Further, the stator body is made of a pair of of the stator punching being oppositely arranged.
Further, the stator punching includes that annular endplate and several annulars are uniformly arranged on the annular endplate
End face on tooth plate, form holding tank between adjacent two tooth plates, the tooth plate of a stator punching is fixedly connected on another
In the corresponding holding tank of stator punching.
Further, the skewed slot is located between two adjacent tooth plates of the stator body.
Further, the number of the tooth plate of each stator punching is four.
Further, two adjacent skewed slots form splayed.
Further, the casing is all made of galvanized steel strap cold punching with the stator punching and is pressed into.
Further, the tooth plate of the stator punching is uniformly distributed along the axis annular of the annular endplate.
It can be seen from the above technical scheme that the utility model has the advantages that：Manufacture craft is few, reduces energy consumption, efficiency
High, improvement starting mode of pump performance.
Other than objects, features and advantages described above, the utility model also has other purposes, feature and excellent
Point.Below with reference to figure, the utility model is described in further detail.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.In the accompanying drawings：
Fig. 1 is the stereo-resolution structural schematic diagram of the utility model.
In figure label for：Stator body 1, annular endplate 111, tooth plate 112, holding tank 113, skewed slot 12, connects stator punching 11
Line piece 3, casing 4.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
With reference to a kind of brushless auto pump stator shown in FIG. 1, including skeleton and casing 4, the skeleton is arranged in institute
It states in casing 4, the skeleton includes stator body 1 and lug plate 3, and the stator body 1 is connected to by being molded with the lug plate 3
Together, processing technology is succinct, and stator winding mode is simple, and it is equally distributed oblique in a ring that the stator body 1 is equipped with several
Slot 12, stator winding are arranged on the stator body 1.Stator is fed back to and is connected with stator by Hall element induced potential
Controller on, the electric current of controller output variation, the electric current of variation passes through stator winding in different directions so that stator body
Continually changing magnetic pole is generated on 1 to complete the effect of commutation, and makes water pump steady running, the setting of the skewed slot 12
The stator body 1 is set to effectively reduce additional energy consumption.
The stator body 1 is made of a pair of of the stator punching 11 being oppositely arranged, the casing 4 and the stator punching 11
It is all made of galvanized steel strap cold punching to be pressed into, subtracts zinc-plated technical process, avoid zinc-plated influence and shortening to environment again
Production cycle of product.
The stator punching 11 includes that annular endplate 111 and several annulars are uniformly arranged on the annular endplate 111
Tooth plate 112 on end face, forms holding tank 113 between adjacent two tooth plates 112, and the tooth plate 112 of a stator punching 11 is solid
Surely it is connected in the corresponding holding tank 113 of another stator punching 11, the skewed slot 12 is located at adjacent two of the stator body 1
Between a tooth plate 112, and two adjacent skewed slots 12 form splayed.
Preferably, the number of the tooth plate 112 of each stator punching 11 is four, and the tooth plate 112 of the stator punching 11
Axis annular along the annular endplate 111 is uniformly distributed.
Exist since the stator punching 11 carries out blanking molding using plate, then with a pair of of 11 reverse injection molding of stator punching
Eight skewed slots 12 are formed together, are laminated than conventionally employed spiral tooling multi-disc, have that easy to operate, process is few, efficient etc. excellent
Point；Since stator has eight grades of skewed slots 12, it is uniform that rotor, which enters in magnetic field with the magnetic field produced, is not mutated, so subtracting
Few influence to rotor cogging torque, location torque when without starting mode of pump improve the startability of water pump.
The preferred embodiment that these are only the utility model, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
