Mush winding motor end technology for binding
Technical field
The present invention relates to machine field, be specifically related to the technology that the root straightway carries out colligation in motor stator notch opposing connection group end.
Background technology
Existing mush winding motor section technology for binding structure is made up of single axial tiltedly technology for binding, and as shown in Figure 1, concrete processing step is: 1) non-leading-out terminal: the non-leading-out terminal of arrangement winding end, each groove are with the axially oblique colligation of binding strap together; 2) leading-out terminal: arrangement winding terminal end, winding head buttock line end reason is straight, and put suitable insulating sleeve, the electromagnetic wire paint film is all scraped totally (keeping paint film) by specific length near conduit 10mm place; Peel off the long 15mm of lead wire insulating barrier then; Electromagnetic wire and lead wire are twisted joint together with the arc fusion welding welding again, be inserted in two layers with the overlapping wrapping one deck of insulating tape or with insulated conduit, its length should be greater than wire insulation part 15mm; 3) between the group of arrangement winding with the interpolar wiring, settle wiring point, butt joint length is stayed 20-25mm, all the other cut off, and scrape off electromagnetic wire surface coat of paint, are inserted in insulated conduit (its length is than the long 15mm of joint), weld with arc fusion welding; 4) double-baged with the insulating case pipe box in lead wire and joint after, simultaneously with axially tiltedly colligation of binding strap, lead wire and colligation 2-3 road, joint are being arranged to lead wire and joint, one of all the other groove colligation.The problem that this technology for binding exists is that the root of winding overhang is prone to pine, at motor easy generation wriggling in service, thereby burns the electricity circle.
Summary of the invention
To the problems referred to above, the object of the present invention is to provide a kind of can fastening winding overhang, stop motor and produce the mush winding motor end technology for binding of phase mutual friction because of big electric current winding wriggling.
The present invention adopts such technical scheme to realize; Mush winding motor end technology for binding; It is characterized in that: 1) non-leading-out terminal: the non-leading-out terminal of arrangement winding end; Each groove with binding strap more than the radially colligation twice of root straightway of winding overhang, simultaneously, at every groove winding overhang with binding strap axially tiltedly more than colligation one circle;
2) leading-out terminal: arrangement winding terminal end, winding head buttock line end reason is straight, and put suitable insulating sleeve, and keeping paint film by regulation near conduit 10mm place, all scrape the electromagnetic wire paint film totally in all the other places; Peel off the long 15mm of lead wire insulating barrier again; Electromagnetic wire and lead wire twisted joint use electric arc fusion welding or cold weld together, be inserted in two layers with the overlapping wrapping one deck of insulating tape or with insulated conduit again, its length should be greater than wire insulation 15mm partly;
3) between the group of arrangement winding with the interpolar wiring, settle wiring point, joint length is stayed 20-25mm, all the other cut off, and scrape off electromagnetic wire surface coat of paint, are inserted in insulated conduit, its length is than the long 15mm of joint, with arc welding or cold weld;
4) each groove with binding strap more than the radially colligation twice of root straightway of winding overhang, simultaneously, at every groove winding overhang with binding strap axially tiltedly more than the colligation together.After this end banding finishes, after double-baging lead wire and joint with the insulating case pipe box again, with axially tiltedly colligation of binding strap, in lead wire and each colligation 4-5 road, joint, all the other groove colligations together, the per pass colligation all should be solid and reliable.
The present invention is on the basis of the single axially oblique technology for binding of existing every groove; Be improved at stator rabbet winding portion root straightway is carried out radially colligation and combines to two kinds of processes of colligation to clino-diagonal; Increased more than 1 time to oblique colligation road number average at every fluted shaft simultaneously; Whole fastening winding overhang coil, stop the coil burnout that brings because of end winding wriggling, increased the whole tightness of mush winding motor end; Winding overhang root straightway, is stopped to burn motor because of turn-to-turn short circuit, notch electric leakage radially after the colligation through root, prolongs motor useful life.Mush winding motor of the present invention end technology for binding can reduce motor manufacturing cost, simplified manufacturing technique, raising winding insulation life-span, prolongs motor service time.
Description of drawings
The structure and the shape sketch map of the existing mush winding motor end of Fig. 1 technology for binding;
The structure of Fig. 2 technology of the present invention and shape sketch map;
Among the figure, the 1-winding, 2-is colligation radially, and 3-is tiltedly colligation axially.
Concrete real-time mode
Below in conjunction with accompanying drawing the present invention is done further explanation, but the present invention not only is confined to this.
Embodiment, mush winding motor end technology for binding: 1) non-leading-out terminal: arrangement winding 1 non-leading-out terminal end, each groove simultaneously, are enclosed with the axially oblique colligation 3 two of binding strap at every groove winding overhang with the radially colligation twice of root straightway of binding strap at winding overhang;
2) leading-out terminal: arrangement winding 1 leading-out terminal end, winding head buttock line end reason is straight, and put suitable insulating sleeve, and keeping paint film by regulation near conduit 10mm place, all scrape the electromagnetic wire paint film totally in all the other places; Peel off the long 15mm of lead wire insulating barrier again; Electromagnetic wire and lead wire twisted joint use electric arc fusion welding or cold weld together, be inserted in two layers with the overlapping wrapping one deck of insulating tape or with insulated conduit again, its length greater than wire insulation partly is 20mm;
3) between the group of arrangement winding 1 with the interpolar wiring, settle wiring point, joint length is stayed 22mm, all the other cut off, and scrape off electromagnetic wire surface coat of paint, are inserted in insulated conduit, its length is than the long 15mm of joint, with arc welding or cold weld;
4) each groove with binding strap in the root straightway of winding 1 end colligation 2 twice radially, simultaneously, in every groove winding 1 end with axial oblique colligation 3 two roads of binding strap; After this end banding finishes, after double-baging lead wire and joint with the insulating case pipe box again, with axially tiltedly colligation 3 of binding strap, in lead wire and each joint colligation 5 road, all the other groove colligations together, the per pass colligation all should be solid and reliable.
