1. A wheel hub motor comprising:
a central shaft extending along an axis;
a stator unit surrounding and connected fixedly to said central shaft, and including a positioning seat that is connected fixedly to said central shaft, and a coreless stator set that is configured as a disk and that is connected to said positioning seat; and
a rotating unit surrounding said central shaft rotatable about said central shaft, and including a rotating seat set that is sleeved on said central shaft, a bearing set, and two rotor sets that are fixedly mounted to said rotating seat set and spaced apart from each other along the axis, said rotating seat set defining a bearing mounting space that is adjacent to and surrounds said central shaft and that receives said bearing set therein, and a rotor space that is disposed away from said central shaft, that is radially spaced apart from said bearing mounting space, and that receives said rotor sets therein, said coreless stator set being disposed between said rotor sets such that, when said coreless stator set is energized, said rotor sets rotate about said central shaft so as to drive said rotating seat set and said bearing set to rotate about said central shaft.
