Given that the PFSA 103E of the hollow core coil Dmin=200mm and the diameter of the full coil Dmax=1200mm; The maximum value of linear speed Vmax=90m/min, and the maximum tension setting Fmax=50kg (approximately equal to 500 Newton); Reduction ratio i=9; The speed limit is as follows: V=π * D * n/i (V-line speed, D-coil diameter, n-speed, for the winding motor)=>The winding motor has the fastest speed when the core diameter is empty. So: 90=3.14 * 0.2 * n/9=>n=1290r/min.

·Because we know that when the frequency converter operates at low frequencies, the characteristics of AC asynchronous motors are not good, the activation torque is low and nonlinear. PFSA 103E , during the entire winding process, it is necessary to avoid the winding motor working below 2HZ as much as possible. Therefore, the winding motor has a minimum speed limit. The calculation is as follows: for a four pole motor, its synchronous speed is: n1=60f1/p=>n1=1500r/min (f1- is the rated frequency, p – is the number of poles, n1- synchronous speed) 2HZ/50HZ=N/1500=>n=60r/min. When the maximum roll diameter is reached, the lowest speed during the entire winding process can be calculated V=π * D * n/i=>Vmin=3.14 * 1.2 * 60/9=25.12m/min. When controlling the tension, the speed should be limited, otherwise speeding may occur. Therefore, speed limit is necessary
