Abstract: A fan structure includes a base, a circuit board, a coil assembly, a fan blade and a bearing assembly. The circuit board is arranged on the base and includes an electronic component disposed thereon. The coil assembly is arranged on the base and electrically connected to the circuit board; the electronic component is arranged at an area outside of another area directly underneath the coil assembly. The internal of the fan blade includes a magnet; a bearing assembly is provided for the fan blade pivotally attached to the base therewith; the magnet is disposed at an external of the coil assembly. Therefore, the electronic component would not occupy the space in the axial direction of the motor in order to reduce the height of the fan blade without affecting air intake; the electronic component is visible from the outer appearance such that the repair of the circuit is facilitated.
