Abstract
The invention discloses a manufacturing method of a stator. The stator comprises a plurality of tooth portions and a plurality of windings, each tooth portion is provided with a plurality of winding teeth and a plurality of bridging portions which are connected with the adjacent winding teeth. The manufacturing method includes a first step of enabling the plurality of tooth portions to be overlapped together, a second step of winding the windings on the winding teeth respectively, and a third step of cutting off the bridging portions of the tooth portions. Compared with the prior art, the manufacturing method of the stator has the advantages that the windings are wound on the winding teeth, then, the bridging portions of the tooth portions are cut off, therefore, machining efficiency of the stator is higher, and accuracy is better.
Description
[technical field]
The present invention relates to a kind of manufacture method of stator.
[background technology]
Monophase machine in prior art, the stator of monophase machine adopts the method for distributed winding that iron core is wound the line usually, as shown in Figure 1, first winding 91 of coiling and the coil both sides of second winding 92 all stride across the stator slot of some, then first, there are two stator slots 931 that stride across simultaneously in second winding 91 and 92,932, and these two stator slots 931,932 also need other coils that wind the line, in iron core, to have and enough dodge the space with other coils of coiling in order to satisfy two groups of coils of first winding 91 and second winding, 92 coiling backs, the length that just needs first winding 91 and second winding 92 to stretch out iron core wants enough, be that end winding length is wanted enough, when the end winding extension elongation increases, copper consumption will increase, especially the iron core external diameter is big, the motor that iron core thickness is little, the copper cash proportion that is positioned at stator end surpasses 60% of the used copper cash of motor.The coiling of end not only consumes copper material for motor, goes back consumed power, influences electric efficiency.On the other hand, because it is longer to be positioned at the coil extension elongation of end, in order to be fixed in the coil of end, need manually carry out colligation to it, this manufacture method is very backward, has reduced automaticity, and production efficiency is lower.
In motor manufacturing process, for improving the manufacturing efficient of motor and stator, be necessary to provide a kind of manufacture method of new stator to address the above problem.
[summary of the invention]
Main purpose of the present invention is to provide a kind of manufacture method of high efficiency stator.
For achieving the above object, the present invention can adopt following technical scheme: a kind of manufacture method of stator, described stator comprises some tooth portions and some windings, each tooth portion has some coiling teeth and connects some bridge parts of adjacent described coiling tooth respectively, described manufacture method step is as follows: the first step, and some teeth portion mutual superposition is together; In second step, described winding is wound in respectively on the described coiling tooth; The 3rd step, the bridge part of the described tooth of severing portion.
Compared with prior art, the beneficial effect of the manufacture method of stator of the present invention is: on the coiling tooth, stamping-out falls the bridge part of the tooth portion of tooth portion then, makes the stator working (machining) efficiency higher by first coiling winding, and precision is better.

Fig. 2 is the preceding structural representation of the stamping-out of stator of the present invention.
Fig. 3 is partial enlarged drawing in the center line shown in Figure 2.
Fig. 4 is the structural representation behind the stamping-out of stator of the present invention.
[embodiment]
Stator of the present invention 100 is used for monophase machine (not shown), the yoke portion 30 that it comprises some teeth portion 10 and the winding 20 in the tooth portion 10 and is installed on tooth portion 10 peripheries.
To shown in Figure 4, the manufacturing invention step of stator of the present invention is as follows as Fig. 2: the first step, and each tooth portion 10 is the sheet monolithic construction, described tooth portion 10 has some coiling teeth 11 and connects some bridge parts 12 of adjacent described coiling tooth 11 respectively.Coiling forms installation portion 112 respectively on the tooth 11, and it is on the track of a circle in the center of circle that some installation portions 112 are distributed in tooth portion 10.Described bridge part 12 comprises stamping-out portion 121 and is positioned at stamping-out portion 121 both sides and the connecting portion 122 of connection coiling tooth 11.The cross-sectional area of stamping-out portion 121 is less than the cross-sectional area of connecting portion 122.Some teeth portion 10 mutual superposition together.
As shown in Figure 2, yoke portion 30 is the sheet monolithic construction, and it comprises inner ring 31, inwardly protrudes out groove 33 between some boss 32 and the boss 32 at inner ring 31.
In second step, winding 20 winds the line respectively on coiling tooth 11.Some yokes portion 30 is superimposed, and groove 33 is accommodated installation portion 112, and installation portion 112 outer surfaces of tooth portion 10 are close to yoke portion 30 inner rings, 31 surfaces.Tooth portion 10 and yoke portion 30 fit together by the mode of pressing.
The 3rd step, to tooth portion 10 processing of stator 100, the bridge part 12 of severing tooth portion 10, its stamping-out portion 121 is by complete stamping-out, and some coiling teeth 11 only are connected with connecting portion 122.In other embodiments, connecting portion 22 also can be punched, and is not connected with coiling tooth 11.
On the coiling tooth, stamping-out falls the manufacturing step of bridge part of the tooth portion of tooth portion then, can make the stator working (machining) efficiency higher by first coiling winding, and precision is better.
