Embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 3 shows that package assembly schematic diagram of the present utility model.
The utility model comprises stator yoke and is located at several stator tooths in stator yoke, around enamelled wire 5 on stator tooth; Described stator tooth comprises tooth yoke 1 and tooth top 2.
Described tooth yoke 1 is structure as a whole with stator yoke, adopts vertical bar to make reeling after slotting overall stamping-out.
Described tooth top 2 part is provided with link slot 3, adopts Sheet Metal Forming Technology to make.
The salient-pole portion on described tooth yoke 1 top and the recessed pole semi-match of link slot 3.
Institute's tooth top 2 is connected to the top of tooth yoke 1 by link slot 3, two parts connected structure tolerance dimension ties in, and too littlely there will be tooth top position obscission, and too conference affects the utilance of groove.
The connected component of described tooth yoke 1 and tooth top 2 is molded portion 4.
The utility model is, when keeping motor performance, stator core overall structure is divided into two parts---tooth top 2 part and stator yoke and tooth yoke 1 part.
Wherein stator yoke and tooth yoke 1 part are carried out punching press according to straight line to the form (as shown in Figure 3 a) of inserting and are wound into required iron core thickness, tip portion adopts (as shown in Figure 3 b) the overall stamping-out that is staggered to form in addition, the all feasible modes of two parts connected, form a whole stator structure.The design of coupling part should ensure that tip portion can insert, and will ensure bonding strength, in case tip portion comes off simultaneously.Such version reduces the difficulty of technique and mould, and stock utilization brings up to 75% from 24%, saves material cost significantly, also ensure that motor performance simultaneously, improves threading speed and reduces cost of labor.
The salient-pole portion of the utility model tooth yoke 1 and the recessed pole part of tooth top 2 link slot 3 can be exchanged, and the position groove of being namely connected both also can be connected in tooth yoke portion position at tooth top, and vice versa.
The winding mode of the utility model stator core has two kinds: 1) stator yoke and tooth yoke 1 part first carry out coiling, and then tooth top 2 part aforesaid way connects to form an one-piece stator iron core; 2) first by tooth top 2 partial insertion, then coiling is carried out.
A kind of front method is by the restriction of notch, and coiling is unrestricted, but its groove utilance can corresponding reduction; Rear a kind of mode can make full use of groove area, but coiling can limit by notch.
For this reason, in conjunction with the pluses and minuses of two kinds of methods, select suitable notch, make full use of groove area.
The utility model stator core two parts adopt multiple connected mode, the syndeton of described tooth yoke 1 and tooth top 2 is the multiple different connected modes such as dovetail configuration (shown in Fig. 4 a and Fig. 4 b), spoon shape structure (shown in Fig. 5 a and Fig. 5 b), T-shaped structure (shown in Fig. 6 a and Fig. 6 b), trapezium structure (shown in Fig. 7 a and Fig. 7 b), U-shaped structure (shown in Fig. 8 a and Fig. 8 b) or W shape structure (shown in Fig. 9 a and Fig. 9 b), and bonding strength is reliable.
Its advantage of different syndetons emphasizes particularly on different fields, and can select according to actual production, technological feasibility etc.As oat tail groove structure is suitable for perpendicular slotting mode, grooved coordinates intensity high; Dovetail groove syndeton is applicable to the narrower longer and narrower structure of motor teeth portion, and grooved coordinates closely; Spoon shape structure is consistent with in T-shaped version, and just mating part structure is different, one be circular portion (spoon shape) another be straight shape (T-shaped structure), simply, technical elements easily realizes these two kinds of syndetons, is applicable to small machine profile of tooth; U-shaped structure is useful on the larger electric machine structure of motor teeth portion, and coupling part is easily out of shape insertion; W shape respective outer side edges is applicable to larger electric machine structure, and it is equivalent to dual U-shaped structure, and grooved coordinates intensity high, complex structure, but process ruggedness is high.
The tongue and groove of the coupling part difference mainly stock utilization that it causes at tooth top and tooth yoke connected component respectively, but because tip portion area is less, the area ratio accounting for whole iron core is few, rational arrangement, impact is not very large, but can according to the requirement of the difference of electric machine structure and subsequent technique, the position at choose reasonable tongue and groove place.
The utility model is stator core tip portion and all the other tooth yoke part connected structures, adopt slotting punching press winding stock layout technique, the stator core structure be separated not only can reduce the difficulty of technique and mould, stock utilization is brought up to 75% from 24%, clearly save material cost, the notch of technical stator core is little, can ensure the performance of motor; Technique is strong operability, easily realizes, and the high realization that ensure that subsequent technique of dimensional accuracy after coordinating, improve threading speed, reduce cost of labor, production efficiency height waste product is few, substantially increases product and unexpectedly strives power.
The above-mentioned embodiment of the utility model, just illustrates, is not only, and all changes within the scope of the utility model or in equivalent scope of the present utility model are all surrounded by the utility model.
