Benefits of technology

[0004] The present invention provides a magnetized fan and a method of fabricating the same. The fan is fabricated by injecting magnetic material into the fan at the time while the blades of the fan are formed. Thereby, the blades are intrinsically magnetic without the requirement for installing a magnetic device. As the magnetic device is not required, the volume of the fan can be reduced.

Problems solved by technology

As a result, the space for installing the fan stator is restricted, and the number of magnetic poles and windings are limited to affect the rotating speed of the fan.
The performance of the fan is thus seriously degraded.

Embodiment Construction

[0013] Referring to FIG. 1, the fan 1 includes a hub 10 and a plurality of blades 10 extending radially from a periphery of the hub 10. The hub 10 and the blades 11 can be formed integrally or at separate processing steps. The blades 11 can be axial-flow type, centrifugal-flow type, inclined-flow type or transverse-flow type blades to generate and guide a desired air flow.

[0014] In this embodiment, magnetic material is injected into bulk material for fabricating the fan 1, such that a plurality of N and S poles are formed to construct a plurality of sectors 12. In the exemplary embodiment as shown in FIG. 1, the sectors 12 are distributed along the periphery of the periphery of the hub 10. It will be appreciated that the sectors 12 can also be distributed in other positions such as the edges of the blades 11 as shown in FIG. 2. According to specific requirement, the magnetic material can be injected into either the hub 10 or the blades 11 only, or both the hub 10 and the blades 11,...

Abstract

A magnetized fan and a method of fabricating the same are disclosed. The fan has a hub and a plurality of blades radially extending from a periphery of the hub. The fan is fabricated from magnetic material. Thereby, sectors are formed multiple N and S poles. To fabricate the fan, the N and S poles are arranged in accordance with the requirement of the sectors, and the magnetic material is injected to the fan according to the arrangement of the N and S poles. The magnetic material is then magnetized to generate magnetic force.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates in general to a magnetized fan and a method of fabricating the same, and more particularly, to a fan which is fabricated by injecting magnetic material into the blades of the fan, such that sectors are constructed by multiple N and S poles. [0002] The conventional fan blades are made of plastic material, such that a magnetic device such as a magnet in the fan blades, such that fan blads can be used as the fan rotator to interact with the fan stator. [0003] As the conventional fan blades are formed separately with the magnetic device, more processing steps are required. Further, the magnetic device occupies an additional volume of space, such that the internal space of the hub is reduced when the fan blades are attached thereto. As a result, the space for installing the fan stator is restricted, and the number of magnetic poles and windings are limited to affect the rotating speed of the fan. The performance of the fan ...
