Even if you shorted your windings for sure, I can not understand how you’d damage the rotor this way…
The 6384 and 63100 motors are proven to work. Take a look at this thread for exemple, but there are plenty of others on this site :
This motor won’t allow you to attach the prop on the shaft unless you revert it, so basically, if the design allows it, push the shaft to pop out the other way and fix it again with a circlip. I know some motors can be reverted but I don’t know about this one in particular. Alternately, you can attach the propeller directly on the bell and not the shaft itself like many are doing.
If you are in EU and look for proven to work motors, take a look at :
