    摘要: A motor comprising a stator and a rotor; the stator includes a first stator, a second stator, and a third stator; the stators each include at least one stator coil; the rotor includes a magnetic element, a first bearing, a second bearing, and a shaft; the stators generating a superimposed magnetic field together causes the magnetic element to rotate; when the magnetic element rotates in the first plane, the outer ring of the first bearing rotates; the center of the first bearing is located in a plane where the second bearing is located, and when the magnetic element rotates in the second plane, the inner ring of the second bearing rotates; the central axis of the shaft passes through the center of the first bearing; wherein the shaft is rotatably fixed to the first bearing and connected to the second bearing; the magnetic element located in where the central axis of the first bearing meets the central axis of the second bearing, the normal vector of the first plane is parallel to the axial direction of the shaft; the normal vector of the second plane is perpendicular to the axial direction of the shaft.
