Direct Drive to Diff E Revo Build

[sikeston34m]

I had some good success with the custom wound 3530 that I put in the E maxx.

My Ceramic Nitride Bearings came in for the Revo, so I figured I would get this 4130 wound for it and install them all at the same time.

I wound the stator beautifully with 6 strands of 22 awg with 4 turns on each stator pole. I pulled each turn tight as I went and it all laid really well.

After completing the Wye termination, I checked for continuity between the winds and the stator. Dead Short!

I removed the Wye termination thinking maybe it was the last set of winds that was shorted. After testing each leg of the 3 phase winding for continuity to case. I see EACH wind is shorted.

Now I get to start all over. I have decided to dress up this stator some and not pull the wires so hard. I'm gonna take a little more time next round.

When I was pulling it all back off the stator, the shorts are happening at the ends as the wire is being pulled tight.

A little sharp edge removal with a Dremel and several coats of fingernail polish should help. The fingernail polish is non-conductive and will help soften the edge.

Lesson learned. I won't be so rough this time.

What color polish are you using, will you do your nails at the same time?

It's actually Chrome Nail Polish. I hand picked it from this huge bag of little bottles that my daughter's have collected.

Naw, I won't be doing my nails.

I prefer that "Manly" look.

Ahh, the "manly" look, when was the last time you took a shower? Dirty = manly! If that is true I am only manly when I come home from work!

That sucks man, all that time spent. I still haven't gotten a chance to finish mine up, only one phase left. Holidays has me slammed.

I decided to cap each end of the stator with a plastic disk much like the Croco site uses fiber. This does help eliminate the shorting problem by giving the wire something smooth to slide against.

Much time was spent trimming and cutting them out, but it paid off. No Shorts!

It's a 4130 AXI Stator. I wound it to a 4 turn Wye using 6 strands of 22 awg. It is tight too.

That's the crimp/solder termination that I talked about earlier. It works good.
