I replaced my original lishui controller with a baserunner z9, it has much higher ratings.
I loaded defaults from grin (they had the motor listed).
It uses a hall for start.
With the new controller, the start is very rough - the motor will shake/rumble, it feels like a pulsating force rather than a smooth one. If it encounters any resistance, i can hear it click and shake quite roughly.
I've seen this with the previous controller when starting uphill and i wasn't helping it, but with the baserunner it will always be rough when starting, even on flat.
It runs butter-smooth once it starts spinning though, especially in the higher rpms.
The new controller provides significantly more power and torque once the motor spins. They have a section in the manual dedicated to this but only for sensorless start, mine would be using the hall, so there's really nothing i can go on. I tried to do it sensorless, but it was much worse.
Troubleshooting i performed:
checked wiring
checked hall operation (i can see hall sensors activate in the phaserunner software)
tried adjusting wattage
performed autotune on motor (got different values than grin supplied ones)
tried to raise the power
tried to switch from hall start to sensorless (was much worse)
checked A draw from battery on start -- very low ~1-3A, i know phase currents and A draw are not exactly 1:1.
My best guess is it seems this controller cuts out current if it doesnt detect the motor spinning and tries to start it again, i see a config for motor stall timeout which i set to max (250ms).
Any ideas would be appreciated.
