hydro4f3a 011 - Motorized Pancake Coil Winder

Here is my first shot at a motorized pancake coil winder. It has an AC motor with gear reduction to 25 RPM, but that is further reduced by the chan drive to about 4 RPM. The video should reflect some of that excitement. The unit winds monofilar and bifilar pancake coils as described by Nikola Tesla (with some modern materials). The wire being used in this video is #35 heavy build - pretty small stuff.Will attempt direct drive next to see if I can run at 25 RPM. Thanks for watching.

What are you using for a roller? I am working on making something like this but have a rubber roller.

@11111111jws

A rubber roller should be OK.... The roller shown in this video is a piece of a welding tip from a MIG welder and a short piece of nylon tubing that fits snugly on the welding tip. The most important thing is that the roller spins freely and that it protects the insulation on the wire. I use a piece of wire as an "axle" that keeps the welding tip located inside the arm.

HI,

I have a couple of other videos on my pancake coil winder with slight modifications as I learn how to improve the winder. Try building the simple form first.

The video on this page is the 4 RPM motorized winder and using a thin doublestick tape and the first attempt at a linear tracking arm.

Then I made it into a direct drive unit to get the speed up to 25 RPM, but found I needed to improve the arm again. I added a movement from a microscope stage and that really helped.

i found its generally help-full to have spacing in between turns spiral coils have allot of capacitance and like smalls paces because it shorts out then you get higher losses nice job on the winder though ill try it myself but with fishing line layed beside each turn

Hi Proto9k,

Good idea on the fishing line. just need to make sure it is very close to the same diameter of the wire you are winding. That should work very well.

Hi crob,

I think I have visited your channel before - all about the spark... well I am planning some experiments to learn more about resonance. I saw a neat experiment by tinselkoala using pancake coils, and wanted to try that with low voltage and audio frequencies. Will have to read up on the directional transmitter.

@hydro4f3a This was hard a chinese arithmatic. I couldn't get it started round and found using #30 wire was near imposible to do. But I made one. (sort-of) thanks for the feedback.

hey can u send me the design for this i really really need to know how to make a flat pancake coil... if u could sterr me in the direction as find out how to make a motorized winder please let me know

[jarkonkotisivu]

That is jus excellent work! I was just looking for ideas on howto do flat coils but this is it! Fishing line is quite cheap to add there, good idea that too!

[hhoforvolts]

Just Super!!!

That's being resourceful. Excellent set up.
