I fabricated this from a 350W 36V KXD scooter. It works great, is easy to mount up/detach, and I can throw it into my car and take it into the city.
Because I’m in a wheelchair (paraplegic since 95) it really needs a reverse. I tried every combination of the motor legs and no dice. I tried disconnecting the small multi-plug to the Halls sensors and still NG. I think if I moved the sensor signals around to reverse their vision, it might work but that’s a lot of switching! Besides, I need more torque around these hills so I’m thinking 500W wheel-hub, bigger controller and bigger battery (range is only 5 mi) so I might as well consult the knowledgeable people on this site!
Are there controllers that will do the logic for reverse (assuming brushless motor/sensored) and providing a simple switch scenario?
Writing this got me thinking: if I reverse the sequence of Halls signals (swap 1 & 3) would that alone get my motor running backwards? Or do I have to do that as well as switch a pair of phases? (I realize that with fixed timing the motor may not run real well backwards but I only need it for maneuvering, mainly on flat ground)
