Abstract
The invention relates to an alternative insulting structure of a centralized winding motor used for a compressor; the alternative insulating structure includes a welding joint bushing and a slot wedge supporting the welding joint bushing. The welding joint bushing is formed by coiling insulating materials for one to six circles and one end is melt by ultrasonic; the mother plate of the slot wedge is rectangle insulating paper which is folded into a V shape with two longer side wings and shorter folded ridge by three times. The invention has the advantage that the use of the insulating materials is reduced; the welding joint bushing plays the role of alternative insulation simultaneously when protecting the welding joint by being inserted into the slot; besides, the height of the end part of an educing side winding increased by binding the welding joint bushing in the existing insulating structure is reduced.
Description
Technical field
The present invention relevant for a kind of compressor with the phase insulation structure of concentrating coiling electric motor, especially relevant for a kind of can economical with materials and reduce the phase insulation structure of lead-out wire side winding overhang height.
Background technology
In the existing insulation system, the slot wedge shape as shown in Figure 1, 2, cross-sectional schematic such as Fig. 3 show in concentrated coiling electric motor groove, between two stator tooths 91,91 ' is stator slot 95, what place in the stator slot 95 is A phase winding and B phase winding 93,93 ', wherein A, B winding homophase not is inserted with slot wedge 94 in the stator slot 95.Because the folding ridge of slot wedge 94 will reach the effect that phase insulation just can play in slot liner 96 places of the bottom land of stator slot 95, insulating material uses many like this, again and when adopting this slot wedge 94 structures, the plumb joint sleeve pipe must be bundled into lead-out wire side winding overhang, makes motor lead-out wire side winding overhang be higher than anti-lead-out wire side winding overhang height.
Summary of the invention
The present invention uses insulating material and reduces by a kind of new phase insulation structure, and has reduced the lead-out wire side winding overhang height that increases because of the binding soldering sleeve in the existing insulation system.
Use more and motor lead-out wire side winding overhang problem of higher at compressor with the insulating material of concentrating coiling electric motor; the present invention proposes a kind of saving insulating material, have higher insertion intensity, can make motor lead-out wire side winding overhang height and the essentially identical phase insulation structure of anti-lead-out wire side winding overhang height; in this insulation system; in plumb joint sleeve pipe insertion groove; both play a part the protection plumb joint, separated the different phase windings that are placed in the same groove as phase insulation again.
The invention has the beneficial effects as follows that insulating material uses minimizing; also play the effect of phase insulation when protecting plumb joint in the plumb joint sleeve pipe insertion groove, and reduced the lead-out wire side winding overhang height that increases because of binding plumb joint sleeve pipe in the existing insulation system.

Fig. 9 is the whole cross-sectional schematic after slot wedge and plumb joint sleeve pipe insert.
Embodiment
The following Fig. 4 of the present invention is to shown in Figure 9.Fig. 4,5 is plumb joint sleeve pipe 1 schematic diagram, is formed by insulating material coiling 1 to 6 circle, and an end forms welding end 11 with ultrasonic fusing.
Fig. 6,7 is slot wedge 3 schematic diagrames, and its mother metal is a rectangle insulating paper, and is longer through being folded into V font two flanks for three times, and folding ridge place is shorter.Slot wedge adopts V-arrangement can strengthen insertion intensity, makes to be not easy bending when inserting, and V-arrangement also has the effect of supporting the plumb joint sleeve pipe simultaneously.
The interior cross-sectional schematic of groove when Fig. 8 is used for slot wedge and plumb joint sleeve pipe 1.Concentrated coiling electric motor includes a plurality of stator tooths 4, is fixed with winding 6 on the stator tooth 4, and winding 6 is wrapped with slot liner 5.Be plumb joint sleeve pipe 1 between two windings 6.
Fig. 9 is the design sketch after slot wedge 3 and plumb joint sleeve pipe 1 insert.U/V/W is each phase motor coil, and the slot wedge of being invented 3 is opposite with existing slot wedge placement direction in groove, and the V-type of existing slot wedge 3 is pointed to bottom land, and the V-type of slot wedge 3 of the present invention is pointed to notch, and the material use amount is less than existing slot wedge greatly; In the protection plumb joint, also play the phase insulation effect in plumb joint sleeve pipe 1 insertion groove, and reduced the lead-out wire side winding overhang height that increases because of binding plumb joint sleeve pipe in the existing insulation system.
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.
