Before Cycloidal Gearboxes, I research Concentric Magneti Gearboxes. 

I made an improvement on the current design by drastically reducing the flux path length and hence increasing the torque handling ability.

really cool. I always wonder if you can make a variable gearbox with magnets..

  Are you sure? yes | no

I think that that has been done in conjunction with a motor called pseudo direct drive.
