Tech thread: CrawlMaster 540

I need to sort out a few things before I do a preorder, and I would prefer to know the motors didn't get lost at sea!
I may have figured out an even better way to wind these up last night. Not only would it make the armature more reliable, it will also allow for better copper fill. I have to test it though, it looks good in the electrical diagram but I have made mistakes before when drawing up circuits. I can also depart from the Multiplex winding and just use a Simplex Lap pattern, which offers two more benefits that I shall wait to disclose. This will make the fifth pattern I have tried.

Well shoot, it almost worked well. The Simplex winding allowed me to get an even further 29% fill over the Multiplexed wind as shown in the first post, but with the standup brush width it allows for some serious no load currents to pass through the armature. It also doubled the KV for a specific wind count. I am going to narrow the brush width to see if I can prevent the single pole shootthrough, just for giggles. I think it would be worthwhile to at least figure out why this pattern didn't work as expected.
Narrowing the brushes did not help for this particular wind. So sorry, try again.
As usual I over tech a thread and kill it 
So not being satisfied with letting the Simplex wind go, I started testing other winds and motor speeds to see how the Simplex wind stacked up. It looks like it may be a viable wind for max power, as it has a similar no load current to a Multiplexed wind of the same speed. Anybody want to see some diagrams or pics of what I am talking about, or are you satisfied enough with just seeing a motor run?

Diagrams and pics as well please. "thumbsup"
Let's see some diagrams, pics, and a motor running. :mrgreen:

Heck ya JRH toss up some diagrams... finally got time to log on and check this thing out.. sounds sick! Too bad I ordered my motor for my sporty already... might be a good option for my xr in the future... time will tell lol... till then lets see the good stuff... picture's worth a thousand words right?

I would definitely like to see some diagrams and pics "thumbsup"
Right on! I will get working and see if I can get some CAD drawing up to represent what is going on. I can draw it by hand, but you don't want to see that :lol:
I have found that certain winds work better with certain patterns. For example, if we want a speed similar to a 27t motor we can use the DD Fat Pack I came up with or we can use the standard arcing pattern. They both have about the same amount of copper. If we slow it down to the speed of a 35t motor, the DD Fat Pack bumps up 30% on the copper volume but the standard pattern cannot.
In other words, there won't be just one wind pattern used on these.

so a pair of these 27t equivilants should be nice on 3s? or will they need 4s?

Sounds cool... interested in seeing this!

So any updates on time or some drawings? How are these coming along?

Let me get past tax season first. Inventory count, balance the books, etc.. Then I can get back on this motor.

That's cool. Looking for new power for either my xr or sporty so I'll be watching!

Is there any chance of you doing this kind of wind for a 480 puller motor? Say a 12 or 14 turn? I would be in for a few of the arms...
