When theheat dissipating fan 1 is powered on, thecoils 124 switch magnetic pole alternately such that a magnetic force is induced between thecoils 124 and themagnetic member 142, so as to drive thefan wheel 140 to rotate. Consequently, air can be guided by thefan wheel 140 to flow. - In general, the
magnetic member 142 is attached on the inner wall of thefan wheel 140 by an adhesive (e.g. anaerobic adhesive) . However, the quality of the anaerobic adhesive may degrade easily after being used for a long time or under high temperature such that themagnetic member 142 may come off thefan wheel 140. Furthermore, when therotor 14 is rotating, therotor 14 may come off thestator 12 due to vibration induced by high speed rotation. Accordingly, the heat dissipating fan may have a breakdown or other components within an electronic device maybe damaged. Moreover, referring toFIG. 2 ,FIG. 2 is a cross-sectional view illustrating anotherheat dissipating fan 1′ of the prior art. As shown inFIG. 2 , theheat dissipating fan 1′ utilizes amylar film 16 to be a fastener for fastening theaxle 144. However, themylar film 16 may fall off easily after being used for a long time such that therotor 14 may come off thestator 12 due to vibration induced by high speed rotation. - The invention provides a heat dissipating fan capable of holding a magnetic member stably and preventing a rotor from coming off a stator effectively, so as to solve the aforesaid problems.

The stator comprises a bearing and a winding structure, wherein the bearing is disposed in the winding structure. The rotor comprises a fan wheel, a ring-shaped casing and a magnetic member, wherein the ring-shaped casing is disposed in the fan wheel and the magnetic member is disposed in the ring-shaped casing. The fan wheel has an axle inserted into the bearing such that the winding structure is located within the magnetic member. At least one protruding portion protrudes from one side of the ring-shaped casing inwardly and is extended below the winding structure so as to hold the magnetic member and interfere with the winding structure.
- As mentioned in the above, the invention disposes the magnetic member in the ring-shaped casing and utilizes the at least one protruding portion, which protrudes from one side of the ring-shaped casing inwardly, to hold the magnetic member. Furthermore, when the axle of the rotor is inserted into the bearing of the stator, the protruding portion, which protrudes from one side of the ring-shaped casing inwardly, is extended below the winding structure so as to interfere with the winding structure. Accordingly, the protruding portion can prevent the rotor from coming off the stator when the rotor is at rest or rotating.

FIGS. 3 to 6 , theheat dissipating fan 3 comprises afan frame 30, astator 32 and arotor 34, wherein thestator 32 and therotor 34 are disposed in thefan frame 30. Thestator 32 comprises abearing 320 and awinding structure 322, wherein thebearing 320 is disposed in thewinding structure 322. In this embodiment, thewinding structure 322 has a plurality ofteeth 324 and there is agap 326 between twoadjacent teeth 324. It should be noted that the number of theteeth 324 can be determined according to practical applications and is not limited to the embodiment shown in the figures. In practical applications, a plurality of coils (not shown) is wound around theteeth 324. Furthermore, theheat dissipating fan 3 further comprises acircuit board 36 and aHall sensor 38, wherein theHall sensor 38 is disposed on thecircuit board 36. The principle of theHall sensor 38 is well known by one skilled in the art and will not be depicted herein. - The
rotor 34 comprises afan wheel 340, a ring-shaped casing 342 and amagnetic member 344, wherein the ring-shaped casing 342 is disposed in thefan wheel 340 and themagnetic member 344 is disposed in the ring-shaped casing 342. As shown inFIGS. 5 and 6 , at least oneprotruding portion 346 protrudes from one side of the ring-shaped casing 342 inwardly. In this embodiment, fourprotruding portions 346 protrude from one side of the ring-shaped casing 342 inwardly and are corresponding to fourgaps 326 between fourteeth 324. It should be noted that the number of the protrudingportions 346 can be determined according to practical applications and is not limited to the embodiment shown in the figures. To assemble therotor 34, an operator has to attach themagnetic member 344 on an inner wall of the ring-shaped casing 342. At this time, theprotruding portions 346 can hold themagnetic member 344. Afterward, the operator disposes the ring-shaped casing 342 with themagnetic member 344 into thefan wheel 340. Accordingly, when the rotor is rotating, theprotruding portions 346 of the ring-shaped casing 342 can hold themagnetic member 344 stably even without any adhesive (e.g. anaerobic adhesive) or under high temperature so as to prevent themagnetic member 344 from coming off the ring-shaped casing 342. - Furthermore, the
fan wheel 340 has anaxle 348. In this embodiment, a width W of theprotruding portion 346 is smaller than thegap 326 between twoadjacent teeth 324. Accordingly, the operator can align theprotruding portions 346 of therotor 34 with thegaps 326 between theteeth 324 correspondingly, make the protruding portions pass through thegaps 326, and insert theaxle 348 into thebearing 320 of thestator 32 such that thewinding structure 322 is located within themagnetic member 344, as shown inFIG. 5 . In this embodiment, a length L of theprotruding portion 346 covers agap 328 between themagnetic member 344 and theteeth 324 such that the protruding portions are extended below theteeth 324 of thewinding structure 322 after therotor 34 and thestator 32 are assembled. - When the
heat dissipating fan 3 is powered on, the coils (not shown), which are wound around theteeth 324, switch magnetic pole alternately such that a magnetic force is induced between the coils and themagnetic member 344, so as to drive thefan wheel 340 to rotate. Consequently, air can be guided by thefan wheel 340 to flow. Theprotruding portions 346 interfere with theteeth 324 of thewinding structure 322 in an axial direction of theaxle 348, so as to prevent therotor 34 from coming off thestator 32 when therotor 34 is at rest or rotating. It should be noted that theprotruding portions 346 may be extended below other portions of thewinding structure 322 except theteeth 324, so as to interfere with other portions of thewinding structure 322 when therotor 34 is at rest or rotating. - In this embodiment, the ring-
shaped casing 342 may be made of, but not limited to, a magnetic induction material, wherein the magnetic induction material may be, but not limited to, electro-galvanized steel (SECC). Accordingly, a magnetic attraction force can be induced between themagnetic member 344 and the ring-shaped casing 342 such that themagnetic member 344 can be attached on the inner wall of the ring-shaped casing 342 by the magnetic attraction force without the aforesaid adhesive. - As mentioned in the above, the invention disposes the magnetic member in the ring-shaped casing and utilizes the at least one protruding portion, which protrudes from one side of the ring-shaped casing inwardly, to hold the magnetic member. Furthermore, when the axle of the rotor is inserted into the bearing of the stator, the protruding portion, which protrudes from one side of the ring-shaped casing inwardly, is extended below the winding structure so as to interfere with the winding structure. Accordingly, the protruding portion can prevent the rotor from coming off the stator when the rotor is at rest or rotating.
