Good idea about weighing the wire. I was thinking the same thing about knowing how to rewind with the same number of counts if i cant remove it cleanly. I am looking into magnet wire currently (pun intended). Looks like there is some higher temp stuff available thats good up to 250C. No that i expect it to get that hot but maybe its just some extra insurance.
Did you guys ever thought about rewinding one motor with silver or even silver plated wire ? I know itās expensive (522 USD/kg) but would be interesting to know if itās worth the try and if it affects (greatly) the motor efficiency.
Iām coming from RC world where we actually see this kind of (small) motors and was wondering. Just asking in case someone here already gave a tryā¦
Can you please show us a picture of your stator, so i maybe can tell you why it overheated? I would not try to rewind it. Try to get some stators with hubs from alien as spare parts. Than you can at least reuse the rotors which incorporates also some work to get them streamlined.
If someone can tell me how to attach a link to some where else in this forum I could point to where I wrote about it. Yes I rewound a 83100. I purchased it at 180KV and I rewound it to I think 116 KV.
I also have burned up a 80100, I have removed all the wire from that. I plan to rewind that one some day. Currently I have a new spare 80100 in a box. So I am in no rush to rewind the other one. None of my build attempts were direct water cooling.
No I have not tried anything other than the wire I had laying around. When I did mine I used a much thicker with less stands to rewire the motor. I had to pull the wire kind of hard to make the tight bends required to wrap it. I would stay with the same original thin wire if I had a choice.I figure the motor manufactures know best.
Youāve probably already looked at this
However I occasionally have engine stutter and intermittent drop outs from programming ESC low voltage cut off too low or too high,
I think whatās happening to me is the huge full throttle load spikes voltage down or up and auto cut out kicks in!
Lower the low Voltage safety cut out worked

Iām having similar issues with my 80100. I paired with a 7.5in diameter/8in pitch alu prop and a 14S14P li-ion battery pack, flier 400a boat esc and smart 150a BMS. Basically, the main problem is that the motor starts studdering at around 12 km/h before shutting off if more throttle is given. At first, I thought my propeller had too much pitch but then I mounted it backwards to reduce its efficiency and the same problem occurred. Now Iām thinking it might just be a setting on my ESC. Any suggestions? Can it be something else? It spins really well out of the water and it can fly by itself on the water.
Yep it definitely could be just timing. Hard to tell without trying though. Iām surprised it would lose sync at 20 degrees timing as that is close to what it should be, so it could also be something else, but definitely try increase the timing first.
