Description
Technical field
The utility model relates to a kind of alternating current generator stator cores.
Background technique
Conventional motors design, stator punching, which is integrally punched from after fold button, becomes required stator, during stator processing,
Generation waste material is more, and stock utilization is lower, higher cost；Simultaneously as stator embeds the wire again after using first coiling, processing technology
Complexity, cost of labor is higher, and production automation degree is not high.
To solve the above-mentioned problems, application No. is 201610021670.0 Chinese patents to disclose a kind of brushless motor
Outer Wound-rotor type stator core and the folded method of punching, can be used after outer Wound-rotor type carries out coiling to teeth portion punching and use stator yoke punching again
Punching is clamped with stator teeth punching punching, and threading speed is fast, and coil winding machine is of less demanding, effectively reduces production cost,
Improve production efficiency.But still there are problems that when coiling since pulling force effect causes to collapse outside coil.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of structure design conjunction
The alternating current generator stator core that reason, coil will not collapse outside.
The technical scheme in the invention for solving the above technical problem is: a kind of alternating current generator stator core, including
The punching of yoke portion and teeth portion punching, yoke portion punching and teeth portion punching is detachable is assembled together；Teeth portion punching includes multiple teeth, this
A little teeth are arranged in a ring, are provided with notch between two neighboring tooth；It is characterized by: the top of the tooth extends shape to two sides
At polar cap.
The bottom of tooth described in the utility model is provided with pole shoe, and the pole shoe of two neighboring tooth is connected.
The junction of the pole shoe of the two neighboring tooth of the utility model is provided with slot.
It is provided with card slot in yoke portion described in the utility model punching, is provided with strip, strip in the teeth portion punching
It is clamped with card slot, so that yoke portion punching and teeth portion punching is detachable is assembled together.
Yoke portion described in the utility model punching and teeth portion punching are annular.
Yoke portion described in the utility model punching is circular ring shape or polygonal annular.
The quantity of tooth described in the utility model is 8 or 12.
Polar cap described in the utility model is located at the outside of notch.
The utility model compared with prior art, has the following advantages that and effect: the punching of yoke portion and teeth portion punching are detachable
Formula is assembled together, and is no longer an integral structure, and the punching mode of tooth yoke separation can be used when processing in this way, has material use
The advantages that rate is high, high degree of automation, at low cost；Polar cap can prevent from causing to collapse outside coil due to pulling force effect in coiling, together
When be also used as a part of forehead magnetic circuit, improve magnetic field output.

Referring to figures 1-3, the utility model embodiment includes yoke portion punching 1 and teeth portion punching 2.
Yoke portion punching 1 and teeth portion punching 2 are non-Unitary structure.Yoke portion punching 1 is annular, and card slot is provided in inner ring
11；Teeth portion punching 2 is annular, strip 21 is provided on outer ring, strip 21 and card slot 11 are clamped, so that yoke portion punching 1 and tooth
Portion's punching 2 is detachable to be assembled together.In the present embodiment, yoke portion punching 1 is circular ring shape or polygonal annular.
Teeth portion punching 2 includes multiple teeth 26, these teeth 26 are arranged in a ring.Be provided between two neighboring tooth 26 convenient for around
The notch 25 of line.In the present embodiment, the quantity of tooth 26 is 8 or 12.
The bottom of tooth 26 is provided with pole shoe 23, and the pole shoe 23 of two neighboring tooth 26 is connected, and junction is provided with slot 22,
Slot 22 plays the role of reducing noise.
The top of tooth 26 extends to form polar cap 24 to two sides, and polar cap 24 is located at the outside of notch 25.Polar cap 24 plays coil 4
It to the effect of support, can prevent from causing to collapse outside coil 4 due to pulling force effect in coiling, while also one as forehead magnetic circuit
Point, improve magnetic field output.
Yoke portion punching 1 and teeth portion punching 2 are by progressive die automatic punching shear, and from fold button, teeth portion punching 2 is packed into insulation framework 3
Afterwards, by automatic coil winding machine by 4 automatic winding of coil in insulation framework 3, then will be packed into yoke around the teeth portion punching 2 that makes again
Portion's punching 1.
In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named
Title etc. can be different, and above content is only to the utility model structure example explanation described in this specification.
All equivalence changes or simple change done according to structure, feature and principle described in the concept of the patent of the utility model, are wrapped
It includes in the protection scope of the utility model patent.Those skilled in the art of the present invention can be to described
Specific embodiment does various modifications or additions or is substituted in a similar manner, without departing from the knot of the utility model
Structure or beyond the scope defined by this claim, all should belong to the protection range of the utility model.
