[0017] Preferred embodiment of the present invention:
[0018] An axial magnetic field hub motor assembly includes a central shaft 1, a motor housing 2, a motor end cover 3, a stator assembly, a rotor assembly, and a planetary gear reducer. A first stator assembly 4 and a second stator assembly 5 are sheathed on the central shaft, and a planetary gear assembly and a rotor assembly are also arranged between the two stator assemblies. The stator assembly, the rotor assembly and the planetary gear reducer are all integrated in the motor housing 2 , the central shaft 1 runs through the whole structure, and the motor housing 2 cooperates with the motor end cover 3 .
[0019] The first stator assembly 4 includes a wound stator core, which is fixed on the stator back plate 6 . The stator backplane 6 is fixed on the motor housing 2 , and the stator backplane 6 and the motor housing 2 are positioned through a spigot.
[0020] The planetary gear reducer includes a planetary carrier 7,...
