Some embodiments of the invention, one end of the adjacent rotor 1 of at least one stator tooth 22 is (for example, in Fig. 1
It is inner) at least one tooth boot portion 222 is provided with, tooth boot portion 222 is axially extending along rotor 1.Here, it is necessary to explanation, this Shen
Please in described " interior " refer to the neighbouring center position of motor 100, correspondingly, described " outward " is referred to away from electricity in the application
The direction at the center of machine 100.
That is, one of stator tooth 22 that can be in multiple stator tooths 22 above-mentioned one end set one or
Two tooth boot portions 222, it is also possible to which above-mentioned one end of the partial stator tooth 22 in multiple stator tooths 22 sets one or two
Tooth boot portion 222, can also be respectively provided with one or two tooth boot portions 222 in above-mentioned one end of each stator tooth 22.Specifically, when
When above-mentioned one end of stator tooth 22 is provided with a tooth boot portion 222, tooth boot portion 222 can be towards the front side of stator tooth 22 or rear side
Extend, when above-mentioned one end of stator tooth 22 is provided with two tooth boot portions 222, two tooth boot portions 222 can be respectively facing stator tooth
22 front side and rear side extend.Thus, it is possible to effectively improve the utilization rate of the axial magnetic field of rotor 1, improve stator and turn
Magnetic conduction effect between son 1, so as to improve the performance of motor 100.
For example, in the example of fig. 1, above-mentioned one end of each stator tooth 22 is respectively provided with two tooth boot portions 222, two tooth boots
Portion 222 is respectively facing the front side of stator tooth 22 and rear side extends.Thus, the utilization rate of the axial magnetic field of rotor 1 is effectively improved.
And for example, reference picture 7, above-mentioned one end of stator tooth 22 is provided with the tooth boot portion 222 that a front side towards stator tooth 22 extends.By
This, can equally improve the utilization rate of the axial magnetic field of rotor 1.
Some embodiments of the invention, one end away from stator tooth 22 of at least one tooth boot portion 222 is provided with boss
221, boss 221 extends towards the direction of rotor 1.Specifically, when above-mentioned one end of stator tooth 22 is provided with a tooth boot portion 222
And tooth boot portion 222 towards the front side of stator tooth 22 extend when, the front end (i.e. the free end of tooth boot portion 222) of tooth boot portion 222 can be with
It is provided with boss 221.When above-mentioned one end of stator tooth 22 be provided with a tooth boot portion 222 and tooth boot portion 222 towards stator tooth 22 after
When side extends, the rear end of tooth boot portion 222 can be provided with boss 221.When above-mentioned one end of stator tooth 22 is provided with two tooth boot portions
222, when two tooth boot portions 222 are respectively facing front side and the rear side extension of stator tooth 22, can be before the tooth boot portion 222 of front side
End sets boss 221, it is also possible to set boss 221 in the rear end of the tooth boot portion 222 of rear side, can also simultaneously in the tooth boots of front side
The rear end of the front end in portion 222 and the tooth boot portion 222 of rear side sets boss 221.
Specifically, reference picture 8 and Fig. 9, one end of boss 221 are connected with tooth boot portion 222, the other end direction of boss 221
The direction of rotor 1 extends, that is to say, that boss 221 can radially extending along stator yoke 21.Thus, it is possible to not increase
On the basis of teeth portion punching quantity, by setting boss 221 in tooth boot portion 222 so that the distance between stator and rotor 1 are more
Adjunction is near, reduces magnetic resistance, improves the magnetic conduction effect between stator and rotor 1, and poly- magnetic effect is more preferable so that magnetic field is easier
It is directed into the stator of motor 100, improves the performance of motor 100.
Alternatively, when a boss 221 is equipped with each stator tooth 22, boss 221 is located at the thickness of stator tooth 22
The same side in direction (for example, the fore-and-aft direction in Fig. 1).For example, boss 221 can simultaneously be located at the tooth boots of the front side of stator tooth 22
The front end in portion 222, or the rear end of the tooth boot portion 222 of the rear side of stator tooth 22 is located at simultaneously.Thus, it is possible to improve motor 100
Balance quality, so as to further increasing the overall performance of motor 100.
Specifically, a side surface of the adjacent rotor 1 of boss 221 is formed as plane, tapered plane or is directed away from rotor 1
The cambered surface of the direction protrusion of the heart.For example, in the example of fig. 8, a side surface of the adjacent rotor 1 of boss 221 is formed as plane,
And for example, in the example of figure 9, the adjacent rotor 1 of boss 221 a side surface formed be directed away from the center of rotor 1 direction it is convex
The cambered surface (such as arc surface) for going out.Simple structure, it is easy to process.
Alternatively, boss 221 is integrally formed with stator tooth 22.For example, boss 221 can be with punch forming, but not limited to this.
Process is simple, production efficiency is high, and processing cost is low.It is space, magnetic conductivity between traditional rotor 1 of motor 100 and stator tooth 22
It is 1, and the boss 221 in the present embodiment is the extended structure of stator tooth 22, for example, boss 221 can be the one of silicon steel construction
Part, magnetic conductivity is significantly increased, and improves the magnetic conduction effect between stator and rotor 1, and poly- magnetic effect is more preferable so that magnetic field more holds
Easily it is directed into the stator of motor 100, improves the performance of motor 100.
Specifically, the structure and size of each teeth portion punching are just the same.Thus, it is possible to improve the production effect of teeth portion punching
The utilization rate of rate and material.
Some embodiments of the invention, insulating support 4 is provided between coil 3 and adjacent stator tooth 22.For example, ginseng
According to Fig. 1, Fig. 3, Fig. 4 and Fig. 5, insulating support 4 can be formed as platy structure.Insulating support 4 can be set on stator tooth 22.
Thus, it is possible to the insulating properties between coil 3 and adjacent stator tooth 22 is improved, so as to further increasing copper factor.

In the first interface 213 can be interface that lug boss 2122 and draw-in groove 211 coordinate, two adjacent sub- stator yokes 212
Between the interface in addition to the first interface 213 be " the second interface 214 ".When stator tooth 22 is connected to stator yoke 21
When upper, the first interface 213 and the second interface 214 are respectively positioned in the bayonet socket 223 of corresponding stator tooth 22.Thus, may be used
To improve the overall construction intensity of stator, and due to technological reason, interface (i.e. the first interface 213 and the second interface
214) the possible gap in place, increased magnetic resistance, after bayonet socket 223 is stuck at interface, can increase at stator tooth 22 and interface
Contact, so as to reduce because of the increased magnetic resistance in gap.
In assembling process, multiple bar shaped yoke portion punchings, by frock extruding, bending, are adjusted to after punching is stacked
The structure of annular, then stretches into the above-mentioned another of bar shaped yoke portion's punching by the lug boss 2122 of above-mentioned one end of bar shaped yoke portion's punching
In the depressed part 2121 at end, finally the seam crossing of the first interface 213 and the second interface 214 is welded or is bonded together, with
The shape in fixed stator yoke portion 21.
Alternatively, depressed part 2121 is formed as U-lag or V-shaped groove, but not limited to this.For example, depressed part 2121 can be with
Be formed as rectangular slot, dovetail groove or semi-circular groove etc., simple structure is easy to process.
Alternatively, rotor 1 is permanent magnet magnetic ring structure, but not limited to this.
