In order to maintain constant wire resistance, an effective wire tension control scheme is essential. That is, the wire tension should be controlled to stay around a constant level so that the cross section area of the enameled wire will not have significant variations during the winding process. In addition, one of the most important issues in automatic motor winding is the resistance of the enameled wire, whose value should not have any significant deviation before and after the winding process. Without proper control in wire tension, tidy winding of the enameled wire cannot be accomplished. In a typical winding process of an automatic motor winding system, the enameled wire is driven by the rewind roll. Results of the winding experiments verify the effectiveness of the proposed wire tension control scheme. Moreover, due to the fact that the motion of the unwind roll is affected by the motion of the enameled wire, the estimated wire speed information is exploited in the design of the tension control scheme to lessen the lag phenomenon. In particular, an iterative learning sliding mode control scheme for wire tension control is developed in this paper, while a disturbance observer is employed to estimate the wire tension for the implementation of sensorless wire tension control. In order to cope with the aforementioned problems, this paper conducts an in-depth study on active wire tension control of automatic motor winding machines. However, as the winding speed increases, these passive devices may not be able to react quickly enough to maintain constant wire tension and may cause the enameled wire to tremble. Most commercial automatic motor winding machines use passive devices such as a dancer arm or a hysteresis brake to adjust the wire tension. The surface of NSW ® Winding Wires which are insulated with PE2 have a thin outer layer of polyamide (PA) for surface protection.One of the most crucial factors that affects the winding quality in an automatic motor winding process is the regulation of wire tension. The insulation wall thickness depends on the operating voltage.įor voltage above 3kV, recommendation is to use a semiconducting layer (HL) between the copper conductor and the insulating sheath. Increased heat resistance is achieved by cross-linking the polyethylene. PE2-insulated winding wires can be used in submersible motors operating at higher voltages as well and at temperatures of up to a maximum of 90 ☌. PVC-insulated winding wires are generally used for voltages up to 1,000 V and at temperatures up to 75 ☌.
