Abstract
The utility model discloses a bar-shaped stator core, comprising a plurality of stator units. Each stator unit comprises a bottom edge, a top edge and a coiling part. One end of the coiling part is fixedly connected with the bottom edge, and the other end of the coiling part is fixedly connected with the top edge. The bottom edge of one stator unit is hinged to the bottom edge of an adjacent stator unit. Stator units positioned at two ends of the bar-shaped stator core are in adaptive connection. Circular holes are arranged at joints of the stator units. According to the bar-shaped stator core, the plurality of stator units are connected by hinging the bottom edges; before coiling is completed, the stator core is bar-shaped to facilitate coiling; and after coiling is completed, the heat and the tail of the stator core are abutted, and thus the current operational shape of the stator core is circular. As the bottom edges are thin and are hinged, the stator core is easy to be shaped like a circle, the production efficiency is high, the fracture probability is low and the qualified rate of products is high.
Description
Technical field
The utility model relates to the brshless DC motor field, relates in particular to a kind of stator core that is applicable to universal brshless DC motor.
Background technology
It is circular that existing brshless DC motor, the shape of its stator core are mostly, but circular stator core coiling difficulty is large, and the coiling time is long, and production efficiency is low.Therefore, the bar shaped stator core occurred now, the bar shaped of bar shaped stator refers to before coiling is completed, and stator is strip, after coiling is completed, can, by the first right, make strip become round shape.So namely guaranteed the normal operation of stator core, also convenient coiling, reduce the coiling difficulty, reduces the coiling time, improved production efficiency.But also there is shortcomings in existing bar shaped stator core, such as being difficult to full circle after completing in coiling, and easy fracture in the full circle process, its production efficiency is lower; Magnetic circuit is not optimized, and the stator yoke magnetic flux is easily saturated.
The utility model content
For the weak point that exists in above-mentioned technology, it is a kind of simple in structure that the utility model provides, and difficulty of processing is little, and production efficiency is high, easily the bar shaped stator core of full circle.
For achieving the above object, the utility model provides a kind of bar shaped stator core, comprises a plurality of stator units, and each stator unit comprises base, top margin and winding section, and described winding section one end is fixedly connected with base, and the other end is fixedly connected with top margin; The base of the base of a stator unit and adjacent stators unit is hinged, is positioned at the adaptive connection of stator unit at bar shaped stator core two ends, and the junction of stator unit is provided with circular hole.
Wherein, the base of described stator unit and top margin are circular-arc, and all bases of stator unit surround circle, and all top margins surround circle.
Wherein, the edge of the base circular arc of described stator unit also is provided with boss.
Wherein, the base of described stator unit, top margin and the winding section manufacturing that is formed in one.
Wherein, all stator units of composition bar shaped stator core are by one-body molded manufacturing.
The beneficial effects of the utility model are: compared with prior art, the bar shaped stator core that the utility model provides, a plurality of stator units link together with the hinged form in base, and before coiling was completed, stator core was strip, convenient coiling; After coiling is completed, the head and the tail of stator core are docked, this moment, stator core was the figure shape of operating state.Because base is thinner, be again by being articulated and connected, be easy to full circle, production efficiency is high; The probability that fracture occurs is little, and the qualification rate of product is high.

Embodiment
, in order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
See also Fig. 1-3, bar shaped stator core of the present utility model, comprise a plurality of stator units 1, and each stator unit 1 comprises base 11, top margin 12 and winding section 13, and winding section 13 1 ends are fixedly connected with base 11, and the other end is fixedly connected with top margin 12; The base 11 of a stator unit 1 is hinged with the base 11 of adjacent stators unit 1, is positioned at the adaptive connection of stator unit 1 at bar shaped stator core two ends, and the junction of stator unit 1 is provided with circular hole 14.
The bar shaped stator core that the utility model provides, a plurality of stator units 1 link together with the hinged form in base 11, and before coiling was completed, stator core was strip, convenient coiling; After coiling is completed, the head and the tail of stator core are docked, this moment, stator core was the round of operating state.Because base 11 is thinner, be again by being articulated and connected, the junction of stator unit 1 is provided with circular hole 14, is easy to full circle, and production efficiency is high; The probability that fracture occurs is little, and the qualification rate of product is high.
The bar shaped stator core that the utility model provides, the base 11 of stator unit 1 and top margin 12 are circular-arc, and when stator unit 1 docking at bar shaped stator core two ends was got up, all bases 11 of stator unit 1 surrounded circle, all top margins 12 surround circle.Certainly this is only a specific embodiment of the present utility model, and the shape of stator unit 1 is not limited in this, and when stator unit 1 docking at bar shaped stator core two ends was got up, stator core also can be polygon.
The bar shaped stator core that the utility model provides, the edge of base 11 circular arcs of stator unit 1 also is provided with boss 15.Boss 15 can overcome the difficult full circle of traditional bar shaped stator core, the easily shortcoming of fracture, and boss 15 the area that has increased stator yoke is set, the magnetic flux by stator yoke will be larger, magnetic circuit is optimized.
The manufacturing that is formed in one of the bar shaped stator core that the utility model provides, the base 11 of stator unit 1, top margin 12 and winding section 13.The base 11 of stator unit 1, top margin 12 and winding section 13 link together by integrated mode, not only be connected firmly, and difficulty of processing are low, and production efficiency is high.Certainly this is only a preferred embodiment of the present utility model, and the connected mode of the base 11 of stator unit 1, top margin 12 and winding section 13 is not limited in this, also can be fixedly connected with by other means.
