    摘要: A cooling fan includes a fan housing (10) having a central tube (11) extending upwardly therefrom, a bearing (20) received in the central tube, a stator (40) mounted around the central tube, a rotor (30) having a shaft (37) extending into the bearing, and a magnetic ring (38) being fixedly mounted to the rotor to rotate with the rotor during operation of the cooling fan. The bearing is made of iron-copper alloy. The magnetic ring is made of hard magnetic material and exerts a magnetic attraction on the bearing, whereby the rotor is pulled downwardly by a magnetic attraction of the bearing on the magnetic ring to lessen the floating problem of the rotor during operation of the cooling fan.

    摘要: A cooling fan includes a fan housing (30) having a central tube (34) extending upwardly therefrom, a bearing (60) being received in the central tube, a stator (20) being mounted around the central tube, and a rotor (10) having a shaft (18) extending through the bearing. At least one notch (180, 184) is defined in an end of the shaft. A balance structure (62) is mounted around the shaft, and has a portion facing and surrounding an upper portion of the at least one notch of the shaft. The balance structure is made of magnetic material, which can attract the shaft downward to thereby counter the upward force generated by the rotor when it is driven to rotate. Accordingly, the noise problem incurred by the floating of the rotating rotor can be resolved by the present invention.

    摘要: A heat dissipating fan includes a housing (201), a stator (21), a rotor (27) and a buffer structure. The housing defines an accommodating space (202) and includes a hollow tube (201b). The tube encloses first and second bearings (22, 23) therein. The stator is arranged in the accommodating space and around the tube. The rotor has a shaft rotatably disposed in the first and the second bearings. The buffer structure includes at least a pair of magnets (25, 26) received in the tube and located between the first and second bearings. Repellent force is generated between the magnets, thereby preventing at least one of the first and the second bearing from being damaged by an accidental force acting thereon.
