Phil WeaselBefore i can do anything, lets find out what we are dealing with.
These (propably chinese) hubmotors dont have any useful marking that would let us find a datasheet or anything so we need to make some assumptions.The one i got has a 36V battery. Appearently these things run around 200-400W (thanks google).
So lets take 400W max. = 11A + reserve = 15A
The connector is a 5pin with red/black and 3 colors. Im about 80% certain it is 3 hall-sensors. I always assumed these things needed a more precise position sensor..... Appearently this is accurate enough for the usecase.
So lets summarize, our controller will have:
Vmax: 36-38V
Imax: 15A
5V external for sensors

Here is an article that can shed some light: https://robofoundry.medium.com/cheaper-way-to-control-hoverboard-motors-79b02dd8a521. I have always wanted to use these for a cool off-road skateboard, but never got the time to do it. Do you plan to open-source the project? Or at least sell the controllers?
