The invention belongs to the technical field of propellers, and particularly relates to a double-layer propeller thruster driven by an axial magnetic flux motor, the double-layer propeller thruster comprises an outer shell, the axial magnetic flux motor and two propellers, the outer shell is installed on the outer side of the axial magnetic flux motor, and the propellers are installed on the two sides of the axial direction of the axial magnetic flux motor. Wherein the axial magnetic flux motor comprises a stator assembly and two rotor assemblies, the rotor assemblies are installed in the propeller, the rotor assemblies are installed on the two sides of the stator assembly in the axial direction of the stator assembly, the rotating directions of the two rotor assemblies are opposite, and the propeller is provided with positive and negative blades; the propeller further comprises a shafting assembly, and the stator assembly and the rotor assembly are detachably connected through the shafting assembly. Partial structures of the rotor assembly and the stator assembly are made of the polymer water-lubricated bearing material, and the polymer water-lubricated bearing material has good lubrication wear resistance and good corrosion resistance, so that the structure of the propeller is simplified, and the cost is saved.
