Abstract
A shaftless fan includes a fan stator, a vane rotor and a rolling bearing. The rolling bearing is installed between the fan stator and the vane rotor and includes an inner ring, an outer ring, and a plurality of rolling elements rollably installed between the inner and outer rings, and the inner and outer rings of the rolling bearing are rotated in opposite direction with respect to each other, so that the vane rotor can be rotated on the fan stator to connect the fan stator with the vane rotor through the rolling bearing, so as to achieve the shaftless effect.

A shaftless fan structure, comprising:
- a fan stator;
- a vane rotor;
- and
- a rolling bearing having a central hollow portion and installed between the fan stator and the vane rotor, and including an inner ring, an outer ring, and a plurality of rolling elements rollably installed between the inner and outer rings;
- wherein the inner and outer rings are rotated in opposite directions with respect to each other, so that the vane rotor can be rotated on the fan stator,
- wherein the fan stator is disposed inside the central hollow portion of the rolling bearing;
- wherein the vane rotor includes an impeller, a plurality of blades disposed outside the impeller, and a magnetic element installed in the impeller, and the impeller has a circular wall, and each blade is arranged around the periphery of the impeller and mounted onto the circular wall;
- wherein the impeller includes a ring portion therein, the ring portion is located between the circular wall and the fan stator, the rolling bearing is located between the ring portion and the circular wall, and the magnetic element is mounted onto an internal wall of the ring portion.
