetic field analysis and several experiments. The rotor eccentricity unbalances the magnetic force and thus increases the mechanical loss. Furthermore, a circulating current generated in two three-phase windings connected in parallel results in an increase in electric power loss in the permanent magnet synchronous motor.
