Please use the Tabs above to navigate to the information you require.

This machine has been designed to mainly do Guitar Bobbins (Pickups) that use thin wire and we will be supplying it with a bobbin wheel mounted directly on the motor shaft.

It has multiple spacing to accommodate most Guitar Bobbins out there and also pockets for magnets.

It can be used for semi automatic winding of Guitar Bobbins by just using the bobbin motor and guiding the wire by hand or you can use the fully automated feeder arm that has a incremental resolution of 0.0125mm

The Machine has a small footprint of 200mm x 200mm.

A combination of 6mm and 10mm tough aluminium plates that have oxidisation treatment applied make up a solid frame.

This stops any unwanted vibration or flex.

USB controlled using software written for Windows.

Power supply and all leads needed will also be supplied.

Please note that we despatch with a UK mains plug on the lead. If outside the UK then you will need to cut this off and put a suitable plug onto the lead.

The controller box is mounted to the base and you simply plug in a 24 Volt DC adapter that is supplied with the machine and connect it to the USB port of the computer via the USB socket on the side of the controller box.

We will supply a pack of magnets, but you will need to glue these in yourselves, as not everyone will require the magnets and also you can then choose which way around you want to mount the magnets.

The reason we have gone for two stepper motors this time is because we have managed to design a unique way of driving the motors at high RPM. Typically Stepper motors are good for around 650-700 RPM but with the new control circuit we have designed the stepper max out at about 5000 RPM !!!

But do not get too excited as at those kind of speed the torque is very low, so we have limited the speed to 1500RPM

This is more than enough for winding Guitar Bobbins as many of the guys will tell you.

We recommend running the machine at 800 RPM

The front panel has two LED’s, the Green shows power and when switched into Manual mode the Red LED will light up.

The small 3.5mm jack socket is for the speed controller to plug into.

As you can also see it uses high quality Hiwin style carriages for the feeder arm and also the revolving tailstock.

This allows the tailstock to be slid and secured against the bobbin without any flex or movement.

 
Please note that this machine is not designed to be a commercial machine that can be ran in a production environment 24/7.

This is designed for prototyping and small batch runs and hence the low price.

Also this machine is still in development, so please expect software, firmware and hardware upgrades as we strive to improve it. While the software and firmware upgrades will remain free, any hardware changes will be an additional charge if you choose to upgrade your machine.

The Mini Coil Winder is controlled via the USB port of a PC running Windows, along with our custom software that is supplied FREE.

As you can see it has a dedicated database and GUI for Guitar Pickups but no reason why you could not wind small normal coils with it using the Standard bobbin page.

The resolution pitch of the Mini Coil Winder belt system is 0.0125mm resolution steps with a minimum pitch of 0.0250mm

The software will calculate the nearest layer count based on the pitch you choose so you can see how close you are to the original.

Playing with the software will probably make more sense than me trying to explain!

Also the software comes with a populate button that will load the built in database with a default set of common guitar pickup bobbins.

You can also save and remove your own custom bobbins.

If you need a machine for larger wire sizes and more torque on the bobbin motor, then please feel free to contact us and we can quote on a custom made machine to suit your needs.

Above screenshot is of the Manual mode.

Here you can plug in the little box with the dial and manually control the speed of the bobbin motor while guiding the wire by hand. This allows the machine to be used as a traditional winding machine.

But also you can now manually control the speed of both the bobbin motor and the feeder motor by using the Automated Coil Winding tab controls.

If using the Manual Controller from the Automated Coil Winding Tab then it is not recommended to run the machine full time with the manual speed controller. This is just to be used as a calibration tool, which will let you determine the best speed for winding the particular bobbin with wire you are using. Once you have found a speed that suits the bobbin and wire combination then you should switch to automatic mode for full winding.

On the tension arm we have lathed down the first section to allow you to manually guide the wire.

With the new software you can use features now that were only available on the 200mm Coil Winder.

This includes the Script Engine that will allow you to build up a list of commands to do a combination of fancy windings.

Please feel free to download and take a look at the latest software from the Downloads page

We have developed a new controller board that uses a fast Arm Cortex M4 processor and brings many enhanced features to the machine.

All machines despatched from June 2015 onwards will be supplied with the new Arm Controller.

Upgrade options are available for older machines.
