Motor network both stator winding and rotor winding, either soft or hard windings, the yield in the process of manufacturing of port will make the necessary binding; From theoretical analysis, the purpose of the tie is to ensure winding and winding, winding and insulation, winding and associated parts stick to the same relative position, and help to winding varnished drying after curing effect. Binding in order to achieve this goal, winding will choose hot shrinkage insulating bind or binding rope, to ensure the winding varnished after drying, the end is a relatively consolidate all. But tie belt thermal shrinkage is a certain size, therefore in the process of binding shall ensure that there is a certain tension force. Also want to emphasize here, on the issue of the wire bundle and fixed, on the one hand, be sure to lead to casual mobile after binding, on the other hand also make sure that the lead and the line connecting the pull of the part will not be late processing. In view of the above reasons, the binding of winding ends must specification, not only stay in the form of winding. High voltage motor end binding using analytical due to motor winding has the same phase and phase-out, end two adjacent coil will be attract each other between bars and exclusion effect, to prevent force of displacement due to the effect, so be necessary to end fixed, in the side gap between adjacent winding bar, choose the thickness and gap intrusive similar polyester cord tied tightly. Now, high voltage motor stator more chooses VPI and leaching process, its insulation structure is tape wound coil, coil end with polyester glass rope tie, coil and the hoop with rope wire binding, but also cannot too tight, in order to prevent the touch the part of the present insulation damage in varying degrees, lower the insulation performance. When the coil heating wire according to the requirements of process, to soften near the nose end coil insulation. This makes insulation damage, affects the service life. Due to large pitch high speed motor, electrode spacing is also big, therefore, a common stator winding end long size, large bell mouth etc. Characteristics. Also some choose, large and small coil end undulate area round coil, the space between the upper and down, very small. Therefore can hoop on the coil end insulation on a thick layer 4 - flat pack5 mm polyester felt, between the coil and liner effect. Because of polyester felt soft and has a certain amount of compression, can make the wire tie the coil insulation are no longer end of the hoop sag, also increases the binding of touch area, ensures that the coil hoop closely touch with end, winding contain paint after curing, would end in radial and tangential fixed.
