Abstract
The invention relates to a slot wedge of centralized winding motor used for a compressor which includes a first side surface and a second side surface formed by being integrally bent with the first side surface; bent folding ridges are arranged between the two side surfaces; one side of the folding ridge on the first side surface is provided with a first top wing which is bent up opposite to the first side surface; the other side is provided with a bottom wing which is bent up opposite to the first side surface; the side of the folding ridge on the side surface same with the first top wing is provided with a second top wing which is bent up opposite to the second side surface and the other side is provided with a second bottom wing which is bent up opposite to the second side surface. The slot wedge has the advantages of leading the alternative insulation to be more reliable and improving the technique performance of the slot wedge when being inserted.
Description
Technical field
The present invention is relevant for the slot wedge of a kind of compressor with concentrated coiling electric motor, especially relevant for a kind of phase insulation reliability height, the slot wedge that insertion process is good.
Background technology
Tradition is concentrated coiling electric motor as shown in Figure 1, and motor 90 includes three-phase coil U, V, W (91,92,93), and the stator slot 95 between 94, two stator tooths 94 of stator tooth is placed slot wedge 96 in the stator slot 95.Each traditional slot wedge 96 includes V-shaped first side and the second side (not shown) mutually that link together shown in Fig. 2,3, and first flank 961 that separates later in first and second sides respectively and second flank 962.This kind slot wedge 96 has following two major defects.The first, because the contact gear ratio of the junction of first side and second side and stator slot 95 bottoms is weak, therefore when copper factor is higher, between the out-phase coil of trench bottom, cause phase fault easily.The second, because when inserting slot wedge 96 in the stator slots 95, separate with respect to direction of insertion two side, is easy to generate bending when therefore inserting, the manufacturability during slot wedge 96 insertions is relatively poor.
Summary of the invention
One object of the present invention is to provide the slot wedge of a kind of compressor with concentrated coiling electric motor, and this slot wedge makes phase insulation more reliable.
Another object of the present invention is to provide the slot wedge of a kind of compressor with concentrated coiling electric motor, this slot wedge can improve the manufacturability when inserting.
To achieve these goals, the invention provides the slot wedge of a kind of compressor with concentrated coiling electric motor, it comprises one first side and second side that forms with the first side one bending, be the folding ridge of bending between two sides, a side of folding ridge has first roof limb that bends up with respect to first side on first side, opposite side has first end wing that bends up with respect to first side, a folding ridge side identical with first roof limb has second roof limb that bends up with respect to second side on second side, and opposite side has second end wing that bends up with respect to second side.

Embodiment
With reference to figure 4,5, it is respectively solid of the present invention and schematic top plan view.The present invention is the employed slot wedge 10 of a kind of concentrated coiling electric motor, it comprises one first side 11 and second side 12 that forms with the bending of first side, 11 one, two sides 11, folding ridge 13 for bending between 12, a side of folding ridge 13 has first roof limb 111 that bends up with respect to first side 11 on first side 11, opposite side has first end wing 112 that bends up with respect to first side 11, the side that folding ridge 13 is identical with first roof limb 111 on second side 12 has second roof limb 121 that bends up with respect to second side 12, and opposite side has second end wing 122 that bends up with respect to second side 12.
With reference to figure 6, slot wedge 10 of the present invention is exactly to form by section bar bending shown in Figure 6.As shown in Figure 7, coiling electric motor 20 includes three-phase coil U, V, W (21,22,23), and the stator slot 25 between 24, two stator tooths 24 of stator tooth can be placed slot wedge 10 in the stator slot 25.In use, the folding ridge 13 of slot wedge 10 can be inserted stator slot 25 towards stator slot 25 directions.Because the existence of first roof limb 111 and second roof limb 121 makes slot wedge 10 be strengthened with contacting of stator slot 25 bottoms,, between the out-phase coil of trench bottom, also be not easy to cause phase fault even therefore when copper factor is higher.In addition, because the existence of folding ridge 13 is arranged between first side 11 and second side 12, when slot wedge 10 inserts in the stator slot 25, folding ridge 13 is introduced into, therefore first side 11 and second side 12 separating have just been avoided with respect to direction of insertion, make to be difficult for when inserting producing bending, improved the manufacturability when slot wedge inserts.In sum, purpose of the present invention all realizes.
Known to those skilled in the art, drawings and Examples of the present invention are only for illustrating that function of the present invention, structure and principle should not become the restriction in the present invention's understanding; Simultaneously, purpose of the present invention all realizes.The foregoing description may be had some change under the situation that does not break away from the principle of the invention, so protection of the present invention should be as the criterion with the scope described in claims.
