Your email address will not be published. Turns Diameter Length Depth It’s calculated by the following formula –, Length in Meters = Count (Ne) × Weight of Yarn (gm) × 1.69, For Filaments with Denier Count (Direct Count System), Length for Meters = (Weight of Yarn in gm × 9000) ÷  Count in Denier. Video Library Core Size. The resistivity of copper at room temperature is 1.724 10–6 -cm. Winding constants. The ferrite toroid is a circular ring magnetic core around which the wire is wounded. It’s the weight of the wound yarn per its volume. Often times. Avoid excess loosened and tightness: Should be taken care. The toroid geometric parameters needed for the wire-length calculation are r i = inside radius = ID/2 h = toroid height and w = toroid width = r o – r i, where r o is the outside radius or OD/2. This simple tool will improve your measurements. NS/NP = VS/VP. Slub – catcher settings: Fixed Blade = Carded – (2.0 to 2.5) x Diameter Combed – (1.5 to 2.0) x Diameter. Winding Calculation. Your email address will not be published. The calculation formula for the amount of wire harness tape winding is derived through theoretical derivation, for the technicians to make the tape quota. 4. Many of us know the famous quote “well-wound is half dyed,” which stands to be true to this day. Another way to measure the slot: - Cut a piece of metal sheet (thickness of 1 mm) in the trapezoidal shape. Why do we need surface speed of the bobbin for calculating production? Save my name, email, and website in this browser for the next time I comment. better. Then the quantities and may be calculated from these fields. Too higher density will result in a package that will hinder the uniform flow of dye liquor. Here is a ferrite toroid calculator to find the required length of the wire. That’s because the weight can change according to the moisture content. Publisher - a knowledge-base repository of textile articles. Example: Let Net Weight of Roll (M) is 1100 lbs, Width of Roll … This site uses Akismet to reduce spam. The actual value may vary depending on winding conditions, etc. = { (900 ×990 ×60 ×24 ×0.85 ×1.09) ÷ (840 ×40 ×2.2046)} kg/day. 5. For Blended yarn = 10 to 15% more settings, Yarn clearer efficiency = 100 present (Faults removed )/(Faults Present)*100, Knot factor = (Total Breaks during winding(at faults))/No of Breaks due to objectional faults, Retained splice strength = Strength of spliced joint * 100 /Strength of parent yarn, Nanotechnology Benefits in Fabric Formation, Environmental Aspects in Textile Industry: Ecological Hazards and Remedial Measures, Winding Tension = 0.1 x Single strength in grams, Optimum spindles / winder N = (4.8 * Y)/S OR, Expected efficiency E = 4500 * Y / (S * N(12 + 98)), Expected production P = (13 Y/(12+98) * C)/winder per 8 hrs in kg, Y = Length / Bobbin (meters.) There are two ways of calculating the length of roll (mathematically speaking a "spiral"), an exact and complex formula derived from integral calculation and an approximate and simpler formula derived from the sum of circumferences of concentric circles. For spun yarns like cotton, the weight variation due to the humidity fluctuations is pretty significant. But as the package builds up and the diameter increases, it’ll rotate less time to wind that same amount of yarn. (To minimize the yam faults). Minimum fault: During winding always should be observed if yam fault become less. electrical coil winders Contact Information Telephone 941-962-8119 FAX 941-745-5602 Business Location Bradenton, FL 34209 Distance - Enter the one-way length of the wires in the circuit in feet. But to account for this error, it’s advisable to add 2% to the calculated winding length, plus extra for lead length. The package density is calculated by the following equations –, Weight of yarn in the package, M = 900 gm, Volume of yarn in the package, V = {(ΠD²h÷4) − (Πd²h÷4)} cm³, = [{(3.1416 × 15) ÷4} × (15.5² − 6.4²)] cm³, Package Density =  Weight of Yarn in the Package (M) ÷ Volume of Yarn in the Package (V). The calculator shown below aims to be a guide in simplifying this process. As you can see, we’ve divided the package into six layers. First, we’ll have to start numbering the layers. Thus, it’s crucial to make sure our soft wound package has a uniform density all throughout. Winding resistance, the resistance of a length of copper wires or bars from one end to the other, is a measure of DC voltage and current and the application of Ohm’s law as follows:. The length is according to your needs, approximately 200 mm and a width of 3 mm on one side and 20 mm on the other side. Also thicker wire causes the total length of wire L, in each coil, to be smaller, since Volume*f=constant=L*A. Calculation of Length of Paper in a Roll. Layer Numbering of Cheese Package (Top View). Generally, Package Density of 0.35 – 0.38 gm/cm³ is Preferable. Contact Information Telephone 941-962-8119 FAX 941-745-5602 Business Location Bradenton, FL 34209 Electronic mail For Quotes or General Information: Steve@production-solution.com. Serrated Blade = 100% more than the above. This factor is crucial to ensure that the yarn/filament package meets our machine’s requirements. Toroid Coil Winding Calculator Use this online tool to calculate the number of winding turns required to achieve the desired inductance with ferrite and iron powder toroidal cores. Calculation of the required rope length based on • Rope length between winch and hoist • Hoist design • Sheave diameter 54 Determination of the drum width based on • Required usable winding capacity • Rope diameter • Drum diameter • Number of winding layers 58 Determination of … Any imperfection left in the soft wound package can result in dire consequences that are not rectifiable. Most of the online calculators enable to find inductance of the coil knowing its winding dimensions and number of turns. oil winder coil winding. Voltage Drop - Choose the maximum percentage of the source voltage drop. The coil internal diameter (ID measured in [mm]) depends on the type of re-coiler of the slitting line. S = Winding speed (meters./min) C = English count. Note: It's recommended to check the ampacity of a wire after doing a voltage drop calculation. By now, I hope you’ve grasped all the concepts regarding winding speed calculation and measuring the package densities and other aspects. This is done with the help of servo motors. Electronic yarn clearer = 3 cm x 3 Diameter. . So, if the quantity of material wound would not be constant, resulting in numerous problems. Coil Physical Properties Calculator. Why can’t we directly input weight instead of length? 14.1.4 Winding resistance The resistance of the winding is where is the resistivity of the conductor material, lb is the length of the wire, and AW is the wire bare area. Now, the winding or production speed of a particular spindle depends on various factors. How to determine winding calculation and what is the objective of winding?The entire parameters along with the winding requirements and objectives. TOP OF THE PAGE. ... cheese winding and (TFO) with calculation formula. Learn how your comment data is processed. Enter the coil length (distance from first to last winding - see diagram). Essential elements of selection of a third party testing lab…, An exclusive information portal on textiles. Thematrix needed for the above loss calculation can be shown to be (8) where is the field everywhere due to a unit current in winding , and is the spatial average over the region ofwinding . 5.Chain winding. the yarn must not be damaged in any way in the winding process.
