hub motor problems

Postby » Fri Apr 21, 2017 11:17 am

have a hub motor on catrike expedition hub motor with pedelec mode works for the first 8-10 miles
then starts cutting out and running erratically running choppy and shorter in an out ,, ok the torque sensors are maybe faulty so i start to use the thottle and the motor runs great with throttle
so if it was connections , why would the motor run good in throttle mode ??
then i try to use pedelec mode again and the motor will not run right
go back to using throttle it works fine so i think its got something to do with
torque sensors ... does this make sense , has anyone had this happen to their
hubmotor ????

Can you feel more thrust above PAS mode when applying throttle? If not, you may just be hitting battery BMS cutoff with the PAS and not when using throttle because maybe your throttle doesn't apply as much throttle signal as PAS does? It's sort of a long shot but easy enough to rule out?
