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

The low Res as stated above is attached to this post or can be download at:

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.



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.



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

hehe it's really look more pro then mine
i winded my wire with my own hand!:)

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.
