Nice magnetic worm gear drive. Now for the big challenge of finding a usable passive magnetic bearing. One may find the Holy Grail first. :-)
This is a brilliant frictionless gear, and got me thinking. 3D printed parts with a need for low friction (motors, moving parts, etc.) could really benefit from this. Imagine frictionless machines, with magnetic bearings instead of roller bearings.
No gears to strip, no need for high-resolution prints, no rubbing plastic to wear down or heat up at high RPMs!
