Abstract
The invention relates to a binding technology which is applied to line segments at the root of a winding end part at a motor stator notch. The binding technology is characterized in that the combination of a radial binding process with an inclined radial binding process is applied to the line segments at the root of the winding end part at the motor stator notch on the basis of an existing single axial inclined binding technology for each notch, thus integrally fastening coils of the winding end part, avoiding the coils from being burnt due to winding peristalsis at the end part, and strengthening the integral tightness of a mush winding motor end part; meanwhile, after the line segments at the root of the winding end part are subjected to the radial binding of the root, a motor is prevented from being burnt due to turn-to-turn short circuit and notch leakage, and the service life of the motor is prolonged. The binding technology is utilized to reduce the manufacturing cost of the motor, simplify the manufacturing processes, improve the insulation life of a winding, and prolong the use time of the motor.
Description
Technical field
The present invention relates to machine field, be specifically related to the technology of carrying out colligation at motor stator notch opposing connection group end root straightway.
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, length is all scraped the electromagnetic wire paint film totally (keeping paint film near conduit 10mm place) in accordance with regulations; 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, lead wire and joint simultaneously with axially tiltedly colligation of binding strap, are being had lead wire and colligation 2-3 road, joint, all the other groove colligations together.The problem that this technology for binding exists is that the root of winding overhang is easily loose, at motor easy generation wriggling in service, thereby burns the electricity circle.
Summary of the invention
At 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 uses 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 near conduit 10mm place in accordance with regulations, 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 uses binding strap more than the radially colligation twice of root straightway of winding overhang, and is simultaneously, axial tiltedly more than the colligation together with binding strap at every groove winding overhang.After this end banding finishes, after being double-baged with the insulating case pipe box in lead wire and joint 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.
