Hello EV Friends,
i bought a new 1500W hub motor and connected it to a Kelly KBS48101X. I tried all the 36 possible hall and phase combinations with 120° hall angle and as usual three of them seemed to work fine on the assembly stand but i couldn't tell any difference at those three combs. Neither from the sound and behavior nor from the current shown on the cycle analyst.
When i tried to ride the bike the first time i noticed that the motor runs quite rough, noisy and even vibrates especially at start and slow speed. At higher speed its quieter and smoother. So i tried all the three combs that worked fine with the wheel lifted up but didn't get any better solutions. I also tried the "auto identify" function and switched between torque, speed and balance mode and tried the "quiet" settings but with the same result. I haven't checked the hall sensors of the motor yet but as it's brand new and i also got no hall error i assumed they are fine. Maybe it's worth mentioning that i connected a stand alone Cycle analyst V3 with the external shunt kit and connected the yellow hall sensor wire from the motor in parallel to the CA for the speed reading but have the throttle connected directly to the controller because i want to solve the problem first. As i have a bike with the same motor and a controller from the kit and a bike with a mxus 3k turbo and a sabvoton controller i know how smooth hubmoters usually run.
So i really don't know what else i could try or do to make it run smooth and need your help.
Thanks for your help.
Best regards
