Ok. thanx. no more battery shipping questions on this threadmarcexec wrote:Just USPS - feel free to send me a PM (I really don't mind), this is derailing the thread a little.

In seriousness, the design allows for a 2nd 80-100 and the batteries will be placed so a Colossus or Motenergy type (usually 200mm) motor can be added.
Pics to follow on (further) gearbox modification.
Cheers. Sounds like an interesting project. Would you go 60Ah, too?hehe
if you want to stay with infineon controller, you are probably limited to motenergy, inductance wise.
otherwise sevcon + pms120 motor would be wise choice ( tomaj is selling in forum for reasonable price) for
your frame and leaf battery. I was tempted myself, but I still have a me907 and infineon 36fet to put to
good use. I plan to convert an enduro 2stroke 125, sooner or later, with Leaf module hopefully.
I plan to preserve the gearbox, probably reduced from 6 to 3 gears .... if luck help.
Clutch is already dry and cosy.
Hehe, nono, for the beginning I would like to keep the bike as light as possible: just 4 modules!marcexec wrote: Cheers. Sounds like an interesting project. Would you go 60Ah, too?
I still have 2x 80100s in my mind for some reason. Could test different setups etc. Take one off for a rewind. You get the idea. Who knows about stage 2. Need to get her on the road now to save me some gas first, though
Appreciate it gwhy! - have a look at the paperweight on my desk - might give it a try myself before resorting to a specialist:gwhy! wrote:What controller are you using ?.. I don't know how much it will all cost but if you wanted to pay for postage to the uk plus materials I would rewind your motor for you.. drop me a PM ?.
That leads us to 7 turns in WYE (preferred) or 12-13 turns in deltaThud wrote: I've been trying to reverse engineer the constant to estimate the Kv for this size motor, based on the sparse data we have at the moment. This is what I've come up with in terms of turns and Kv:
Turns - Kv
1 - 1060
2 - 530
3 - 353
4 - 265
5 - 212
6 - 177
7 - 151
8 - 132
9 - 118
10 - 106
11 - 96
12 - 88
13 - 82
14 - 76
These figures are pretty much the best fit I can get to the known data points, and they would apply equally to someone rewinding an 80-100 motor
Again, Thanks to Jeremy Harris.
I have found this chart to be super accurate with the 80/100 turnigy's & all RPM's are assumed terminated in Delta...
for a lower RPM "Wye" termination, divide by 1.73 to get your new Kv example- 132/1.73= 76-Kv
To me it looks more like 1.18mm, so 17AWGmarcexec wrote:to this:
looks like .8mm net, so around 20AWG
yes 5 in a ideal world but soon as you start going over 2 layers it becomes very difficult, I would always look at around 1.5 layers as a max .. but having said that I use 1.4 and 1.5mm wire so you maybe able to fit 2 layers with ease with 1.18mm but the 3rd layer will start to become a nightmare . Yes doing a test is always the best thing to do..marcexec wrote:Drivecalc says 5 - found the source It think: http://www.brocott.co.uk/enamelled-copp ... 8-500.html
I'll check how much turns I can actually fit around 2 teeth. One test is worth 1000...
