Taking the 5kW permanent magnet synchronous motor in shaftless rim thruster as study object, the Maxwell simulation software was used to set up different degrees and types of eccentric faults to study the variation of parameters such as motor air gap flux density, electr-omagnetic torque and winding current. Fourier analysis of current was carried out,and , and the corresponding fault features were extracted by comparing with static eccentricity and dynamic eccentricity faults,which can provide a reference for the fault diagnosis of hybrid eccentricity rotor of the shaftless rim propulsion motor.
