Abstract: A cooling fan and dynamic pressure bearing structure is disclosed. The cooling fan includes a base portion, a bearing portion, a dynamic pressure bearing, a coil assembly, and an impeller assembly. The dynamic pressure bearing is received in the bearing portion. A plurality of pressure collecting grooves is arranged in an inner surface of a shaft hole of the dynamic pressure bearing at intervals for receiving lubricating oil. Each pressure collecting groove has two slanted grooves extending slantways which connect with each other at one end to form a connecting point. A transverse groove extends from the connecting point backward the direction of the two slanted grooves. Based on the special design of the pressure collecting groove, the present invention increases the area that creates pressure to increase the intensity of the pressure and decrease the number of pressure collecting grooves to reduce processing loads and production costs.

Abstract: A motor magnetic pre-stressing apparatus includes a stator and a rotor. The rotor is pivoted with the stator. The stator includes a lower insulating frame and a magnetic-guiding ring, and the magnetic-guiding ring is installed on the lower insulating frame. The rotor has a magnetic element, and the magnetic element has even radial magnetic poles. Thereby, by utilizing the attraction between magnetic-guiding ring and the magnetic element, a magnetic pre-stressing force is generated to absorb the rotor downwards so that the rotor rotates stably and smoothly.
