What You Need to Know About Coil Winding Machines

by Stanley

A coil winding machine is an essential component in manufacturing of coils. The machine influences the winding pattern, quality and quantity of coils.

In most cases, people think that any machine that can rotate a coil or bobbin is a perfect pick. Well, they’re wrong. The coil winding machine is an essential selection of the entire coil winding process.

Here is a write up that discusses the vital requirements in the manufacture of electrical coils. Be sure to contact Kobao for assistance on this.

  1. The Non-Orthocyclic Winding

The pattern is most common in winding coils. The coil has a number of layers with the length or width fixed to the bobbin.

The turns are carefully wound onto each other in a specific layer. As the winding continues, its direction changes leaving the width or the bobbin layer intact.

So, the layers are skewed in a reverse direction. The degree of skew is same as the diameter of the wire. But why?

To ensure you don’t compare the turns as you compare between different layers. For instance, if one skew is from the right, the other one will be from left.

In this pattern, the coil will leave some air gaps between the coils. Air gap in the coil is highly discouraged. But why? If the air heats up, it’ll raise the temperature and may destroy the entire coil.

In order to avoid this gap, coil varnishing is done a number of times. In this way, the entire gap is filled with varnish. But if the winding is done normally, it becomes impossible to avoid this space.

So, you’ll need an additional space to fill up the number of turns that a coil needs. In this pattern, at least 75perecent of the total space is used by your wires.

But if the air gap can be avoided within two turns, more turns can be wound to reduce the air gap. As such, heating the coil becomes quite easier. That’s why it’s known as Non-Orthocyclic winding.

  1. Orthocyclic Winding

The process is also known as parallel winding. Here the winding is done on a location. As such you shift the wire for the next turn to the next location.

The turn goes constantly on every turn wound and every layer. So, the turns are either straight or parallel to one another. But there is an exception where you turn the fraction of a turn to the next turn.

The turn you create on the next layer is at the middle of two layers. This has an effect of reducing the air gap within these turns.

The patterns makes it simple to get maximum copper filling within a given area of bobbin. With this method, the density of turns is higher at around 90 percent.

With such a higher density, the winding pattern is ideal for high quality performance of electrical coils.
