It should be recognized that the wire needs to enter in a possibly flat angle into the winding space.Please help improve this article by adding citations to reliable sources.Find sources: Coil winding technology news newspapers books scholar JSTOR ( July 2016 ) ( Learn how and when to remove this template message ).
Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones. The shape and dimensions of a winding are designed to fulfill the particular purpose. Parameters such as inductance, Q factor, insulation strength, and strength of the desired magnetic field greatly influence the design of coil windings. Coil winding can be structured into several groups regarding the type and geometry of the wound coil. Mass production of electromagnetic coils relies on automated machinery. The ratio of the area of electrical conductors, to the provided winding space is called fill factor. ![]() To achieve higher fill factors, rectangular or flat wire can be used. This increases the efficiency of the electrical device and an improved heat conductivity of the winding. For best packing of round wires on a multi-layer winding, the wires in the upper layer are in the grooves of the lower layer for at least 300 degrees of the coil circumference. Download marathi movie songsThe wires occupy a dense package which is called orthocyclic winding. The opposite of this would be a random wire structure within the winding space, which is called wild winding. ![]() It is characterized by low demands for machinery and operator and can be wound with very high speeds. Wild windings are mostly applied in contactor - and relay coils, small transformers, Ignition coils, small electrical motors, and generally devices with relatively small wire gauges up to 0.05 mm. Achieved fill factors with the use of round wires are about 73 to 80 and are lower compared to orthocyclic windings with 90. Owing to the direction of movement from layer to layer changing between right-hand and left-hand, the wires cross and locate themselves within the gap of the layer underneath. If the number of layers exceeds a certain limit the structured cannot be maintained and a wild winding is created. This can be prevented with the use of a separate layer insulation, which is needed anyway when the voltage difference between the layers exceeds the voltage strength of the copper wire insulation. Mogalirekulu rk shanthi episode 1When the winding has been placed around the coil body it will meet with the previous positioned wire and needs to make a step with the size of the wire gauge. The winding step can occupy an area of up to 60 degree of the coil circumference for round coil bobbins and takes one side of rectangular coil bobbins. The area of the winding step is dependent on the wire gauge and coil bobbin geometry. Overall, the first intruding wire mainly determines the location and quality of the winding step.
