I put my first ebike together last night, but something has gone wrong and the hub motor is making a grinding noise and turning at 1rpm for a 5 secs then stopping.
Before this, everything was going well. I had some gel cell batteries ( 4 x 12v ) that powered everything fine and I was able to test ride the bike around the block.
I recently set up a 12S1P LiPo pack and when I connected it everything worked fine again, but when I went to take the bike for a ride, the hub jerked a couple of times then stopped (no spraks, burning or heat noted anywhere). The wheel is now barely turning and making a grinding noise. If I connect the old gel cell batteries up, I get the same problem.
I am at a loss as I’m very new to these motors and controllers and don’t know where to start diagnosing.
Is it possible that the LiPo pack has shorted a hall connector and should I pull apart the hub to check the hall sensors as well? (I have little idea what this actually means)
Is there a way to diagnose the problem to the hub or controller?
Any help is most appreciated.
