Brian,
Please don't let this go away. I am flabbergasted how Ron has danced around this topic. It could have been worked out weeks ago with one simple answer.
One clear winding diagram.
thanks,
jimbo

Waiting for Ron...
There is an old saying we use here in the west. "S or get off the pot"

Which wires to which

Simple, I don't have a drawing and I don't know it of the top of my head. And heavy thinking has not been my priority these last two months. Something else on my mind, sorry.

Groeten Ron

A diagram isn't necessary. Its been stated many times that you connect the 3 starts together and the 3 ends to the ESC for Y. That's all there is to it. Since we are winding our own motors it should be simple to keep track.
If you have to have a diagram Gertjan has one:

Jimbo and Brian, please be patient: hoping to help Ron, I'll try tomorrow to post a drawing and an explanation on HOW I MAKE MY LRK's... plus the complication of parallel and series connection of the two opposite teeth

When winding, does it matter from what direction i wind the stator teeth? Lets say I am going to wind 20 turns, I start at root and goes to the tip, at this time it has 10 turns.
Now I am winding back towards the root and get 20 turns when reaching the root.
Is this the correct way, or should i start at tip?

Wheazel: It makes it *neater* if you start AND end at the root. It's not vital however. It gets the winds out of the way of the other windings is all. You might discover this when doing the 3rd winding.

OK .. I will not contest anything, merely make a few points this time.

Ron forgive me for being so blunt, bit I suspected you were not sure of the correct answer all along. It is the only explanation for your lack of decisive feedback, for which we all have the up most respect for here.

However, this post

Correct Brad/arx_n_sparx/Igor (when will you make up your mind, are you schizofrenic by any chance ?), otherwise you end up with 60, 60, 240 degrees difference between the phases instead of 120, 120, 120

Groeten Ron
Is a bit up in the air. Don’t know what you are saying or who you are agreeing with. I think it may have fueled more confusion, as it would indicate that you did know something on this issue and perhaps holding back. Or maybe I am just missing the point completely.

Have a look at the distributed Y diagram below. Your statement is contesting “5 years of German engineering” as somebody else here put it to me.

As far as my drawings go, seems nobody has taken the time to study them.

Max.ferra.

If I take your numbers and put them to a drawing via a puzzle solving exercise, I get the attached configuration. It’s the only way the pieces can fit. If this is correct, you and I will see eye to eye on this and agree with what I have being saying all along.

Brian: It seems to me that you have a mind block about this. I'm looking at the posted diagram you put into the post above. Would you agree that ALL of the "S" windings are clockwise looking from *the outside of the stator towards the inside*? IF you continue to look at those windings *from the start*, then the other coils are CCW. Notice that the 3 "S" windings are tied together for a Y/Wye connection. As Ron said, you have to be at 120° apart on these. Ron isn't "hiding" anything; I'm glad this point came up so that we can clarify things. You HAVE to be at 120°/120°/120° or else you end up with a motor that doesn't work well.

360°/3Φ = 120°

Just my 2¢

Brad

IN your autocad drawing, you would hook up either 135, or 246

<edit> scratch that - there's a mistake in there - gimme a minute

AW, heck - just draw a center line through the middle of the rotor, and tie one side together. (I'm looking at the pic with the black background)

Brad

<edit> NOw that I look at it, same applied to the top pic with R1-3 and S1-3. Bisect the rotor, and attach one half of the leads together

Hi all
I completed a .doc file, it's 282kb and I cannot attach it here.
So I uploaded the file on the "file" folder of LRK-torquemax mailing list.

http://groups.yahoo.com/group/lrk-to...les/max.ferra/

You need to be a member of that mailing list.

Please feel free to give any suggestion and comments.

Yes. It's no use telling about things that one doesn't know. In my case, the forum would explode

Throw in a couple of extra (+/-50), less frequent outrunner harrassed newsgroups, mailinglists and fora and you get the picture.
All for the good course naturally
