ok all

edit 10-16-2007 as of this time  all photos are correct all wire are correct for my core (my choice)

here is the 4 coils on core  first layer.

edit  added wraped  with  fiberglass  insulators

front and inter coil  is 48 turns 20 ga
the top and bottom is 32 turns 20 ga
(at time could not get solid wire)
then the secondary  is 128 turns 16 ga  tifflon  silver coated  stranded  (my choice)
my 6 primarys will be 20 turns  of 16 ga  tifflon  silver coated  stranded  (my choice)

Looks good!  You wind quickly ;D

to all 

took about 2 hour each to wind each one  the middle the hardest
fingers  got real tired     did  one  a knight

this is my  pwm3f-hd board
doing a power test  befor putting  in the chips

Hey Wer,

Awesome Coil man!! Looks like a beauty. Keep up the good work :).

God Bless,

@ All

second dary layer done

09-23-07  new  winding ccw

@ Wer

Beautiful work, my friend!

I almost can't wait to get back from my vacation and to start winding.  Are you going to wind three primaries or six?

Warm regards,
Bruce

hello Bruce  and all

had to rewind core the new core will have
6 prymarys at 20 turns each

To ALL builders


i used 20 ga wire for all 4 coils and it took  about 208 ft
all coils are ccw  but bottom one it is cw looked at Bobs pics to see direction.

i wound the center coil on a Insulated  soda can holder, soft foam type.
a tad less than 3 1/2 inches across,  then fed the wire in  one winding at a time,
i also used a 3m contact spray adhesive to hold the wires in place.  it takes a while.

thanks
wer


Thanks a bunch Weri! 

I just wound 48 turns of the magnetic bias.  A bit harder to do than it looks, but it came out pretty!  I plan on winding one segment a night.

Thanks for the info...you should post it on your thread, it may help others.

Warm regards,
Bruce 


  to all  i left the ends non shorted for future use. 
  easyer to short  than to un tape and quicker to get to.
  all wires comming off core will have a seprate conection on the  abs plastic electrical box
  that  i will put it in it will be12x12x6" my controller  will mount on top of box
  with the 18v battery power supply that i will use.
  will also have a verable  high/low bias control. have not built that yet.

thanks
;D

  take the first picture and print useing  microsoft picture fax  viewer
  take picture draw  0-120-240 lines then 60-180-300 if using  6 coils
  put  coil on picture then daw lines 

HERE ARE MY FINISHED CORES

   OK, I have to ask this question for prosperity and that way no misunderstandings. I 'think' I have seen two ways to wind this torrid. Secondary under the primarys and primarys under the secondary. Which way is correct?

   If someone out there has wound  using  16 and 20, do you by chance have a winds count for each? I want to measure the length of one wind then multiply by total so I can make sure to order enough wire. All would be much helpful.

thaelin

ps. think that the coil here will yeild the total count for the 20. Really just need the 16 counts.

hello All

clean up  post

Weri,

How come your Prime's are wound CW?  All else is wound for Northern Hemisphere.

Ward

it was wound wrong
it is correct now

sorry cleaning house

Hello Ward

acording to Bob they are wound ccw
he said to wind  up from middle across top then outside  to inside going around the core in a ccw motion


thanks
wer

My dear Wer,

I am so sorry to have to say this, especially knowing how much time and effort is involved in winding one of these coils, but you are incorrect.  Bob Boyce said they are wound CCW starting at the inside and winding to the outside on the top longitudinal winding.  The bottom longitudinal winding is wound CW starting from the inside and winding to the outside, because it is "flipped, and when flipped, it will be on the bottom.

The bias longitudinal winding is CCW starting from the top and winding to the bottom.  The inner core is identical, CCW starting from the top and winding to the bottom. 

The secondary is wound CCW, and this also, in a CCW direction.  The same is true with the primaries.

Bob Boyce wrote to me just a short time ago, concerned, because it appeared to be wound CW, also, to him.  He has not been able to access the forum, like the rest of us.

So sorry my friend,  hang in there!  All will learn from this.
Bruce

 to all

  i added  a picture of 2 cores 1 ccw 1 cw

@Weri

Take a look from the point of view of a CCW rotating field riding around the circle within the core. As you (the field) enter the tunnel (the coil) and pass through it, which direction are the windings turning as you are passing down that CCW path? The one you marked as CCW is actually CW to the vantage point of a CCW rotating field, and the one you have marked as CW is actually CCW to the vantage point of a rotating field. This winding direction is what determines the direction of spin interaction of the rotating field.

Bob

thank you  BOB

all need to look at the two cores

mine was wound wrong am redoing

thanks again Bob  for the info

@Bob,
Sorry to post, but this will help others.  I looked back a page and could not tell if Weri edited that diagram with "Edit" label.  It appears correct as of Sep 21.  Can't we just say a CCW winding appears as a "Left handed" or reverse thread on a bolt or nut?  In case of toroid, imagine it straightened out and observe the 'tread' direction as if it was a threaded bolt.
Ward

hello Ward

good to hear from ya

yes i edited the cores to make them corect

am rewinding my cor now

will make some changes

thanks

wer

@ All

here is a pdf   about Bob's hod system

startingt on the bottem of page 8

HI allÃ, 

over on section 1Ã,  you will find my rewoundÃ,  core with 6 primary windings  and my finished winding

have a look any coments please

Hello  ALL

Finished putting my core in a protective box.
Checked ohms  L1 dc bias  1.0 ohms, L2-L3  top and bottom coils .6 ohms, L4 center coil .5 ohms
  L5 secondary .5 ohms,  all 6 primary's are .4 ohms each. All readings were done with a greenlee  DM-110 meter.

Now i can seal this box and get on to boxing the pwm3f-hd with 18 volt battery, dewalt extra heavy duty.
This box will be metal.   Added 2 pictures.

Good thinking Wer,

I never occurred to me to encase the TPU in a box. But it makes sense, and definitely makes it easier to hook stuff up to.

I forget, do you have a controller to pulse your coil with?
