These machines are practical tools in the electronics industry and many other sectors such as electrical motors, transformers, generators, electric vehicle batteries, and hybrid cars. It consists of a stationary axis and a rotating axis. The rotary axis holds the material wound onto the cable core, while the stationary axis winds it accurately. 

The primary purpose of these winding machines is to wind wire on the tube former mechanically. When it comes to a custom-made automated winding solution, this type of winding machine is helpful in locations where there is a requirement for such customization. It offers the feature for one of the coils or the undersized amount clusters of the Coil. If you enjoy a resolution for customized coils, then CNC windings are most reasonable in such terms.

3. Armature Winding Machine

An armature winding machine, a piece of equipment, works on electrical appliances’ production. It has many characteristics, such as automatic feeding, automatic tensioning, and it can wind and unwind any altitude of wires. It takes the core, inserts it into a coil, and adds the necessary backing material to make it strong enough for use. 

The main work of this machine is the purpose of incorporating the loops on an electric motor to produce electrical power through induction. Many manufacturers use this device to make large quantities of electric motors, horizontally and vertically mounted in many industries, including automotive, construction machinery, aerospace, and mining equipment. 

It is a winding machine that enables standard and customized central field coil winding conditions. The device comes with hook commutators, and in some devices, it may also provide an auto wire cutting and hooking option.

4. Transformer Winding Machine

A transformer winding allows wind coils on a ferromagnetic core to assemble transformers. It is known for creating a secondary winding for an electrical transformer. It is a valuable tool when it comes to constructing high-voltage transformers.

The device dispatches electricity over prolonged lengths. The number of turns in each coil decides how much strength can be assigned safely over a provided term. These machines are usually automatic and can be computer-controlled and helpful in manufacturing power transformers, distribution transformers, power reactor/converter stations, and switchgear.

Working Principle of Coil Winding Machine:

It is conducive if we know about the principle of coil winding machines to learn about it better. When we talk about the principles of this application, then minimizing the materials and volume and efficient coil is of utmost importance.

In the device, it is a fill factor that indicates the ratio of the area of the electrical conductors in the winding space. It requires rectangular flat wires for the fill factors as the round ones are often gaps. 

In this procedure, it requires to hold a high fill factor with basic and Packaging of wire so that it can reduce the air space. It increases the efficiency of any electrical instrument and enhances heat conductivity.

In the multilayer machine, the bottom wires in the upper layer molded in the lower layer levels for about 300 degrees clipped the coil. The wires in the Ortho cyclic winding are filled densely. And in the wild winding, it remains as a friend of a structure within the given space of the winding.

Wild Winding:

When we talk about winding, then in this type of wherein the random wire places directs to a wider dispersal which results in the wire length on the coil body. It indicates why wires’ dispersal leads to a wide spectrum of electric ring resistances.

It is a popular device for mass production, and it doesn’t have a high demand for machinery and operators that require high speed as their chances of damage. This type of wiring is applied to applications such as ignition coils, relay coils, small transformers, small electrical Motors, and devices that don’t have large wherein the gauges as it is best for works for gauges that are up to 0.05 mm.

Helical Winding:

When we talk about the spiral binding method of wiring, the wiring is placed in a spiral way in every layer of the machinery. The direction of the moment changes from layer to layer, and often, these wires are found crossing the layers underneath within the given space. In this, a wire compass, the descending layer never brings extant. If the device’s layer is accessed, it becomes tough for the structure to maintain, and it may also create a wild winding.

Orthocyclic Winding:

An Orthocyclic winding, a type of winding, constructs an optimal 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. 

It is a process that helps position the wire in parallel to the coil linkage, which positions around the coil body. The process requires the arranged wire to step with the proportions of the earlier wire gauge. The wire inhabits a spot after 60 degrees of the coil conference. It happened with the round coin, and the coil takes one side of the rectangular coil, and the winding step depends on the coil geometry and wire gauge.

Process of Winding:

Let us focus now on “how is winding done.” Some of the processes that are involved in the overall process of winding are:

1. Linear Winding:

It is a technique in which the winding production takes place with spiralling the wire on a coil constructing appliance, component, a rotating coil body, and coil carrying. The wire comes from a supplier roll, and it contains around 400 kg of copper wire that is enamelled and filled with the help of a guiding tube before starting the whole process of winding the wire mounts on coils to clamp the device.

The element gets retained to disperse the guiding two utilizing a twisted slot on the coil with the linear laying action or movement. The apparatus accomplishes the rotary action with the help of computer-controlled Engines. The transverse axis of the wire assists the tube from one cycle to the rotation axis as per the wire’s diameter.

It estimates the coiling diameter. It takes place to get the pace during the complete winding procedure. The process scales the segments required to curl on the spiral device, and it combines with drive and spindles that support generating the turning action. With the help of the rotational axis and transverse axis, it operates in secret, synchronizing the whole winding process to bring the wire into the winding area evenly.

2. Flyer Winding:

In this method, dispersal is created with the assistance of a feeding wire/roll/nozzle presented to a flyer. It pivots at a specific space from the coil, and the wire feeds with the assistance of a flyer shaft. The winding process requires components fixed at the inside of the flyer; it is known as mandatory when fixing the wires outside the flyer.

It requires a successive winding method for the fixation of the wire for the rotating indexing tables. It includes wire clips of wire deflection and the circumference of the table. It enables a force along and fixation. With the help of this method, it permits the component to adjust, which permits it to diverge the deposition of the wire in the device’s wire clip.

3.  Needle Winding Technology:

It is a winding technology advantageous in curling the pole shoes critical to commuting the multiple three-phase Machines. These motors are shielded with insulation that sustains the course of the turn with the needle winding technique. A needle with a nozzle is found at the right angle to the movement.

It then travels in a lifting motion and through the stator packs with the help of the groove channel and goes straight or with the two adjacent poles of the engine to enable the wire to the preferred place. It then rotates at a turnaround pinpoint of the winding with the assistance of one tooth pitch. It occurs to retain the prior rotation output in reverse order.

It creates a layer arrangement, and when it comes to drawbacks of this technology, it drives support between two bordering poles with the extent of nozzle diameter. The size of the nozzle is around the diameter of the winding wire, so it doesn’t fill the space between the two adjacent poles.

4. Toroidal Core Winding Technology:

In this winding process, the magnetic core braces on the holding spout two functions slow Rotary movement along with the three rubberized moments of connection.  

It arranges to store ring orbital wheel at 90 degrees to the magnetic core, which comes at the circumference and introduces it to the epicenter of the magnetic/toroidal core—the wire coils roughly the storage ring of the wires so that they can shut again.

The end of the wire from the accumulator fixes to the core. It takes place as per the required amount in the wire accumulated to create the wounds for the toroidal core.

It produces a winding process that distributes alongside the circumference of the toroidal core with the support of the course of the wire accumulator ring and the toroidal core. It needs the accumulator to open again to release the wound toroidal core after the fulfilment of the procedure. The machines in this technology are partly automated as the wires are not fixable in the toroidal core from the start.

What are the types of winding in a transformer?

Layer windings:

In this winding, the insulated conductors are arranged axially around the windings. Moreover, the device also places the turns next to each other. It comes in single and multi-layered forms wherein the single-layered winding machine winds only one turn around the core limb. On the other hand, the multi-layered binding can turn insulated conductors around the wound into several layers. 

The insulated conductors separate from each layer by using oil ducts, solid insulation, and sometimes using both types of elements to separate the conductors. Whether it is a small and medium-sized transformer, this instrument is beneficial for both.

Helical winding or spiral winding:

It is a multi-layered winding tool with several conductors when we talk about winding. The conductors in this device are parallel, and also form single turns that wound along the axial direction. It places the wounds with spacers that come between the adjacent turns.

It has a resemblance to a corkscrew when it comes to construction. These devices are helpful even in low voltage and high currents. As current flows within the parallel conductors, the voltage remains the same in each turn.

However, the magnetic field at Parallel Conductor links may not remain the same as it distributes flux evenly between the conductors. The device then goes on ascending the uneven currents in the conductors. We can use the transportation technique in this device by equalizing the magnetic field by Linking each conductor to minimize the currents in the conductors. These devices are known for their robustness and significant factor.

Disc winding:

It is a transformer coil winding machine with several connected discs of conductors. The disc in this device winds multiple turns of insulated conductors that connect in a series to form a disc winding. With the help of spacers, the disc diverges from the adjacent disc—the disc, setup by looping single and several parallel conductors.

When we talk about the difference between helical winding and disc winding, helical windings only have one turn for every disk in the Parallel Conductor. In this winding, there are several turns in each disc. The Disc type windings that the Transformers require are above 25 KV. These devices are known for their robustness.

Foil windings:

Foil winding is a type of Transformer winding machine with the exterior of copper or aluminum sheets. These sheets spiraled numerous times to form multiple-layer windings in a spiral formation. This type of device helps support the high capacity Transformers in which the current ranges from 12 to 600 A. It includes the windings using single and multiple sheets in the parallel wound.

The foil winding machines help wind many long continuous conductive wires on a bobbin. These conductors are then used to make the various inductor coils required to construct transformers, reactors, and many other electrical pieces of equipment.
