Abstract
Provided is a magnetic frame. A notch is formed in the magnetic frame to achieve rotating balance. Due to the fact that the notch is formed in the magnetic frame, after fan blades are installed on the magnetic frame, the unbalanced weight of the fan blades is offset by the notch, and a fan can achieve balanced rotating. In the fan blade rotating process, wind resistance generated by fan blade rotating can be damaged by utilizing the notch. A rotor utilizing the magnetic frame and the fan utilizing the rotor are further provided.
Description
Technical field
The present invention relates to a kind of magnet frame, rotor and fan, particularly a kind of magnet frame of heat transmission, rotor and fan thereof.
Background technique
Electronic technology develops rapidly in recent years, and high frequency, high speed and the intergrated circuit of electronic device intensive and microminiaturized increases severely unit volume electronic device heating value.For making all parts maintain good performance, must in the time of heat generation, heat be shifted out in time, therefore generally adopt fan to realize quick heat radiating for the heat radiation of electronic device.
Traditional fan is mainly made up of housing, rotor assembly, stator module etc.Because fan is to be with moving air flow to move while rotating by it, if fan center of gravity has skew, the phenomenon of when it rotates, generation being rocked or being vibrated.Above-mentioned phenomenon of rocking or vibrate not only makes fan produce noise, affects radiating effect, and can cause the rotating shaft of fan to accelerate fatigue and shorten working life of fan.
Summary of the invention
In view of this, be necessary to provide a kind of magnet frame, rotor and fan thereof that can keep balance.
A kind of magnet frame, forms breach on described magnet frame, for reaching rotary balance.
A kind of rotor, comprises magnet frame, is located at magnet in magnet frame, is located at the wheel hub of magnet frame periphery and by the peripheral outward extending some flabellums of wheel hub, described magnet frame is above-mentioned magnet frame, and described magnet frame reaches rotary balance for secondary rotor.
A kind of fan, the stator that comprises rotor and coordinate with rotor, described rotor is above-mentioned rotor.
Owing to thering is breach on this magnet frame, after magnet frame has been installed flabellum, utilize breach to offset the weight imbalance of flabellum, make fan reach balanced rotation.Have again, in flabellum rotary course, utilize this breach can destroy the windage raw due to fan blade rotating movable property.
With reference to the accompanying drawings, in conjunction with concrete preferred embodiment, the invention will be further described.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1-2, rotor of the present invention comprises magnet frame 10, sleeve 20 and rotating shaft 30.This magnet frame 10 is one-body molded by metallic material.Sheathed this rotating shaft 30 of this sleeve 20 is also arranged at the center position of this magnet frame 10.This sleeve 20 can be by manufacturing such as the metallic material such as copper, iron, and it is for being fixed on rotating shaft 30 in magnet frame 10.This rotating shaft 30 is cylindrical shaft-like, and this magnet frame 10 is and concentric circular of this rotating shaft 30.Understandably, this rotor also comprises the magnet be located on magnet frame 10 internal surfaces, be located at the wheel hub of magnet frame 10 peripheries and by the peripheral outward extending some flabellums of wheel hub, this magnet frame 10 is for protecting magnet, wheel hub, prevents magnet, wheel hub distortion or damages.In the present embodiment, this rotating shaft 30 is located on sleeve 20, and this rotating shaft 30 also can be fixed on wheel hub certainly.This rotor is used for being installed in a fan, and in addition, except rotor, fan also comprises the parts such as driver part (not shown), stator, fan frame.
This magnet frame 10 comprises peripheral first portion and the second portion at center, and wherein first portion comprises first paragraph 11, and second portion comprises second segment 12, the 3rd section 13, the 4th section 14 and the 5th section 15.As shown in Figure 2, the direction that rotating shaft 30 is extended is defined as laterally, is longitudinal perpendicular to the direction of this rotating shaft 30.The first paragraph 11 of this magnet frame 10 is from the peripheral longitudinal extension of this second portion.This first paragraph 11 comprises the inner side of close this rotating shaft 30 and the outside away from this rotating shaft 30.The second segment 12 of this second portion is from the horizontal expansion left of the inner side of this first paragraph 11.Connect this second segment 12 for the 3rd section 13 towards these rotating shaft 30 longitudinal extensions.Connect the 3rd section 13 towards the oblique left extension of this rotating shaft 30 for the 4th section 14.Connect the 4th section 14 towards these rotating shaft 30 longitudinal extensions for the 5th section 15.This first paragraph 11, second segment 12, the 3rd section 13, the 4th section 14 and the 5th section 15 are integrated.
On this first paragraph 11, offer the breach 110 of opening towards the outside of this first paragraph 11.The quantity of breach 110 can be adjusted according to the size of magnet frame 10, but is preferably two or one.In the present embodiment, on this first paragraph 11, offer two semicircle shape breach 110, and the adjacent setting of this two breach 110.Two breach 110 are not interconnected and between the two, form a protuberance.Breach 110 can be by the chemical mode such as physics mode or corrosion formation such as boring, punching press cut.Because the opening of breach 110 is towards the outside of this first paragraph 11, therefore in manufacture process, can manufacture breach 110 from the inner side, lateral of this first paragraph 11, simplify manufacturing process.
Because flabellum utilizes injection forming method manufacture conventionally, in manufacture process, may cause due to the impact of the factors such as pressure, plastic flow, die cavity temperature the situation of the Density inhomogeneity of flabellum, final flabellum rocks, produces noise because weight imbalance causes fan in rotary course.And the present invention first carries out balance test to flabellum etc., again according to the weight unbalance condition of flabellum, on magnet frame 10, appropriate location forms the breach 110 of suitable size, after magnet frame 10 is installed other fan parts such as flabellum, utilize breach 110 can offset the weight imbalance of flabellum, make fan reach balanced rotation.Have again, in rotor rotation process, utilize this breach 110 can destroy the windage raw due to fan blade rotating movable property.Because magnet frame 10 is to be made up of metallic material, its proportion is greater than other parts of being made up of plastic cement, as flabellum.Therefore, on magnet frame 10, form breach 110 and can, with less size, realize more effective counterbalance effect.Have, breach 110 is arranged at peripheral first paragraph 11 places of magnet frame 10 again, due to larger apart from rotating shaft 30 (that is to say rotating center), can pass through larger turning radius, offsets larger moment of torsion, more effectively to change the unbalanced problem of flabellum.
Distance between inner side and the outside of this first paragraph 11 is greater than the radius of this breach 110, limits 110 of this breach and is arranged on this first paragraph 11.The radius of magnet frame 10, that is to say the ultimate range in magnet frame 10 centers to the outside of first paragraph 11, is greater than 10:1 with the ratio of the radius of this breach 110.Therefore for magnet frame 10 generally speaking, the size of breach 110 is less, does not affect the overall appearance of magnet frame 10.
