how does one rewind a motor well? how long does it take? I wanted to try putting a few more turns on my 9x7... can I just add some on or do I have to start over completely?

hillzofvalp said:Yeah I want more torque. What about lower gauge wires?
They are limited but the amp limits of their controllers!hillzofvalp said:Then why is it that in the rc car world it was thought that higher turns were better for offroad and acceleration?
doesn't increasing the number of turns (by using smaller wire, but keeping the same fill %), result in the same power, just at a lower rpm? and wouldn't that be considered an increase in torque?liveforphysics said:The number of turns is 100% irrelevant to the amount of torque a motor can produce.
ok, i now i'm a noob, but this doesn't make much sense. i could see if the VOLTS were being limited, and the resultant INCREASE in amps, to match the load, resulting in, again, the same power, just lower rpm, ergo, higher torque.Arlo1 said:#2 rewinding to add turns WILL NOT GIVE YOU MORE TORQUE!!!! The only time you get more torque is if your controller is limiting the amps to much.
Hs is wound for High Speed Ht is wound for low speed. This only makes a difference in torque if you have a elcheepo uber low phase amp controller!hillzofvalp said:And what's the difference between HT and HS motors?
So my advice to you is a slightly bigger controller. I have pushed my modded 12fet at 84v to over 90amps but I dont sugest it. It seems to be happy and not get to hot in the 40-60 amp range!hillzofvalp said:I have a 29er. The point is that the wheels need to be big. My controller is a 12 FEt lyen edition.. it's got a lot of programability and capability of being modded.
I WANT MORE ACCELERATION. I don't mind topping out at 30mph. Acceleration is what counts.
How about this: buy a 2810/12 stator/motor.. swap out stator to my current wheel. go from 46.2 to 66-100V. Won't I see less heat?
Andje said:luke i bet you are the busiest person on this forum, but at some point I beg you to find the time do a simple write up of your experience with rewiring that hs. Even just a page with your thoughts, experiences and the gear choices you made would be infinetly helpful. Full hub motor rewinds are the one thing that is essentially undocumented online; i have searched for it. There is a GM rewind vid on youtube, and I know that guy with the Tesla avatar has rewound a couple, but there no one defining post explaining the wire, the calculations, the stator lining paper, the winding pattern, the tools required, the process, the tips and what not to do... I know some of the basics of what you did are outlined in the pre buy motor thread, but the full experience would be invaluable.
