A fan structure
By staggering the first and second magnetic poles in the fan structure and connecting the windings in series, the range of magnetic field effect is increased, solving the problem of dead angle during fan startup and improving the fan's startup performance and stability.

Abstract
This invention discloses a fan structure, including a base plate, a fan frame and a shaft tube, a stator assembly fitted around the outer periphery of the shaft tube, the stator assembly including a first stator core group and a second stator core group, and forming multiple corresponding first magnetic pole portions and second magnetic pole portions, which are staggered along the axial direction of the shaft tube; windings, wound around the first magnetic pole portions and second magnetic pole portions to form first windings and second windings, with insulating components between the first windings and second windings and the magnetic pole portions; a rotor, rotatably connected to the shaft tube, the rotor having magnetic elements, and a magnetic gap forming between the magnetic elements and the stator assembly; wherein any one of the first windings and any one of the second windings are connected in series to increase the range of the magnetic field, thereby increasing the area of repulsive magnetic force and the area of attractive magnetic force between the stator assembly and the rotor.
