My Hi-Q screwdriver antenna uses a resettable fuse that opens when the drive hits top or bottom, takes a few minutes to reset after the current subsides, and you save the motor. Seems the simplest fix to the rotor.

Yes, it does. Do you know the rating of the fuse? Does it heat on its own, or is it attached thermally somehow to the motor?
