Whether it is stator winding or rotor winding, whether it is soft winding or hard winding, its end will be bound in the process of production and manufacturing; theoretically, the purpose of binding is to ensure that the relative position of winding and winding, winding and insulation, winding and associated parts remains unchanged, and it is conducive to the curing effect of winding after dipping paint and drying.
In order to achieve this purpose, the thermal shrinkable insulating tape or binding rope will be used when binding the winding, so as to ensure that the winding end is a relatively solid whole after being dipped in paint and dried. However, the heat shrink ability of the binding tape has a certain range, so a certain tension force should be ensured in the binding process.
What should be emphasized here is that for the binding and fixing of the lead wire, on the one hand, it is necessary to ensure that the lead wire cannot be moved at will after binding, and on the other hand, the connection part between the lead and the line will not be pulled by the later processing. In view of the above reasons, the binding of winding end must be standardized, not just stay in the form of winding.
