Problems solved by technology

For the motor, the winding at the end not only consumes copper, but also consumes electric energy, which affects the efficiency of the motor
On the other hand, because the coils at the ends protrude longer, in order to fix the coils at the ends, they need to be bound manually. This manufacturing method is very backward, which reduces the degree of automation and lower production efficiency.

Embodiment Construction

[0011] The stator 100 of the present invention is used in a single-phase motor (not shown), and includes a plurality of teeth 10 , windings 20 wound on the teeth 10 , and a yoke 30 mounted on the periphery of the teeth 10 .

[0012] like Figure 2 to Figure 4 As shown, the manufacturing steps of the stator of the present invention are as follows: in the first step, each tooth portion 10 is a sheet-like integral structure, and the tooth portion 10 has a plurality of winding teeth 11 and connects adjacent winding teeth respectively. 11 of several bridging portions 12. Mounting portions 112 are respectively formed on the winding teeth 11 , and several mounting portions 112 are distributed on the track of a circle with the tooth portion 10 as the center. The bridging portion 12 includes a punching portion 121 and connecting portions 122 located on two sides of the punching portion 121 and connecting the winding teeth 11 . The cross-sectional area of ​​the punching portion 121 is...

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】 [0001] The invention relates to a manufacturing method of a stator. 【Background technique】 [0002] In the single-phase motor of the prior art, the stator of the single-phase motor usually adopts the method of distributed winding to wind the iron core, such as figure 1 As shown, both sides of the coils of the first winding 91 and the second winding 92 of the winding all span a certain number of stator slots, then the first and second windings 91 and 92 have two stator slots 931, 932 that span simultaneously, The two stator slots 931, 932 also need to be wound with other coils. In order to meet the requirements of the first winding 91 and the second winding 92, the two sets of coils must have enough avoidance space in the iron core to wind other coils. It is required that the length of the first winding 91 and the second winding 92 protruding from the iron core should be sufficient, that is, the length of the end of the coil should be sufficient. When the e...
