Well a good day in the workshop today and getting there, so an update from me :)

First picture below is a re-hash of the 50mm * 10mm Magnet I am going to use.
I did not like the brass holding setup that I did last weekend, so now have milled out two halves of 8mm polycarbonate to set it in. I will tap out the end and put a thread on the axle.
The width came out at 70mm side to side.

(http://www.overunity.org.uk/clanz-newman1.jpg)

Next I found some Carboard tubing which was 82mm external and 75mm internal. Excellent this will give me a nice close gap for the magnet to coil.
I then milled out two 140mm end caps, this will do two things.
1.) Hold the carboard tube in place while winding and also form a lip.
2.) Leaving base plate on after the winding that will give a nice stand.

(http://www.overunity.org.uk/clanz-newman2.jpg)

I then glued the two end caps to the tube and also milled out some couplers, so I could attach it to the winding machines axle.
I wanted to be able to remove the couplers from the end caps after the coil winding was done, so instead of glueing the couplers I tapped out some holes and used come bolts.

(http://www.overunity.org.uk/clanz-newman3.jpg)

The only thing missing now is how to get the Axle through the carboard, so lathed and threaded some 20mm Perspex bar. I then drill a 8mm hole through to take the 6mm axle.
I will mill out two bearing holders for the end of these rods after it is wound.
I drill some holes in the cardboard tube and the bars screwed in nicely and became rigid as they tightened up.
In the background the middle magnet has been pressed into it's new housing a couple of clamps will hold it tight as the glue dries.

(http://www.overunity.org.uk/clanz-newman4.jpg)

Below you can see the Axle Tubes mounted into the cardboard.

Final picture below is with the TO-BE coil mounted in my home made winding machine.
I have used the parts that I build my milling machines out of.
So top Axis stepper simply turns the axle with TO-BE coil attached and bottom Axis Stepper will move side to side with precision accuracy.
Just have to now make a reel mount for the source wire and a tensioner to feed the wire.

(http://www.overunity.org.uk/clanz-newman6.jpg)

Will spend tomorrow rigging up the steppers to a circuit and writing some code to control it.
Nice thing with the steppers is that I should be able to write the code so the wire gets evenly wrapped around the Perspex Bar as it moves along.

More to come

Regards

Sean.

Hi Newman Machine amazing builders!

@The Initial 'flower pot' constructor...
@The (Very) One, Mramos and others clever manufacturers...
Thank you. Great jobs.

I whish I also had my own sparkling device. But do I absolutely need a flower pot? ;D

@Harti_Berlin: Thanks also for your precious advices.
As I can guess it, you have built a Newman machine with huge windings. My French current supplier does not deliver large insulated copper wire spool. Most of big French compagnies frown upon selling retail or to individuals.
My question is : could you direct me (and others) to a serious German compagny (yes, 'serious' and 'German' is a pleonasm. Is it not?  :)) wich could agree to sell a single big coper wire spools (0.5 m/m  and 3 or 5 kg or more for example) and to send such item in France?

Best

@ Clanzer
 :o
You've out done yourself this time...
Thats a beautiful winging rig and plastic body for the motor.
Even though your rig appears to be the most complex and persice
you'll still probably beat most of us to replication.

Your build speed is amazing!!!

Are the magnets supposed to touch the axel or are the spaces supposed to keep the magnets from contacting with the axel? sorry just there are still things im not 100% certain about i thought maybe the magnets dont touch the axel and the spacers is what sticks to the axel, and also are the magnets supposed to have opposite poles faceing each other or not?

the magnet can touch it its not really important, they just need to be fixed on the shaft

@ Clanzer

Very Nice Indeed!

@seekingknowledge

the magnets should be in 'attraction mode' that is attracted to each other

YAY!!!

I built the recipricating version first... It works great!
More vibrate than recipricate, but it does work like described.
I'll keep messing with it while I build the flower pot motor next.

LOL... Flower pot motor...
::grin::

P.S. I'll try to post the pics tomorrow... too tired tonight.

What a day !!! Not even opened my Fathers day cards yet :)

Okay got the Coil Winding machine going today and well pleased with it. I took it at a low speed to start with but will speed it up when doing other coils, but for now did not want to push it.

I have attached a small video but also have uploaded a hi res video for people that have the bandwidth.
The Hi-Res Video can be download from
http://www.overunity.org.uk/CLaNZeRSCoilWindingMachine.avi   (60Meg)

The low Res as stated above is attached to this post or can be download at:
http://www.overunity.org.uk/CLaNZeRSCoilWindingMachine.wmv   (3.5Meg)

I used two stepper motors that require 200 pulses per revolution.
The Stepper controller unit I am uses is set to 1/8th mode so 1600 pulses will turn each stepper 1 full revolution.

The TO-BE coil is attached to a direct shaft and so that was easy enough, just send 1600 pulses to the stepper and I got my full turn.

The other Axis simply moved along 0.25mm after each revolution as the wire was 0.25mm thick.
The Axis is on a trapezium thread which gives 3MM travel per revolution (Tr 12x3) so 1600 pulses will make it travel 3MM, so I simply divided that down and that gave me 133 pulses to make it travel 0.25 after each revolution.
After 85 revolutions it hit the Rod stuck in the To-BE Coil and so I simply told the code that after it had done 85 revolutions to move the Axle 17mm across and hence avoiding the 16mm Rod.
It then did another 85 winds and reversed it self, again doing the 17MM skip on th way back.

Below is a picture of the coil nearly finished on the Winding Rig.
I ended up winding 1955 turns and got 188 ohms. I was gonna leave it running longer to get over 200 ohms but the wire got snagged when I was not paying attention and broke :(.
But will try it at 188 ohms for now.
It is 34swg 0.25MM wire I have used.

(http://www.overunity.org.uk/clanwound1.jpg)

After I had finished winding it, I tape it up and snapped off the top lid to end up with the finished Pot Motor below.

(http://www.overunity.org.uk/clanwound2.jpg)

The Magnet holder glue has now all dried and off to lathe down some bars and put a thread on them.
Then all that is left is to Mill out some bearing holders to go on the end of the Axle poles and put her together.

Main thing I have learnt off this is that I did not need the huge 140mm end Caps as took less wire than I thought.
But good for Mark 1 of the Pot Motor :)

More to come, but may have to wait to next weekend !!

Cheers

Sean.

As long as the end result is the same TheOne :)

I am just a lazy Git and look at anyway of getting around bordem LOL

Been meaning to try out a few projects that require coils but the hand winding always put me off, so now I can catch up on those projects as well.

Now got to find time to catch up on the threads before another week away from home :(

Keep up the good work that end.

Regards

Sean.

Thanks a Lot CLaNZeR!

At last some one who think about teaching us Mortals, that do not understand much of electronics, a lot of people like me are following you, thats for sure.
Thank?s again!
Good luck, and happy father?s day.
