Brushless motor winding class

[donhuff]

That's right Terry, any wire not in the slots does nothing. My understanding is that if it's not against the steel, or against another strand, that is against the steel, you get no benefit from it.

That's just a part of the DISTRIBUTED wind that sux. But now on the CONCENTRATED wind, the end turns are always tight against the steel and DO add something to the fire.

Look at pics of outrunner stators. That's what's called concentrated winding. Each coil has it's own chunk of steel with no breaks in it like our motors have. And the coils don't overlap each other.

All of our normal motors are the distributed type. There are some concentrated inrunners but they are rare and are usually made for a specific task. Buggies and truggies like them cause the cog less.

OH I forgot,

Yes I like that drawing better. Spreads it out more so it's not so bunched up. Easier to read.

I don't think that we need a three turn drawing. If ya can't figure out that you just add more turns...to get more turns.... ya probably ought to take up knitting.

There Terry, a shot of the bottom side shows all three turns making a complete loop.

Just ordered some 200c magnet wire. I have a number of motors I can practice this process on. Great stuff so far Don.

I'll make that goofy CW/CCW drawing when you get to it.

I just noticed something by looking at the last picture for a little.

There are three DEAD teeth! In between each set of coils, there is one tooth with no wire around it. I never noticed that before and thought that all of them were being used.

I'll have to do a WYE next and we'll see if it ends up the same way. I don't think it does. The Y starts off totally different too.

There ya go Terry. Your doing so good I think you'll be able to get it from this limited drawing.

In STS to the right then up,were going CCW here, do one more turn in the same coil and out the top, sts to the right and back in. notice now that you go CW back to the up side of the first coil and through. That makes the third pass through that slot and I'm thinking that's the third turn for the first coil, well it's half of it, we'll get the other half on the downward pass on the third coil of this set. Now finish the second turn of the second coil, (note that there will be 6 coils total, in a way, for each leg in this one) down and out the bottom, sts to the right again and make another CCW coil which finishes the third pass on the second coil and finishes up with the second pass of the third coil!! Holy crap, I'm getting dizzy............... CW again etc etc You end up with the next to last pass going in at the very start slot where there are only two passes through it and the lead is sticking out. That next to last pass gets us the third pass on the first coil on the starting side. Then continuing CW, sts and go up and out for the finish.


I TOLD YOU IT WAS DIFFICULT!!

And remember that when your drawing it, the wire will run off the edge of the flat stator to the right, and will go on to the first three slots on the left, then will come back to the last three slots on the right.

Well Terry, that 200c wire is the best, but if you haven't mastered the hot ass LYE thing, you wont be able to use it. There's no other simple way to get the insulation off!

Don - will the antifreeze dip work on this wire??

Larry

[donhuff]

Yes Larry it does. I did that for a little while just trying to come up with something besides the Lye, that wasn't so dangerous and painful.

The antifreeze will work but it's so danged slow.

Already did that on and old motor. Scary but not hard.

[donhuff]

OK good. The lye makes it all a lot easier to do. Especially when we do a Wye bundle.

[donhuff]

Terry, can you understand the CW/CCW drawing and text?

The drawing looks simple enough when there is just one leg on it. But add the other two legs, and holy ship it's a mess!

The text will have you pulling your hair out real quick, unless you kinda know what's going on. But by following the drawing with a finger, you'll see it just two turns one way, then two the other way, then do it again a few times until you run out of slots.

[T.S.Davis]

I clearly have this one screwed up. Help me fellas.
