I just finished setting up my 3rd ebike and I am having a problem. I purchased a 48v Luna shark pack and I have paired it with a Chinese 1000w non-geared hub motor. It is throttle only with no PAS. It has an LCD control.
The issue is intermittent glitch in the power while riding. I say glitch because it is more like a bump and not a pure loss of power. It seems like one set of coils gets out of phase for a split second and causes the motor to jolt. I have already ruled out the battery since I get the same intermittent problem with a different battery. I believe it is a loose connection, interference between cables, or a bad hall sensor. I have checked all the connections visually. I am sure it is not the main power connector. I can rule out the brake cutoff since that behaves differently (smooth cut in power.) That leave me with the LDC display control, the throttle cable or the hall cables/sensors.
Given all this info, which of those is the most likely culprit? Which would be the most sensitive to inductive interference? This may be a tough nut to crack and I am hoping someone has seen this exact issue before.
Many thanks,
Robert
