having problems wounding a fast motor. is it more winds towards the armature shaft or towards the end face? i rewounded a stock armature and it sounds wicked fast! i forgot wut patterned wound i wounded :(

The best way to do it is in a pyramid, with X number of winds on the bottom row, one less on each row after that. I usually stop at three on the top, after that it is more likely to collapse. You can wind with more toward the center of the shaft, but you lose efficiency by keeping the magnetic field separated. Check out the pics, and if you have any more questions just let me know...

very neat winds you got there,i struggle to get decent pics of mine :rolleyes:

dohc- they need to be as tight as you can :) too

Thanks, it took a lot of practice to get them to that level of neatness. I just use macro mode with no flash to get the detail shots like that :D

As for tightness, oh yes indeed, that is of utmost importance. My fingers are all cramped up and sore by the time I finish one armature segment, so I usually take a little break in between.

yeah, that's why I always write down how many turns I am going to do before I start. That, and when it's pattern wound there is only a certain amount of wire you can stuff onto that lower level anyway :D

What is a pattern wound? Is winding the motor in a pyramid for called pattern wound? I hear that term a lot, but have not seen any explanation for it.

thanks for your help. i usually do a x turn with 2x2 7389 fets. my pattern is bottom row being 7 or 8, then second row, i usually stop at 14. then third row i stop at 20, i have it put towards the shaft of the armature -,-. i tried the 180 pattern wound but it makes the fets run very hot lol

Yeah, pattern wound is the pyramid looking wind. It's the most efficient because it uses less wire for the same amount of turns, and the magnetic field is very compacted. The pics I posted are pattern wound. One of these days I need to make a tutorial :rolleyes:

yeah, all of that stuff is really hard to come by any more, I have a personal stash of the good stuff that I won't sell to anyone anymore. The best thing to do now if just rewind the ATM and PN motors :mad:

Geez, thanks Arch, hope you are still liking the one I did for you :D

That eBay seller has a lot of stuff, it's just that his prices are very high, and he gets his stuff from the guy I recommended. It's a shame that nobody carries that stuff anymore...

you know, if i could find it, i would glady run it again. i took it out of a car and put it in my motor box where it nicely blends in with every other motor in there :eek:

Oh, that's easy, it's the fast one :D

If I remember correctly, I placed the caps along side the brushes, which is one of my signature moves...

Back on topic....if anybody finds a reliable source for motor parts, please let me know...

brushes no biggie, im 20 min away from rckenon (pnracing). im lookin for fat com's. for armatures, i can use those hoppin hydros. they go for 2 bucks each.

another question, whats torque good for? also how do i go about makin my motor scream x2. like say after it hits a certain rpm, pauses for .5 sec then screams even more loud kinda like 2nd speed kickin in. i had a first gen nml motor and it did that -,-

Not a problem...

dohc-Torque is what gives you the punch on the racetrack. It lets you run taller gearing without the motor feeling like it is lagging, and you don't have to wait for the motor to come into it's sweet spot.

As for the '2nd gear' thing, I have had a couple of my motors do that. Mainly the really fast ones, I guess it takes them a bit to get up to full RPM. I had one spin 105K at 7.2v, and it made the noise you are describing. I don't know how to make a motor do that on purpose though :eek:

what do you use to speed check the motors?

That's some nice work mk2. You do a lot of motor winding? If I may ask - What voltage did you get these specs at? 59.6K is fast! :D

Nice 1 M, glad to see some good pics going public of what you get up to behind closed doors ;)

He's done a wonder sorting our club motors and even though I've said it in person, here's a public thanks for your efforts. Top Man :D
