Anyway i think the axle thread may be damaged so i may need some one with a lathe to help fix the threads. Are ultramotor axles oddball threads because the one nut it did come with never really threaded on right?
AFAICT, the UM I have from a Stromer uses the same axle nuts as my geared motors by Fusin, which are 12mm. Don't know what thread pitch that is, but probably whatever the default coarse thread for that size is.
They spin on easily by finger, until down to teh dropouts and tightened.
Regarding the damaged thread issue, there are posts over here:
that discuss some easier ways of fixing that besides a lathe.
Almost certainly there is nothing wrong with the motor other than the internal controller, and even that may actually work if you could command it to do things.
At worst, a hall sensor might be bad, but these things appear to be really well made, and I expect the failures that do happen are probably caused by heat over time causing premature aging of components like capacitors, more than anything else. Hard to tell since the controllers are potted, and proprietary in operation and control systems. :/
I'd guess that if you could take a Lebowski brain board and use it to drive the powerstage inside that controller, it would work just fine.
