Hello,
I'm trying to upgrade from a 25A controller to a Sabvoton 7245 from RisunMotor. I'm running a XOFO 175 750w motor that according to their technical specs has a 120 hall angle.
I've tried all six possible phase wires connections, three did spin the motors and three didn't as expected.
From the three that worked,had 305, 63 and 188 when running hall test. Only the setups that returned 63 and 188 also worked when setting hall angle to 120 manually, so I've already discarded 305 setup as a possible combination. The setup that returned 188 did some strange noises when in WOT, so I'm assuming that it was a false positive.
That let me with the setup that returned 63 as a hall angle, which also works setting angle to 120 manually. However, as soon as I put load on the bike and try to accelerate, it stutters with a impact driver noise on either angle setting, however after getting past 13mph it just seems to run smooth, and current draw seems to be reasonable.
My motor parameter in the app is set to 1000 and changing any other settings have no impact on that no power stuttering start. Does it make sense to try other hall sensor connections until I can get self test to return 120 angle? I'm very new to the ebike universe and did look around some topics, but couldn't come to any viable solution.
