Ground is connected to the additional teeth portion 3 of axial one end of the teeth portion 2, and two yoke portions 1 axially align engagement, wherein, Mei Gesuo
The additional teeth portion 3 for stating stator department is inserted between two teeth portion 2 of another stator department correspondingly.
As shown in Figure 3 and Figure 4, teeth portion 3 is added in each stator department to be formed in same one end.In the stator module,
Additional teeth portion 3 collectively constitutes a complete tooth with teeth portion 2, and additional teeth portion 3 is the supplement to teeth portion 2, and teeth portion 2 is determined positioned at place
In the yoke portion 1 of sub-portion, and additional teeth portion 3 is located at outside the yoke portion 1 of place stator department, so as to be inserted into another stator department
Two teeth portion 2 between.
By the way that two stator departments are combined, (additional teeth portion 3 forms two respective teeth of stator department with teeth portion 2
Structure) circumferentially cross arrangement, conversely speaking, before the combination, in each stator department, have between adjacent two teeth portion 2
Accommodate the space of the additional teeth portion 3 of another stator department, the space between adjacent teeth portion 2 is relatively large, can cause coil
Winding operation it is more convenient, improve production and processing efficiency, on the other hand, two stator department groups in a manner of axially connecting
Close, be easy to directly combination connection, and each stator department is each circumferentially integral type structure, has higher intensity.
Preferably, it is described fixed that another is provided with each stator department, between the adjacent teeth portion 2 of any two
One additional teeth portion 3 of sub-portion.That is, teeth portion 2 alternately circumferentially arranges with additional teeth portion 3, fixed by two
Between sub-portion combination, have in each stator department, between two teeth portion 2 of arbitrary neighborhood and be used to accommodate the attached of another stator department
Add the headspace of teeth portion 3, all there is larger size between two teeth portion 2 of arbitrary neighborhood so as to the two teeth portion 2
Coil winding operation is more convenient.It is of course also possible to the space of teeth portion 3 is only added in the reserved receiving of some adjacent teeth portion 2, separately
Additional teeth portion 3 is not provided between some adjacent fingers 2.
In addition, formed with stopper section 21 in the peripheral side of the radial inner end of the teeth portion 2.As shown in Figure 2 and Figure 4, only
Stopper 21 is formed on the side of 2 circumferential both sides of teeth portion, and stopper section 21 extends towards another adjacent teeth portion 2, described fixed
In sub-component, the distance between stopper section 21 of adjacent two teeth portion 2 is notch size, and stopper section 21 can be used for backstop
The coil being wrapped in teeth portion 2 and additional teeth portion 3, prevents coil from unexpectedly being slid from teeth portion 2.
Especially, the teeth portion 2 and the section phase of the central axis perpendicular to the stator department of the additional teeth portion 3
Together.As Figure 1-Figure 4, it is identical perpendicular to the section of central axis with teeth portion 2 to add teeth portion 3, that is, adds the main body of teeth portion 3
Structure and teeth portion 2 are basically identical, and teeth portion 2 is generally formed into rectangular parallelepiped structure and formed with stopper section 21 described above, additional teeth
Portion 3 is similar structure, and the two is joined together to form as the tooth of the stator module.
Specifically, the yoke portion 1 and the integrally connected of the teeth portion 2, the teeth portion 2 is towards the end face of the additional teeth portion 3
On formed with connecting hole 22, the additional teeth portion 3 is towards being provided with connecting rod 31 (shown in Fig. 5), institute on the end face of the teeth portion 2
State connecting rod 31 to insert in the connecting hole 22, formed with neck on the inner peripheral surface in the yoke portion 1 between two teeth portion 2
11, the radial outer end of the additional teeth portion 3 is inserted in the neck 11.Connecting rod 31 and connecting hole 22 can have respectively one or
Multiple, connecting rod 31 can be inserted into connecting hole 22 in a manner of interference fit or gap coordinate, and additional teeth portion 3 is connected to
Teeth portion 2.In addition, formed with neck 11 on the inner peripheral surface in yoke portion 1, between two teeth portion 2, neck 11 can allow neck 11
The radial outer end insertion of additional teeth portion 3, the circumferentially positioned of two stator departments is realized, avoids two stator departments from relatively rotating.
Formed in addition, the yoke portion 1 and the teeth portion 2 are laminated connection vertically by multiple punchings, the additional teeth portion 3 is logical
Powder metallurgical technique is crossed to be made.As shown in Figure 6 and Figure 7, it is shown that two kinds of different punchings, in the punching shown in Fig. 6, correspond to
Teeth portion 2 is formed in part with through hole, and these through holes correspond to above-described connecting hole 22, in the punching shown in Fig. 7, correspond to
The part of teeth portion 2 does not form through hole, is laminated by punching in the assembly of the yoke portion 1 to be formed and teeth portion 2, is formed in teeth portion 2
Connecting hole 22 be blind hole, do not penetrate teeth portion 2, on the one hand increase the intensity of teeth portion 2, on the other hand can reduce difficulty of processing.
Additional teeth portion 3 is made up of powder metallurgical technique.The structure of additional teeth portion 3 is relatively complicated, and particularly size is relatively small
In the case of, additional teeth portion 3 is difficult to, by casting, therefore, to be made up of the technique of powder metallurgy, specifically, leads to
Cross in the mould of the form fit with additional teeth portion 3 and fill up the auxiliary material such as metal dust and a small amount of adhesive, pass through high temperature
The sintering process of high pressure so that metal powder sintered in mould turns into base substrate, and the base substrate and the shape of additional teeth portion 3 are basic
Unanimously, finished product is can be made into by simple subsequent machining operations, saves processing step.
