auto_identify option of kelly controller sucks.... DO NOT USE IT!
Manual swapping hall wires resolved the problem, now the engine spin faster as expected.
I am using the KBS72121X rated for 55amp continuous, it is quite overpowered for cyclone 1680w (the engine is rated for 33a continuous) and....it is quite difficult decode kelly controller settings.
Playing with the Max battery current and Max Motor Current to limit the maximum amperage i found this:
- Max Battery Current = 100% (this setting seems
to limit the max voltage not the max amperage = the engine spin low
- Max Motor Current = unlike other Kelly controller it seems to be the motor current and not the phase current (perhaps)
= 100% it means boost current (130A) for 10/30 seconds and after 55A the continuous amperage
My dumb math: 130A * 30%(Max Motor Current) = 40Amp
if you keep 100% the engine stall as soon you open the throttle.
The kelly settings now are quite similar to the original (not programmable) controller but:
- kelly is a lot more smooth than the original controller (pro)
- kelly provides less torque at low speed but good acceleration
- with the same gearing (wheel:48:12, engine:53:13) with kelly, the engine overheats more easily (cons)
The gearing is for sure not ideal, the engine spin at low speed absorbing all the amperage available and wasting energy but: how it is possible that the ultra cheap Cyclone controller provides more torque at low rpm and avoid overheating compared with fully programmable 3xExpensive Kelly controller????
someone have similar experience to share?
