coil winding machine adopts orthocyclic winding pattern. 7%) for round wires. Traditional winding processes can be categorised into linear winding, needle winding, flyer winding, or pull-in winding . DETAILED DESCRIPTION OF THE INVENTION. SMT utilizes state of the art winding equipment to produce a multitude of electromagnetic coils. Innovative coil winding processes are presented in [21]. The coil has a number of layers with the length or width fixed to the bobbin. These pictures represent a rebuilt version of prototype 2 of the orthocyclic coil winding machine. This pattern goes on continuously for every turn wound and every layer. L. Orthocyclic winding. To compensate, aluminum windings cross-section must have 1. 3. L. The orthocyclic coil winding machine comprises a bed 1 (FIG. Given: Coil width: should be 9 mm // 150 turns, coil inner diameter 8mm. 68 x 10-8) = 1. However, its impact on winding parasitics, i. energy. Acme Mechatronics, Inc. Orthocyclic winding of Inverter UPS coil. Our engineer Yuri is happy to show you an example of an orthocyclic wound coil: In terms of the form factor, coils can be round, oval, square, rectangular or even bent. The best use is found once the winding is found to be parallel to the coil flange for most of its circumference. The disadvantage of this method is its lower packing factor. It is best for the round wires in which the winding of the upper layer is placed within groups, and it is available with the help of the lower layer. All. 6 times higher than copper’s resistivity. G. com 0208 6596977 sales@recoilltd. 3 mm and a maximum winding width of 9 mm shall be calculated. Recoil Ltd are experts in coil winding of custom coils, solenoids, transformers, toroidal and orthocyclic windings and precision wound parts. e. On account of the smaller winding length the ratio of resistance R to inductance L is smaller than in non-orthocyclic coils; the quality factor Q = coL/R is therefore relatively high. Coils can be fully encapsulated if needed. Published in: 2015 5th International Electric Drives Production Conference (EDPC) Article #: Date of Conference: 15-16 September 2015 The Non-Orthocyclic Winding ; The pattern is most common in winding coils. This version is an exact replica, except for the counter. Smallwood Inc. orthocyclic coils is that less wire of a given gauge is needed to wind a coil with a given number of turns. 1K views 7 years ago. Our Winding Capabilities include: Linear winding styles – precision linear winding, orthocyclic winding, bobbin winding, layer winding, self supporting coils. , the winding capacitance, ac resistance, and leakage inductance, has not been systematically investigated. 7%) for round wires. The winding diameter at the winding base measures 8 mm. Toroidal winding styles – precision toroidal winding, progressive winding. 6 times larger and diameter must be 1. The original was designed and built by Philips in the mid 1960’s. This type of winding structure creates an optimal fill factor (90. 045. OVERVIEW. , the winding Orthocyclic coilwinding machine original version built approx. 65 x 10-8) / (1. That means Aluminium wound coils are larger than an. Extensive experience in winding. method and suitable winding machines are described by Querfurth (1958). However, its impact on winding parasitics, i. Orthocyclic winding. 6. Results of orthocyclic windings are simulated with and without grooves on the coil body surface and demonstrate the positive influence of grooves for an accurate orthocyclic winding picture. . An orthocyclic winding design for a round coil with 150 windings, a wire diameter of 0. Orthocyclic winding with a needle winder is therefore only partly possible for these winding tasks. As the winding continues, its direction changes leaving the width or the bobbin layer intact. However, its impact on winding parasitics. 621. Aluminum’s resistivity is 1. 1967, rebuilt version 2008. The orthocyclic method was selected because of its high density, its complete pattern regularity, and its basic simplicity. SFC has a lot of experience and knowledge in winding and bending coils. 04 – 3 mm Parasitics of Orthocyclic Windings in Inductors and Transformers Zhan Shen, Student Member, and Huai Wang, Senior Member Abstract— The orthocyclic winding in magnetic compo-nents is common in both laboratory prototyping and mass-production, especially for round wires with curved edges. has many years of experience and expertise in manufacturing winding styles of all types. LENDERS *). An orthocyclic winding should be preferred, due to the up to 25% higher fill factor [2]. We have the following capabilities: Orthocyclic winding with a high fill factor (>95%) Coil winding with one, two or more wires in parallel; Single and multi-layer ; Many different shapes; Outside dimensions 1 – 600 mm; Wire size 0. 1) which mounts a turntable 2 with several mandrels 3 installed radially thereon. Coil winding refers to various processes involved in forming a continuous copper wire (usually circular in cross-section) into a complete coil or series of connected coils for integration into a machine stator or rotor. The Orthocyclic winding pattern can be considered as parallel winding. However, its impact on winding parasitics, i. Show. The best volume use is found when the winding is parallel to the coil flange for most of its circumference. e. Precision wound coils can be produced using various wire gauges and materials. The turn is wound in its location and immediately wire is shifted to the next location for the next turn within the fraction portion of the turn. Orthocyclic winding of coil to achieve high turns density in given space of winding. Orthocyclic winding in magnetic components is common in both laboratory prototyping and mass production, especially for round wires with curved edges. Orthocyclic winding is referred to as a type of winding structure which creates an optimal fill factor for the round wires. When the winding has been placed around the coil body it. An Orthocyclic winding, a type of winding, constructs an optimal factor. , winding capacitance, ac resistance, and leakage inductance, has not been systematically investigated yet. The overmoulding of coils (IP68) under vacuum with epoxy is also one of our specialities. 0208 6596977 sales@recoilltd. KUK Group is an expert at winding coils orthocyclically. com Aluminium/Copper = (2. The windings of the upper layer need to be placed into the grooves provided by the lower layer. Before the lamination is wound , insulation between the plate and wire is inserted into the grooves to. Structure of a coil with an even number of turns per. Abstract—The orthocyclic winding in magnetic compo- nents is common in both laboratory prototyping and mass- production, especially for round wires with curved edges. 16---~---~ Orthocyclic winding is a method developed by Philips for obtaining coils whose turns are stacked in the most compact fashion possible. The windings of the upper layer need to be placed into the grooves provided by the lower layer. Such coils have certain particularlv good proper- synchronous machine and asynchronous machine , was created and is shown in Figure 1. e. At the required distance from one of the mandrels 3 is situated a winding spindle 4 driven by a drive unit 5. The orthocyclic winding in magnetic components is common in both laboratory prototyping and mass production, especially for round wires with curved edges. 3. したがって、ニードルワインダーを使用したオーソサイクリックワインディングは、これらのワインディングタスクでは部分的にしか可能ではありません。 THE ORTHOCYCLIC METHOD OF COIL WINDING by W. The turns are carefully wound onto each other in a specific layer. 26 times of copper windings to offer the same conductance. The windings of the upper layer needs to be placed within the grooves which is provided by the lower layer. S. 6) Small variation in inductance and self -capacitance Orthocyclic winding structure creates an optimal fill factor (90. Figure 2 shows the orthocyclic pattern of a coil wound for a thermal probe .
