Abstract
A fan assembly includes a fan cover. The fan cover is provided with a vane assembly and is fixed by a rotating shaft, which includes blades and magnetic vanes arranged along its outer contour. The coils are evenly arranged along the fan cover. The magnetic rotor blade and the alternating magnetic field generated by the coils can drive the blades to rotate, and the rotation speed can be adjusted by changing the speed of the alternating magnetic field. The coils are fixedly installed in the outer cover of the fan, and the vane assembly is only installed by the rotating shaft, which can easily disassemble from the vane assembly. The structure is simple and has higher reliability. So, it is not easily damaged, and has a longer service life. The fan assembly can be completely waterproof, so that the product can be used in high humidity and even water.
