I have an old BMC V2T hub motor that I use to power a mobility trike that I put together. It's been working amazingly for the last several months. However, I recently realized that I had only put two bolts in the brake rotor So, I decided to put the rest of them in there. However, I forgot that this motor uses very short brake disc bolts. I put some standard-length bolts in there and damaged it. Some small pieces of metal broke away and got into the gears.
Anyway, I immediately realized my error and got to tearing it apart. I removed all the little metal chips and smoothed out the damaged gears. Fortunately, they would still be serviceable. Upon reassembly, the motor wouldn't work properly (sounded awful and ran slowly). It acted as though I had the hall sensor wires mixes up. I checked them all multiple times. All appeared fine. I took it back apart to see if something was damaged. Everything inside seemed good. Turned smoothly. Put it back together, and it did the same thing. However, this time, it started pulling so much current that the XT90 connector at the battery started burning. Yikes!
Anyway, I'm now here scratching my head. I have no idea what might cause this. Is there a trick to reassembling a geared hub? It still seems like hall sensors crossed up would be a likely culprit, but I checked them all multiple times. Thank you for reading my long-winded post. A new wheel and motor will set me back about $800, but I'd like to give this one another shot before I give up.
