Description
Technical field
The utility model relates to fan art, is specifically related to a kind of brushless electric fan.
Background technique
As everyone knows, progress along with society, the industrialization product that more and more can be convenient for people to daily life produces in a large number, arranged among 1 year four seasons, the most tangible sign of each conversion in season is exactly a variation of temperature, can keep body temperature by the mode that increases clothing the autumn and winter people, and people are conformed, and during the broiling summer people often the mode by increasing human body periphery circulation of air flow speed the heat of human body is outwards distributed as early as possible, to reach purpose to body temperature lowering.Can realize that radiating mode comparison typical devices is exactly a fan as mentioned above.
The fan product is kind of a technology maturation now, again the product of knowing very well for the Consumer.And just known to the people, fan generally all drives by motor.And traditional motor is generally based on charged brush class motor.Utilization rate of electrical is lower, cause its energy waste serious, and rotational speed regulation narrow range, volume are big, limited Applicable scope greatly, in addition, its motor shaft fixes by insertion method and fan blade, poor stability, be prone to the fan blade dropping situations, cause product quality problem, certain hidden danger is arranged to personal safety.
The model utility content
The purpose of this utility model is, at above-mentioned deficiency, provides the brushless electric fan of a kind of compactness rational in infrastructure, stable, energy-conservation, safe and reliable and rotational speed regulation wide ranges, long service life.
For achieving the above object, technological scheme provided by the utility model is:
A kind of brushless electric fan, it comprises a flabellum and a brushless electric machine, this brushless electric machine comprises stator group spare and one and the suitable rotor assembly of this stator module, this rotor assembly and described flabellum integrated injection molding.
Described stator module comprises a casing and is separately fixed at the drive circuit on this casing and is wound with the iron core of coil that this iron core is provided with an axis hole, and described drive circuit is connected with coil on the described iron core.
Described rotor assembly comprises a rotating shaft and a magnetic guiding loop, and this magnetic guiding loop places in the cavity of described flabellum, and described rotating shaft one end is fixed on the described flabellum through integrated injection molding, and the other end runs through the axis hole on the described iron core, and is provided with a snap ring.
Described drive circuit comprises that a pcb board and is arranged on the control IC on this pcb board.
Described control IC is a Hall IC.
The bottom of described casing forms an assembly department to outer lug.Be convenient to install and use.
The beneficial effects of the utility model are: the utility model design is ingenious, reasonable, adopts brushless electric machine and flabellum suitable, and the rotational speed regulation wide ranges not only increases substantially the energy-saving power of product, but also reduced volume greatly, the reduction fabricating cost; In addition, rotor assembly and flabellum are integrated injection moldings, and be simple in structure, compact, cooperates firmly, and safe and reliable, good operating stability increases the service life effectively, promotes quality of product, is beneficial to extensive popularization and strengthens enterprise competitiveness.Be provided with Hall IC, the level of integration height can reduce the quantity of components and parts effectively, improves product quality stability, reduces cost.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
