End forms first connecting portion 21.Stator core further includes multiple tooth heads 40 and split collar 50, is formed on tooth head 40 and first
The compatible second connecting portion of interconnecting piece 21.Multiple inserting grooves 51 for inserting tooth head 40 are offered on split collar 50, it is multiple
Tooth head 40 is inserted into respectively on multiple inserting grooves 51, and is fitted to stator tooth by second connecting portion and first connecting portion 21
On 20.
Apply the technical scheme of the present invention, tooth head 40 is inserted on inserting groove 51, and can stator tooth 20 end separation, lead to
It crosses and changes tooth head 40 come stator core internal diameter needed for meeting motor different performance requirement, without opening a variety of stator punchings
Mold solves the problems, such as existing stator core type poor universality.In addition, separated by tooth head 40 with stator tooth 20, it can be full
Sufficient 20 coiling of stator tooth or any winding mode of stator slot 30, while it is easy to solve winding when the easy hanging wire of stator core coiling, injection molding
It is rushed out the problems such as slot is outer, slot effect is big, vibration and noise is big, low efficiency.
It should also be noted that, in the inventive solutions, meanwhile, tooth head 40 and split collar 50 and 30 shape of stator slot
At closed slot, it is suppressed that motor slot effect.In addition, not having to worry winding in installation production or injection molding due to being closed slot
It is rushed out outside slot and scraps, winding copper factor can do more, and be conducive to promote motor performance.
As shown in Figure 4 and Figure 5, in the technical scheme of this embodiment, tooth head 40 includes 41 He of tooth head stem being connected
Tooth head-tail 42, curved end is formed in tooth head stem 41, and tooth head-tail 42 forms second connecting portion.Tooth head 40 passes through its tooth
Head-tail 42 is connect with stator tooth 20, and the curved end formed in tooth head stem 41 constitutes the inner face of stator core.
Preferably, as shown in Figure 3 and Figure 5, in the technical scheme of this embodiment, first connecting portion 21 is to be provided with stator
Split groove on the end of tooth 20, second connecting portion are split boss compatible with split groove.When in use, by split
In boss inserting to split groove, the connection of tooth head 40 and stator tooth 20 is realized.Preferably, split boss rounded at the edge should meet
Less than split concave edge fillet, without interference when making to install, and it is fitted close.
More preferably, split groove is trapezoidal split groove, and the opening of split groove is less than the bottom of split groove
The shape in portion, split boss is adapted with split groove.Trapezoidal split groove is connected with trapezoidal split boss, and anticreep may be implemented
Effect reinforces the bonding strength of tooth head 40 and stator tooth 20.
As shown in fig. 6, multiple split teeth 52 are formed on split collar 50 in the technical solution of the present embodiment, it is two neighboring
An inserting groove 51 is formed between split tooth 52.When in use, the size of split collar 50 can only adjust tooth without adjustment
First 40 size can realize the adjustment to stator core internal diameter.Optionally, it is formed with and is used in the middle part of the inner wall of split tooth 52
Block the silent portion 521 of the opening of stator slot 30.Split collar 50 is mounted on to the inside of stator yoke 10, may be implemented to stator slot
30 closure.
Optionally, the inner wall two sides of split tooth 52 are formed with the fastening part 522 for contacting with tooth head 40.It is using
When, tooth head stem 41 and 42 junction of tooth head-tail are mounted on the inserting groove 51 of split collar 50, tooth head stem 41 is abutted
The fastening part 522 on side ring side in split collar makes several tooth heads 40 be fixedly attached to split collar 50 by the cooperation of fastening part 522
On, constituting interior outside is to close circle configurations.
It should be noted that by L1 the and L2 size for changing tooth head stem 41, to change split split collar 50 and tooth head
The interior circular diameter L3 and L3 ' of 40 compositions.So that interior circular diameter L3 and L3 ' is changed using which, does not affect its inside and outside circle
Concentricity preferably improves the property such as power of motor, revolving speed, temperature rise to constitute better motor overall structure with rotor assembly
Can, electric efficiency is improved, the vibration and noise of motor is effectively improved.
Fig. 7 shows the structure of stator core in the prior art, and in this configuration, the head of stator tooth 20 is larger to have slot
Shoulder and notch.And in the technical solution of this present embodiment, as shown in figure 3, the size on the head of stator tooth 20 is equal to or less than
The size of the bottom of stator tooth 20.In this way, slot shoulder and notch of the stator tooth 20 of the present embodiment without traditional core structure, effectively change
Kind coiling hanging wire situation, improves coiling copper factor, quality and efficiency.
As shown in Figures 2 and 3, in the technical scheme of this embodiment, stator yoke 10 is split type structure, including detachable
The the first semicircle stator yoke 11 and the second semicircle stator yoke 12 of connection, in order to process and manufacture.Preferably, the first semicircle stator
Yoke 11 and the second semicircle stator yoke 12 are connected by plug-in mounting structure 13.When in use, by split collar 50 come 40 He of split tooth head
Two semicircle stator yokes, it is ensured that it is bad to effectively reduce motor electromagnetic sound for the inside and outside circularity of stator core.Meanwhile two semicircles
After stator yoke is fixed by 50 split of split collar, the contact surface of tooth head Yu tooth tail is increased, makes to be more firmly mounted.
As other optional embodiments, stator yoke 10 or integral structure.
, can be under the limitation with the stator core of a series of same outer diameter using technical solution of the present invention, it can be with
It selects different stator iron core tooth capitiforms at different stator core internal diameters according to performance requirement, improves motor performance and efficiency, it is real
The versatility of existing stator core, reduces mold opening cost.In addition, stator core slot opening, winding efficiency is high, and is not in hanging wire
It is bad.On the other hand, it is closed slot after the complete split of stator iron core tooth yoke, effectively inhibits slot effect, reduces motor vibration
Dynamic and noise, improves electric efficiency.
