ABSTRACT:
A heat-dissipating fan of the invention has an axle, a bearing, a rotor and a stator. The axle and the bearing are made of a ceramic material, and are located at a central location of the rotor and the stator. The bearing is a hollow cylinder integrally formed into a single body, and has a central hole and a recess at its bottom. The axle penetrates through the central hole of the bearing to contact the recess. A magnetic force center of the silicon steel sheet is at a level lower than that of the magnetic bar to generate radial and axial force components, allowing stable rotation of the rotor. The heat-dissipating fan of the invention provides advantages such as low friction, lower noise, low energy consumption, high performance and high stability.
