Hello all I figure now is a good time for me to post a few questions and get some confirmation from the pros befor i make any fatile mistakes with my very expensive motors...
I am currently building an electric mountainboard (5th one) this one however will use diy hub motors... mechanically i have everything worked out but electrically... well this is where i need assistance as bl motors are wierd...ish
anyhow my motors i am working with are 4x t-motor u8 135kv pros...
it had 37 teeth and 42 magnets

and the original version has the same stats as the pro just not listed on the pros link so here's the original one http://www.rctigermotor.com/html/2013/E ... 28/94.html
I will be using this in conjunction with 8"wheels witch i have had past success with.
now I realize that 135kv is pretty darn high for my use of a hub motor however I purchased them due to the fae i got them at 1/5th the original price. I figured re wiring the motor from delta to wye would solve my problem and lower the kv to around 80ish wich is right about my goal. i will also be installing hall sensors into the motor at 120 degrees apart as usual after i have gotten the motor speed and general torque worked out.
HERE IS WHERE MY QUESTIONS FOR YOU ALL COME IN.
1. how is rewiring from delta to wye going to effect my power consumption? obviously i want to get as much torque as possible while preserving my range. I read somewhere that going from delta to wye I would half to double the voltage to get the same amount of amp draw as a delta to achieve original torque or power output is this true??
2. do you believe 4x of these motors will work well enough on this board? my last board used an 80-100 motor at 180 kv geared 4 to 1 on the same size wheels and the power was fantastic with sensors added. in my mind four of these these skinnier motors (8626) would add up to just over an 80100 motor just by there physical size which from my understanding is where allot of an outrunners power comes from am i right in this thinking?
Im sure ill have more questions but these are my two main ones currently.
thank you all for your help
