10 W
Just installed a new motor and controller. Found the right phase combo, Wide open throttle draw at .8 Amps, minor noise on startup. But when going 15-20mph and I hit the throttle hard, the motor makes a terrible NOISE (pedestrians will turn their heads at the sound), chokes, suddenly gets restistive and drags, and stutters. Amp draw at this time is 5-15. This is on a flat part of road. However on the hill to my home, I will be going slower and drawing 20 amps with no stutter-NOISE drama.
Backstory- Sadly, I thought it time to retire my old Wilderness Energy brushed motor that I installed 10 years ago. Thought I'd replace it with a 350W motor and a 22A 9-Fet Brainpower controller. I was going to use my CA to limit the amps to something reasonable.
I loved that old Wilderness motor, quiet as a mouse, could take 30A but it wasn't efficient and it refused to die to make an upgrade an easy choice. I've built a mid drive in the mean time. This is my first try with a brushless, maybe I'm missing something simple.
So I bought a 350W front hub a few years ago anticipating the death of my Wilderness motor, I think I bought a geared one. The controller I got last month. 5 pin halls on motor, 5 pin halls on controller. Left the halls static ie. plugged together, tried the 6 different phase connections. Found the false positives phase connections, and the correct positive with 0.8A WOT. Used the self learn pins to confirm, unplugged when done.
Ideas?
My suspects-
Throttle voltages out of spec
Speed restriction built in? (not supported by WOT conditions)
Bad hall sensor?
