tIANci, It would be difficult for me to determine what caused the damage/failure to this motor wihtout actually examining it. There appears to be a slight amount of discoloration
to the copper windings in the above pictures. The magnets appear to be intact with only a minimal amount of scuffing/normal wear & tear. My good guess is that basically it was
defective to start with or it was over propped which in turn causes excessive heat & ultimate failure. Again, this is all speculation on my part & not from one who knows definitively. After runnning the AXI's for 3 years, I found they too are not without their faults. You all are more than welcome to migrate to the U.S. As for the great weather, we experienced 17 degrees F last Sunday morning here in the great state of Tennessee! It's gotten warmer since & we all hope spring is here. Regards_____TNWalker
