Re: Sensor of Sensorless Controller...?

I would go with the complete crystalyte system but one thing needs to be fixed with the hs3540, i think something of a rubberpart near the wires going into the wheel. after some times the rubber seal reveals a string of metal, solved with changing it to a 100% rubber one. seems to be easy fix. 48v, ...

Seems to be a phase wire that play kid.

Going for a sensorless controller to make it work. Plain simple i hope. Also abän extra throttle
Maybe o blowed mine when i put the electric wires opposite +-

Oped my controller and i saw no nothing odd
All cables connected. No fried stuff or blow capacitors
