Wattup fellas! I just finished my first build thanks to everyone here and all the posts I vultured over the past few months. I was able to find all my info thanks to the search button but now I’m in a slight stump.
I’ll start with my setup and then my problem
-12s lipo 4x 3s zippy 5000 20c (100A?) split and spliced into 2x 6s packs.
-Gt2b with mad munkey mod from FLATLINEcustoms on thingiverse
broke first potentiometer so modded steering wheel pot to fit.
-14t enertian pulley
-38t 3D printed Kegel Hub from JuniourPotato93 on thingiverse http://www.thingiverse.com/JuniourPotato93/designs/page:1?sort=&filter=&search=Kegel
-Dual Ollin Motors
-Dual Vesc from Ollin
-BLDC Current w/ brake no reverse
-motor min regen 20
-batt max …30
-bat min regen …10
-startup boost .010 (set to .025 but didn’t test yet due to rain)
-Cut off start…39.6v
-Cut off end…36v
So she has a weird characteristic. During bench testing the motors will keep spinning for a quick moment even after release the throttle at around 60+% in display tab. Same thing happens when I’m riding. The throttle will stick on release for a sec on initial take off which gets kinda scary haha. It will also do this when I’m rolling at a fast coast and throttle in to pick up speed… Next thing I noticed is if I hold steady throttle at a good speed for a while It’ll do a quick stall back with an audible “Jump” or “stutter” noise from the motor (not the belts slipping). When I did a bench test I grabbed one motor and was able to stop it easily by hand creating the same sound and the other wheel kept spinning. I don’t have traction control enabled so I’m not sure if this is correct… Next part, last night I forgot to install a belt and went to a friends place. After a few beers : I was dying to ride so I removed the motor wires on the belt less wheel and went for a spin. I instantly noticed the problems were gone and it absolutely ripped! Hahah. After that, I started to think my dual drive issue needed more attention. Thank you guys so much, and sorry for the novel.
