First go at small coil
« on: August 04, 2009, 11:03:43 AM »
Usually I wind coils between 45mm long on 3.2mm dia core with 0.1mm dia wire to 500mm long on 25mm dia core with 0.7mm dia wire. I have just however done one for a new project that my client is working with me on. The core is 0.5mm dia, wire 0.1mm dia it is 20mm long and 6000turns.
 Had to adapt the coil winder I made to add a slaved spindle so that I could hold the core in tension whilst I was winding, worked pretty well I think :)

Hi Hood.

Could it be possible to see you coil winder in action, it would be very interesting.

Nice work, Jeff

Not much to see, it just goes back and forward and round and round LOL.
 Heres a pic of the machine itself, never having seen a coilwinder in my life I just made it like a lathe so dont know if it looks anything like a real one. My brief was that it had to do from 45mm long coils to 500mm long so it had to be adaptable.

Thanks Hood for the pic, what is the purpose of all these coil ?l

Are they special coil that can't be found on the market ?

The guy I do this work for designs all sorts of magnetic signalling and sensing equipment mainly for the Oil and Water industries, a lot of the stuff is prototype so that is why the versatile machine was needed. Dont think off the shelf coils could be had, especially with the type of cores these have, although I certainly dont know much about the coil industry.
 I know he can get coils wound to his specs but for ones and twos its not cheap and even once a design has been finalised its still cheaper to do in house.
