Brushless motor winding class

[ray schrauwen]

Is a Leo 4092 harder to get stator out compared to other motors? It’s longer so I assume so..?

I want to play but I don’t want to butcher anything either. I should have brought a cooked gold motor.

Hey Larry, you want to team up sometime to do some of this together? When is a big question these days...

We could be the Canadian motor winding connection. At least if I get by schiznits together I could get something going.

I like doing stuff like this and I’ve got lots to practice with, in runners and out runners.

Terry said it first 5 Turn.
Is their not 5 wires in each slot??

Larry,

I'm thinking that I shouldn't have used that picture for the test. Because it is a concentrated wind, and I have not learned ya'll about them yet. I see the difference and pay it no attention but ya'll don't know how to do that yet. Another mistake on my part.

I think ya'll are looking at the slots and counting wires, and not seeing that half of those wires are a different color.

Follow a wire color in to a slot and around a tooth, that's the turns on this type. So you'll have wire going one way in a slot for one tooth, and on the other side of that same slot, the wire will be going the other way because it going around the next tooth in line.

Ray, the easiest motor out there to do is the dyna 2000kv. Because it comes apart a lot easier and can be unwound without messing up the stator insulation. The leopards are not bad to unwind either, but they can be hard to get the stator out of. They tend to use a lot of glue on those stators.

And yes, a 4092 is a big motor with a lot of glue on it. works a lot better in a press.

I like it Larry

Thanks Don. Do you use and rubber or plastic between press and stator? I have 1/16” rubber sheet I use for gripping motor cases, might go easier on insulation.

Neither Ray, I use steel and aluminum.

You should be pushing on the windings, not the stator. Your going to rip the wire out anyway aren't you. Doesn't matter if you hurt them.

OK - I have no right to be in this thread - I try to follow what's going on but I have to stop every few seconds and beat myself on the head with a frozen trout to regain my mental composure BUT all this wire winding talk reminded me of my days in the sound reinforcement biz (early 1970's) when I took a tour of the JBL speaker plant and saw the weird gadgets they used to flatwind the speaker voice coil wire - the idea being that they could wind more flat wire into the coil than if round (which then went into the ring magnet gap) to make more efficient loudspeakers. You are all probably way ahead of me on this but I'm in quaranteen/lockdown and ...whatever

Epic played with flat winds on thier brushed motors... i still have a 10x2 flat wind armature out of an epic shock that i used to run in mod TC carpet racing...LOL that was about the fastest spooling 10 turn on the market at the time...

Looking at a few pictures of some of those epic motors, they appear to have been and expensive brand. I especially like the one in a wooden box.

I hear in a private text last night, that I have a "student" who has successfully wound and run a motor on the workbench! Sez, that he will try it out in a boat this Wednesday.

Don't know why he's not bragging about it unless he's skeered that when he puts a load on it, it'll go POOF!

[T.S.Davis]

hahah I wound it once. Murdered it trying to get it back in the can. Re-wound it again. This time I made sure my stator was going to slip right in without man handling it. I also made a few cheesy tools out of oak to make my life easier. Turns out 3/4" dowel slides right in to a Dynamite stator. I was able to press the winds with the dowel, some blocks, and my trusty bench vice.

This motor died at the Florida race. All my boats took a pounding with the wind. I thought it was just a solder joint from the 1/4 throttle peddling we all did. Nope. Something else. Inside it didn't look or smell baked. Who knows. Came apart pretty easy. I suspect the Kv is now exactly the same which is all I was really after.

Guys, don't be afraid to try this. It's not that hard. Even if you do the CCW/CW wind. Although that one is clearly harder to thread. The absolute scariest part of the whole thing is stripping the leads. Another word of advice. DO NOT get that lye/salt crap on your skin. Obviously not when it's molten but not after either. Wear glasses and yer heat gloves too.

thats the one i have...all hand wound stators and with the billet machined endbell and everything.... trinityepic19motor.jpg

Terry,

I'll be outside a lot on Wednesday, I'll keep my nose in the air waiting for "that smell" of burning Dynamite!!!! LOL

Use the same prop that you normally run on that setup, unless you want to back off a little to be sure and get a successful first run. Don't expect a big increase in power on that motor because you didn't add but a little bit of copper if any, you might not even see a small increase IF YOU USE THE SAME PROP,. The big advantage comes from using a lot more prop, but because of the better wire, it doesn't burn up AS EASILY. It will still burn up, but it will be able to take a lot more before it does.


We had problems with that motor pushing it hard, after rewinding, melting the connectors off. I now use high temp solder and a butane torch to put the connectors on with, and they don't fall off anymore.

Cool looking motor!
