Hello,
I am in the process of finishing a new build based on the LR single stage (small block) kit. I'm using a Powervelocity 12FET sin controller, and a CA3. I am running the throttle directly into the CA3 and only using the CA3 harness to the controller.
I am running the CA3 in pass thru mode. If I gun the throttle with the bike lifted off the ground, the motor spins up just fine, but if I'm riding the bike, the motor 'sputters' like a gas motor running out of gas. I am pretty sure the phase and hall wires are correct since the motor has no trouble starting up. The current draw is also fine, and the controller and motor is not running hot.
I played with lots of setting in the IOS phone app for the powervelocity controller. I disabled flux weakening, played with phase current and battery current. I am now running 40A battery/130A Phase, but have tried lower values with the same result. The data displayed by the CA3 looks ok...throttle in and out voltages, current draw, etc. Nothing looks weird and I'm not seeing any limit flags. The sputter seems to be torque related since it happens more when going uphill and when I open the throttle fast.
I realize my next step should be to eliminate the CA3 from the equation and run a throttle direct to the controller. I just wanted to know if anyone has had a similar symptom?
Thanks,
Regards,
Brian
