Hey, I could help with those motors, but I would use them on my inline skates. Didn't post my build here yet, but its called Thundrblade. I've been posting inside Vanarians build post
So far I'm using all hobby parts (waiting for my VESCs) and friction drive. I want to try hub motors, but it seems really hard to build them myself with little to no money and no access to a lathe and mill.
I read through the whole thread in a couple days and got confused at some point.
So far I understand that this hub motor you designed is screwed into the trucks. Is it possible to run a bolt through it?
Also I have a question about the motor. How is the can supported? I know there is a bearing on the 8mm axle on one side, but where is the other one? You should need 2 points of support for the can or it would not withstand the weight.
So, I would make my own rubber or adapt an existing inline skate wheel, since I have a 3D printer should be easy enough. Do you think its possible? how wide is the motor?
